As a versatile raw material, hydrogen peroxide (H 2 O 2 ) is extensively employed in chemicals synthesis, medical disinfection, textile industry, and environmental remediation fields. H 2 O 2 generation through a photocatalytic route has attracted increasing interest. Tremendous progress and achievements have been made over the past decades in photocatalytic H 2 O 2 production. Herein, we critically review the state-of-the art developments on various photocatalysts, including carbon nitride, titania, bismuth, sulfide, carbon, and metal-organic-compound-related materials, for the highly efficient light-driven H 2 O 2 synthesis. Significantly, these materials show tunable morphology, micro-nanostructure, surface chemistry, and electronic band-gap structure characters for sufficient light harvesting, rapid hole-electron pairs separation and transfer, and favorable reactants adsorption as well as facilitated products desorption, thus delivering great activity for efficient light-driven H 2 O 2 production. The specific challenges and opportunities related to photocatalytic materials discovery and development that will emerge from this important field are discussed.

Wide-band gap perovskite with adjustable band gaps can be integrated with organic solar cells to form tandem solar cells (TSCs), thereby surpassing the Shockley–Queisser limit. However, increasing Br content to elevate the band gap above 1.8 eV complicates crystallization, leading to inferior film quality and defects due to the unmanageable evolution of intermediate phases. Surface passivation improves crystallization but hard to moderate the inhomogeneous component distributions and defects in the bulk phase. Here, we introduce a diammonium salt as an additive to regulate the homogeneity and crystallization of perovskite film, eliminating the low-dimensional intermediate phase for orientated crystallization of 1.85 eV perovskite, resulting in efficient wide-band gap perovskite solar cells with an impressive open-circuit voltage ( V oc ) of 1.379 V and operational stability remaining 85 % of their initial efficiency after illumination for 1200 h. Furthermore, perovskite-organic TSCs achieve a champion power conversion efficiency of 24.03 % and a high V oc of 2.108 V, one of the highest V oc for perovskite-organic TSCs.

Efficient dual-single-atom catalysts are crucial for enhancing atomic efficiency and promoting the commercialization of fuel cells, but addressing the sluggish kinetics of hydrogen oxidation reaction (HOR) in alkaline media and the facile dual-single-atom site generation remains formidable challenges. Here, we break the local symmetry of ultra-small ruthenium (Ru) nanoparticles by embedding cobalt (Co) single atoms, which results in the release of Ru single atoms from Ru nanoparticles on reduced graphene oxide (Co 1 Ru 1,n /rGO). In situ operando spectroscopy and theoretical calculations reveal that the oxygen-affine Co atom disrupts the symmetry of ultra-small Ru nanoparticles, resulting in parasitic Ru and Co dual-single-atom within Ru nanoparticles. The interaction between Ru single atoms and nanoparticles forms effective active centers. The parasitism of Co atoms modulates the adsorption of OH intermediates on Ru active sites, accelerating HOR kinetics through faster formation of *H 2 O. As anticipated, Co 1 Ru 1,n /rGO exhibits ultrahigh mass activity (7.68 A mg Ru −1 ) at 50 mV and exchange current density (0.68 mA cm −2 ), which are 6 and 7 times higher than those of Ru/rGO, respectively. Notably, it also displays exceptional durability surpassing that of commercial Pt catalysts. This investigation provides valuable insights into hybrid multi-single-atom and metal nanoparticle catalysis.

Marine corrosion has been a global problem with the damage on environment, and economy. With the development, traditional coating technology is difficult to meet the current demands of applications. In this study, TiO 2 nanoparticles were modified and dispersed in silicone oil to form TiO 2 nanofluid. And, the nanofluid was infused into hierarchical structure to produce the SLIPS which is obtained by spraying with the solution of Al 2 O 3 , which significantly reduce the lubricant leaching. As synthesized coating shows the good performance in corrosion resistance. The coating prepared by this novel method show the great potential applications in different marine environments.

Direct electrochemical seawater splitting is a renewable, scalable, and potentially economic approach for green hydrogen production in environments where ultra-pure water is not readily available. However, issues related to low durability caused by complex ions in seawater pose great challenges for its industrialization. In this review, a mechanistic analysis of durability issues of electrolytic seawater splitting is discussed. We critically analyze the development of seawater electrolysis and identify the durability challenges at both the anode and cathode. Particular emphasis is given to elucidating rational strategies for designing electrocatalysts/electrodes/interfaces with long lifetimes in realistic seawater including inducing passivating anion layers, preferential OH − adsorption, employing anti-corrosion materials, fabricating protective layers, immobilizing Cl − on the surface of electrocatalysts, tailoring Cl − adsorption sites, inhibition of OH − binding to Mg 2+ and Ca 2+ , inhibition of Mg and Ca hydroxide precipitation adherence, and co-electrosynthesis of nano-sized Mg hydroxides. synthesis methods of electrocatalysts/electrodes and innovations in electrolyzer are also discussed. Furthermore, the prospects for developing seawater splitting technologies for clean hydrogen generation are summarized. We found that researchers have rethought the role of Cl − ions, as well as more attention to cathodic reaction and electrolyzers, which is conducive to accelerate the commercialization of seawater electrolysis.

Thermoelectric technologies based on Seebeck and Peltier effects, as energy techniques able to directly convert heat into electricity and vice versa, hold promise for addressing the global energy and environmental problems. The development of efficient and low-cost thermo- electric modules is the key to their large-scale commercial applications. In this paper, using a non-equilibrium laser 3D printing technique, we focus an attention on the fabrication of mid-temperature p-type SnTe thermoelectric materials. The influence of laser power, scanning speed and layer thickness on the macro-defects, chemical and phase composition, microstructure and thermoelectric performance was systematically investigated. First and foremost, the processing parameter window for printing a highquality layer is determined. This is followed by the finite element method used to simulate and verify the influence of the laser-induced molten pool temperature distribution on the final composition and microstructure. Finally, the high-performance SnTe layer with 10 mm × 10 mm in area is produced within seconds with room temperature Seebeck coefficient close to that of SnTe manufactured by the traditional methods. Consequently, this work lays a solid foundation for the future fabrication of thermoelectric modules using laser non-equilibrium printing techniques.

Hydrogen (H) retention in tungsten (W), a critical challenge for its application as a plasma-facing material in nuclear reactors, is strongly influenced by grain boundaries (GBs). However, the precise role of GB in H diffusion and retention, as along with the intricate interactions with H energetics and kinetics, remains poorly understood and contentious yet. In this study, we conduct comprehensive atomistic simulations to explore the effects of GBs on H segregation, desorption, and diffusion in W. Our results reveal that GBs preferentially trap H, with the GB-H binding energies closely related to specific polyhedral structural units. We thoroughly analyze the migration pathways and energy barriers involved in H desorption, determining the critical desorption and decoupling temperatures using a statistical approach. More importantly, the rapid H diffusion channels are identified within GBs that contain discrete dislocation cores and pentagonal bipyramid (PBP) units. Based on these results, we propose a material design strategy that involves tuning GB types and temperature conditions to mitigate H retention. These findings provide essential insights into the energetics and kinetics of GB-H interactions, offering valuable guidance for the design of W-based materials with enhanced resistance to H retention through GB engineering.
