Graphitic carbon nitride (g-C3N4) has garnered significant interest in photocatalytic technology for addressing energy crisis and environmental pollution, owing to its remarkable structural stability and photocatalytic properties. Nevertheless, the photocatalytic performance of g-C3N4 is limited by its low efficiency in carrier separation. This study synthesizes Na and K co-doped g-C3N4 hollow spheres (NaK-CN) with an ultra-thin shell through high-temperature calcination, substantially improving its photocatalytic activity in hydrogen production from water splitting. The photocatalytic hydrogen production efficiency of NaK-CN reaches 4502 μmol h−1 g−1, which is five times that of the original g-C3N4 hollow sphere. This significant improvement is attributed to the formation of intralayer Na-N and interlayer K-N bonds, which enhances carrier separation and transfer within and between the layers, as evidenced by DFT calculations and ultrafast transient absorption (TA) spectroscopy. The results demonstrate that the creation of a 3D carrier transport network by Na and K doping at different crystallographic sites significantly improves the photocatalytic activity of C3N4 and introduces a novel strategy for developing highly efficient photocatalysts. © 2025, The Authors.

Due to the greenhouse effect caused by carbon dioxide (CO2) emission, much attention has been paid for the removal of CO2. Porous liquids (PLs), as new type of liquid materials, have obvious advantages in mass and heat transfer, which are widely used in gas adsorption and separation. Metal–organic frameworks (MOFs) with the merit like large surface area, inherent porous structure and adjustable topology have been considered as one of the best candidates for PLs construction. This review presents the state-of-the-art status on the fabrication strategy of MOFs-based PLs and their CO2 absorption and utilization performance, and the positive effects of porosity and functional modification on the absorption-desorption property, selectivity of target product, and regeneration ability are well summarized. Finally, the challenges and prospects for MOFs-based PLs in the optimization of preparation, the coupling of multiple removal techniques, the in situ characterization methods, the regeneration and cycle stability, the environmental impact as well as expansion of application are proposed. © 2025 Institute of Process Engineering, Chinese Academy of sciences

We report a fabrication method for addressing the non-uniform arrangement issues associated with the asymmetric tapered fiber bundles (TFBs) in high-power pump and signal combiners (PSCs), which do not require pre-treatment of the pump fibers. It employs a homemade thin-walled glass tube with the coating layer, and six pump fibers surround it evenly to collectively form the TFB, while the signal fiber remains unaffected during the tapering process of the fiber bundle. The 3D simulation model of the backward (6 + 1)×1 PSC was established by the refractive index distribution method to calculate the transmission efficiency of the pump light and signal light, and then identify the optimal preparation parameters for achieving the best efficiency. In this model, a simulated quasi-uniform energy distribution light field was used as the input of the pump fiber, which can optimize the previous calculation method. Experimental results exhibited that the backward (6 + 1)×1 PSC achieved signal light and pump light transmission efficiencies of over 96% and 98%, respectively, the beam quality degradation is ∆M2 = 0.09, and the total output pump power was 4.102 kW. The experimental results are in good agreement with the simulation results. © 2025 Optica Publishing Group under the terms of the Optica Open Access Publishing Agreement.

Multifunctional integration is an essential feature to broad the practical application of artificial super-hydrophobic coating in numerous fields. Herein, a passive anti-icing and active photo-thermal deicing super-hydrophobic coating with excellent mechanochemical durability, self-healing and long-term corrosion protection performances has been developed by a facile and environmentally friendly heterogeneous hybrids approach. The prepared coating exhibits excellent super-hydrophobicity with CAs up to 161.9°, SAs is only 4.2° and the adhesive force value of microdroplets is ∼16.8 ± 0.6 μN. The composite coating holds its prominent water repellency even after various extreme treatments, including high-low temperature alternation, 60 meters sandpaper abrasion, kneading stability and corrosive medium immersion. Moreover, the coating also presents remarkable self-cleaning properties both in air or oil even after mechanical abrasion and significantly healable capabilities against O2 plasma etching. Furthermore, the influence mechanism of the heterogeneous hybridization on thermal property and corrosion resistance of the coating were systematically analyzed. In addition, utilizing the superior water repellency and the photo-thermal conversion performances, the coating could efficiently delay the freezing time and active deicing after 808 nm NIR laser irradiate. Therefore, the multifunctional integrated super-hydrophobic coating will be promising for several industrial fields. © 2022, The Authors. All rights reserved.

Photoelectrocatalytic technology (PEC) is an emerging green and sustainable technology for treating antibiotic wastewater. However, its effectiveness is limited by the recombination of photogenerated carriers. To address this issue, the Fenton reaction, an advanced oxidation process, can be coupled with PEC technology to enhance the oxidative degradation of antibiotic wastewater. This research involved creating a Zn 0.5 Ni 0.5 Fe 2 O 4 /silicon nanowires (SiNWs) Z-type heterojunction through the spin coating technique, which was then utilized in the PEC coupled Fenton reaction to break down antibiotic wastewater. The inherent electric field and the voltage applied hastened the segregation of e − and h + within the system. These advantages make the Zn 0.5 Ni 0.5 Fe 2 O 4 /SiNWs heterojunction highly efficient in removing various antibiotics, including tetracycline (TC), ciprofloxacin (CIP), amoxicillin (AMX), and levofloxacin (LVX). In particular, the Zn 0.5 Ni 0.5 Fe 2 O 4 /SiNWs heterojunction demonstrated an 82.21% degradation efficiency for TC, exhibiting a kinetic constant ( k ) of 0.02688 min −1 , a rate 2.82 times (4.80 times) greater than that of SiNWs. Experimental findings reveal that Zn 0.5 Ni 0.5 Fe 2 O 4 /SiNWs exhibit superior light absorption properties and a reduced rate of photogenerated charge recombination. The doping of Zn 0.5 Ni 0.5 Fe 2 O 4 effectively improves the catalytic performance of SiNWs. This research offers fresh insights into researching PEC-coupled Fenton reaction methods for the degradation of antibiotics and paves the way for advancing the creation of more potent photoelectrochemical catalysts in the future.
