The practical applications of rechargeable lithium metal batteries (LMBs) are largely limited by the severe lithium dendrites and safety related issues caused by the use of flammable organic liquid electrolytes. To address these critical issues, the development of solid-state electrolyte for LMBs become critically important. Herein, we report a solid-state electrolyte based on N, P, S tri-doped holey carbon (NPS-HC) incorporated with poly(ethylene oxide)/polyvinyl pyrrolidone polymer (NPS-HC/PEO-1) and LiNO 3 as addition. The NPS-HC/PEO-1 electrolyte exhibits high ionic conductivity of 2.7 × 10 -4 S cm -1 at 80 °C, high Li + transference number of 0.77, and high voltage stability over 4.65 V. The symmetric Li||NPS-HC/PEO-1||Li cell using the NPS-HC/PEO-1 electrolyte can display a long cycling life over 2220 h at 0.05 mA cm -2 at 80 °C, and a high critical current density of 0.9 mA cm -2 . When the electrolyte was assembled in the asymmetric Li||NPS-HC/PEO-1||LiFePO 4 cell, the cell delivered a high reversible capacity of 159.2 mAh g -1 at 0.1 C. At 1 C, the cell also retained a high reversible capacity of 90.0 mAh g -1 after 700 cycles with an initial capacity retention of 74.3%. © 2022, The Authors. All rights reserved.

Micro-Mesoporous Graphitized Carbon Fiber as Hydrophobic Adsorbent that Removes Volatile Organic Compounds from Air

Activated carbon fibers (ACFs) are a popular class of adsorbents for volatile organic compounds (vocs), however, their abundant hydrophilic functional groups greatly limit their selective adsorption capacity for organics under humid conditions. In this work, porous graphitized carbon fibers (PGCFs) with enhanced hydrophobicity were prepared by KOH-promoted catalytic graphitization of viscose-based ACF, and their adsorption capacity for representative vocs was investigated. Characterizations showed that the PGCFs had reduced O/C ratios, high specific surface areas exceeding 2200 m2/g, and micro-mesoporous structure. Under dry conditions, the adsorption capacity of a typical PGCF for toluene, cyclohexane and ethanol reached 7.2, 4.6 and 2.0 mmol/g, respectively. At 80% relative humidity, the adsorption capacity for toluene and cyclohexane retained 92% and 85%, respectively, while that for ethanol even increased by 54%. The abundant π electrons and high polarizability of the PGCF strengthened the π-π interaction and dispersion force with non-polar organics, thereby enhancing their removal. The capillary condensed water in mesopores could act as absorbate for the uptake of polar ethanol under humid conditions. The toluene-adsorbed PGCF was effectively regenerated at a low temperature of 80°C. Benefiting from their excellent adsorption capacity and moisture-resistance, PGCFs may be promising adsorbents to remove vocs from air. © 2022, The Authors. All rights reserved.

Traditional Ni-based catalysts for Dry Reforming of Methane (DRM) suffer from poor stability due to carbon deposition. In this study, we developed a Ni/ZrO 2 catalyst prepared by using a sol–gel method, which presents strong resistance to carbon depositions. Additionally, the metal Ga was introduced to Ni/ZrO 2 , which effectively enhanced the catalytic activity for DRM reaction as compared to the Ni/ZrO 2 . The catalysts were characterized by various techniques, including TPSR, XRD, TPR, XPS, TPD, TG, Raman, and EPR. Characterization results revealed that the addition of Ga enhanced the metal-support interaction, promoting the activation of reactant molecules by reducing the activation energy of the DRM reaction. Further investigation showed that because of the introduction of metal Ga, a large number of oxygen vacancies were fabricated, significantly increasing the CH 4 conversion. Stability test indicated that the representative NiGa/ZrO 2 catalyst exhibited a long-term life span in the DRM reaction for 250 h, without catalyst deactivation due to the slight carbon deposition with 1.93 wt%.

Zirconium-based metal–organic frameworks (Zr-MOFs) have emerged as a promising candidate for efficiently eliminating toxic chemicals under ambient conditions. Herein, we demonstrate the remarkable ammonia capture capabilities of the hierarchically porous MOF-808 xerogel (G808) macrostructure and its amino-functionalized analogue (G808-NH2), which were constructed through a sol–gel-based strategy combined with convenient ambient pressure drying. Static isotherm measurements and dynamic breakthrough tests using engineered Zr-MOF xerogel granules were conducted to illuminate the thermodynamic and kinetic characteristics for ammonia sorption. The G808 and G808-NH2 xerogels manifest substantially higher ammonia uptake, intensified interfacial interactions, and enhanced irreversible retention toward ammonia compared with the state-of-the-art activated carbon-based materials, particularly at the low-concentration region. Moreover, these hierarchical Zr-MOF nanoarchitectures exhibit extraordinary ammonia removal performance as well as excellent environmental robustness under simulated respirator canister/protection filter circumstances, with the breakthrough capacities of G808-NH2 being individually more than two and one orders of magnitude greater than those for the pristine and metal-amine impregnated carbons. The kinetic ammonia adsorption behaviors can be well delineated by the pseudo-first-order Wheeler-Jonas model. An in-depth discussion on the ammonia sorption regime, detailing five binding patterns besides reversible physisorption with a special focus on the impacts of polar amino groups and humidity, was proposed based on multiple characterizations and Grand Canonical Monte Carlo simulation. © 2022, The Authors.

Efficient catalytic destruction of light alkane with ultra-stable and highly symmetric structure is still an intractable issue. High entropy oxides (HEOs) with high chemical disorder and lattice distortion and superior stability have shown great potential in heterogeneous thermocatalysis. Herein, spinel-type HEOs are synthesized via a scalable co-precipitation method with different precipitants (NaOH, Na2CO3, and NaHCO3) and firstly adopted in catalytic destruction of propane. Results demonstrate that the HEO-NaOH possesses the best activity, achieving 90% of propane conversion at 325 °C with an apparent activation energy of 56 kJ·mol-1. Compared with other two HEOs, HEO-NaOH system has larger quantities of surface oxygen vacancies and easily forming several reactive oxygen species (OOH-, O2-, and OH-, etc.), which significantly contribute to the catalytic performance. Moreover, the excellent water resistance of HEOs is verified due to their high conformational entropy and structural stability. Reaction mechanism reveals that OOH- and O2- are the key species in the oxidation of C3H8, which break C-H and C-C bonds in sequence, and are then converted to oxygenated compounds via oxygen oxidation before the final mineralization. The present work provides new insights into the fabrication of efficient catalysts for light alkane destruction as well as other thermocatalytic applications. © 2023, The Authors.
