Summary: In this study, a Fe-based BaCe0.5Fe0.5O3-delta (BCF5050) membrane was used to simultaneously produce pure nitrogen and syngas by coupling air separation with oxy-CO2 reforming. By introducing a porous layer and Ni/Al2O3 on the methane side of the membrane, oxygen removal from air was significantly enhanced, resulting in higher nitrogen purity. This led to constant production of nitrogen with a purity over 99.3% and high CH4 and CO2 conversion rates during the 140-hour test period on the other side of the membrane.

Summary: The aim of this study was to design nanocatalysts with enhanced anti-coke ability, high catalytic activity and stable performance for the oxidative conversion of CH4/CO2 mixture to syngas. NiAl2O4, WNiAl2O4, and CoWNiAl2O4 nanocatalysts were fabricated using sol-gel technique, and plasma treatment was utilized to enhance the performance of CoWNiAl2O4. The results showed that the addition of tungsten improved the rate of coke gasification and stability of the NiAl2O4 nanocatalyst, while the catalytic activity of WNiAl2O4 was lower due to active sites coverage. Cobalt addition was made to compensate for the reduction of catalytic activity, resulting in smaller particle size and uniform dispersion. However, the sol-gel prepared CoWNiAl2O4 showed higher coke deposition and deactivation. The plasma-enhanced sol-gel fabricated CoWNiAl2O4 exhibited excellent dispersion, fine particle size, strong metal-support interaction, and high surface area, leading to a X-CH4 of 92% at 850 degrees C. A well-maintained structure and excellent dispersion were observed after 48 h TOS.

Summary: By functionalizing the surface of a Cu/ZnO catalyst with stearic acid, the hydrophobicity of the catalyst is significantly enhanced while maintaining its structure and catalytic performance almost unchanged. The hydrophobic Cu/ZnO catalyst shows positive inhibitory effects on the water-gas shift reaction in one-step DME synthesis. The improved catalytic performance demonstrates the importance of surface hydrophobicity in heterogeneous catalysts.

Summary: Hierarchical Nb2O5 microspheres with abundant oxygen defects were synthesized to anchor Pd species, promoting electron transfer between Pd and Nb species to form interfacial Pd-NbOx sites. The electron-withdrawing effect of Nb species thinned the electron density of Pd species, beneficial for activating adsorbed CO molecules and enhancing catalytic activity. The Pd/H-Nb2O5 catalyst showed high CO conversion and DMO selectivity, with improved catalytic stability achieved through boosting interfacial electron interaction via oxygen defects induction.

Summary: This study investigated the permeation of binary and ternary H2-containing mixtures through a SAPO-34 membrane and examined the influence of hydrogen and the other gases (CO2 and CH4) on permeability and selectivity. The research employed a validated mass transport model based on surface and gas translation diffusion to analyze the behavior of gas mixtures at different temperatures, feed pressures, and compositions. The results showed that CO2 and CH4 in the H2-containing mixtures reduced the permeability of H2 by about 80% due to their stronger adsorption, while H2 promoted the permeation of CO2 and CH4. The study demonstrated the potential of SAPO-34 membranes in treating H2-containing mixtures.

Summary: In recent decades, membrane-based processes have been widely used in various industrial processes. Membrane distillation, a thermally driven separation process, allows only vapor molecules to transfer through a microporous hydrophobic membrane. Wetting and temperature polarization negatively affect the performance of membrane distillation, but advanced membranes have been developed to overcome these issues. This review focuses on the basic concepts, membrane properties, and advances in membrane materials associated with membrane distillation. It also discusses the use of photothermal materials for solar-driven membrane distillation applications.

Summary: Developing highly efficient bifunctional oxygen electrocatalysts is crucial for zinc-air flow batteries. Metal-organic frameworks (MOFs) and covalent organic polymers (COPs) have emerged as promising alternatives due to their designable and controllable atomic-level structures. However, their catalytic performances are limited by conductivity and catalytic activity. In this study, nanosheet FeNi-MOF and iron phthalocyanine rich COP hybrid materials are assembled through the pi-pi stacking effect to create highly efficient bifunctional electrocatalysts. The resulting catalyst exhibits superior catalytic performance and stability, making it a promising candidate for zinc-air flow batteries.
