Summary: An effective symmetric structured dual phase mixed conducting oxygen separation membrane made of 60 wt% Ce0.9Gd0.1O2-delta - 40 wt% Ba0.5Sr0.5Co0.8Fe0.2O3-delta (60CGO-40BSCF) was prepared using aqueous tape casting. The membrane consisted of a dense thin layer in the middle and porous substrates on the two sides. This structure optimized both oxygen ion diffusion and surface gas exchange, resulting in increased oxygen permeation flux. Compared to a monotonous dense membrane, the porous supported symmetric membrane exhibited higher permeation fluxes. The study indicates that the porous supported symmetric membrane structure is an efficient strategy to enhance oxygen permeation flux.

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 traditional Haber-Bosch process for ammonia synthesis is energy-intensive and causes nitrate pollution. A sustainable and moderate nitrate electrocatalytic reduction to ammonia (NO3RR) was used to convert waste into a valuable resource. Co3O4 showed the best NO3RR performance among spinel cobalt-based catalysts, and a Co3O4/Co catalyst with a unique nanosheet structure was fabricated. The catalyst exhibited excellent NO3RR properties in a neutral electrolyte and could be used in a continuous flow electrolyzer to significantly increase ammonia production.

Summary: Accurate prediction of catalytic performance based on DFT calculation is crucial for nitrogen fixation. However, current computational methods ignore the effects of electrode potential and solvation, resulting in large deviations between predicted and measured potentials. This study proposes an external iteration method and a hybrid solvent model to account for these effects, achieving good agreement between theoretical and experimental potentials. These findings have important implications for prediction of other electrocatalytic systems.
