Summary: In this study, we presented a facile strategy for modulating the local concentration of CO using polymer coating, which led to selective, active, and stable production of acetate on a Cu model-catalyst. The fluorinated polymer coating enhanced CO diffusion and increased the hydrophobicity of the catalyst layer, resulting in significantly improved acetate selectivity and partial current density on the Cu-catalyst.

Summary: In this study, the mechanisms and metal-oxide interactions of In2O3-supported Ni catalysts in CO2 hydrogenation were investigated. It was found that Ni clusters exhibited cationic states at low coverages, and the chemical bonding and electron transfer at the Ni/In2O3 interface were crucial for the activation of H2 and CO2. Additionally, reaction intermediates were easily formed and desorbed under CO2 hydrogenation conditions. These findings are important for the rational design of efficient In2O3-based catalysts.

Summary: Different porous TiOx electrodes were synthesized to study the effect of their porous structure on the efficiency of electrocatalytic phenomena in removing organic pollutants from water. It was found that small pore electrodes had lower reaction rates in stirred-tank reactor, while larger pore electrodes with coarse roughness were beneficial. However, small pore electrodes allowed for optimal mass transport in flow-through configuration.

Summary: In this study, a low-temperature de-NOx catalyst with strong H2O tolerance was developed through methyl functionalization. The catalyst showed only a slight decrease in NOx conversion when 6% H2O was introduced at low temperature. The elimination of small pore size and diminished H2O adsorption energy due to methyl functionalization were found to be the key factors behind the improved H2O tolerance.

Summary: A bended ribbon biomass particle model was developed to investigate the transport properties inside a riser reactor. The residence time distribution (RTD) of particles was analyzed using the Eulerian-Lagrange method. The study examined the effects of sampling height, particle density, particle size, and gas-to-solid mass ratio on the RTD. The results showed that ribbon biomass particles exhibited a typical annular-core spatial distribution during transportation. The RTD of particles followed an approximate single-peaked normal distribution, with the mean residence time reaching up to 0.7 s for particles with a density of 1200 kg/m3. The flow patterns approached plug flow when the particle length exceeded 12 mm. The study also highlighted the significant impact of the gas-to-material mass ratio on the particle flow pattern.
