Activity Boost for Cobalt–Selectivity Shift and Activation During CO2 Methanation by Carbon Nitride‐Modified Al2O3 Support

ChemCatChem, EarlyView.
Alumina is modified with carbon nitride (CN@Al2O3) to intensify interaction of the support with the active phase during CO2 methanation. For this, CN@Al2O3 and bare Al2O3 are decorated with separately synthesised Co3O4 nanoparticles. Modification by CN stabilizes the nanoparticles, facilitates reduction, and results in an activity boost as well as ...

Enhanced Photocatalytic Activity of NH3‐SCR on Sulfur‐Doped TiO2 (101) Surface

ChemCatChem, EarlyView.
S‐doped TiO2 (101) shows enhanced activity in the selective catalytic reduction of NO with NH3 (NH3‐SCR) compared to pristine TiO2. Density functional theory (DFT) calculations reveal that sulfur‐doping modifies the electronic structure and lowers the energy barrier for each step. Abstract Photo‐assisted NH3 selective catalytic reduction (photo‐NH3‐SCR)

Valorization of Glycerol Through 2,2,6,6‐Tetramethyl‐1‐Piperidine‐N‐Oxyl (TEMPO)‐Catalyzed Electrochemical Oxidation with High C3 Product Selectivity: Impact of Stirred Bulk Versus Flow Electrolysis

ChemElectroChem, EarlyView.
2,2,6,6‐tetramethyl‐1‐piperidine‐N‐oxyl‐catalyzed glycerol electrochemical oxidation proceeds with different selectivity when comparing bulk stirred and flow electrolysis. Conversion of glycerol to value‐added products is an attractive solution to the oversupply of this byproduct of biofuel production.

Probing the Effect of Spectator Anions on Chloride Adsorption for Selective Oxygen Evolution Reaction over Ni Catalysts

ChemElectroChem, EarlyView.
After the oxidation of Ni(OH)2, chloride ions adsorb on the NiOOH surface, leading to OCl− formation through the chlorine oxidation reaction and partial Ni dissolution. In contrast, the presence of a spectator anion layer on NiOOH inhibits chloride adsorption and improves the selectivity of the oxygen evolution reaction.

Recent Advances in Tailoring Active Site Microenvironments of Fe–N–C Catalysts for Oxygen Reduction

ChemistryEurope, EarlyView.
This review summarizes the main factors affecting Fe–N–C catalysts for ORR: activity depends on active site structure, electronic configuration, and porosity, while stability is limited by metal leaching, carbon degradation, and inactive phase formation.

Oxide Interface of Gallium‐Based Liquid Metals: Beneficial Bridge or Hidden Risk?

ChemistryEurope, EarlyView.
Discussion on oxide interfaces in gallium‐based liquid metals have concentrated on their properties, behaviors, and related applications. However, the molecular mechanisms underlying effects, as well as the differences between the presence and absence of the oxide layer, have been less thoroughly discussed.
