The practical application of splitting water to generate hydrogen is to a large extent hindered by an oxygen evolution reaction (OER) process. Electrocatalysts with low-cost, high activity, and durability are essential for the low kinetic threshold of the OER. Despite the high active performances of noble metal compound electrocatalysts like IrO2 a...
SiO2-modified gamma-Al2O3 by chemical liquid deposition (CLD) was developed as a catalyst support for use in the aldol condensation of methyl acetate with formaldehyde to produce methyl acrylate. Cs/Al2O3 and Cs/Si-Al2O3 catalysts synthesized by incipient-wetness impregnation were characterized, and catalytic performance was evaluated. A correlatio...

Metal nanoparticle (NP) sintering is a prime cause of catalyst degradation, limiting its economic lifetime and viability. To date, sintering phenomena are interrogated either at the bulk scale to probe averaged NP properties or at the level of individual NPs to visualize atomic motion. Yet, "mesoscale" strategies which bridge these worlds can chart...
Hydrogen generation by metal-free photocatalysts and electrocatalysis of H2O is currently deemed as one of the most innovative and challenging routes to obtain sustainable green energy. Due to the high tunability, ionic liquids are expected to be new generation catalysts for H-2 production. In this work, for the first time, the dynamic behavior of ...

Improving the platinum (Pt) mass activity for low-cost electrochemical hydrogen evolution is an important and arduous task. Here, a selective etching-reducing fluidized bed reactor technique is reported to create Ti vacancies and firmly anchor single Pt atoms on the active {100} facets of titanium carbide (TiC) to increase the Pt utilization effici...

The halide anions present in the electrolyte improve the Faradaic efficiencies (FEs) of the multi-hydrocarbon (C2+) products for the electrochemical reduction of CO2 over copper (Cu) catalysts. However, the mechanism behind the increased yield of C2+ products with the addition of halide anions remains indistinct. In this study, we analysed the mech...
