Abstract While the precise design of catalysts is one ultimate goals in catalysis, practical strategies often fall short, especially for complicated photocatalytic processes. Here, taking hydrogen evolution reaction (HER) as an example, we introduce a theoretical approach designing robust metal cocatalysts supported on TiO 2 using density functional theory calculations adopting on-site Coulomb ...

Abstract Due to the important role of cocatalyst in polymerization process employing industrially favored Ziegler–Natta catalysts, its effect on kinetic behavior, catalyst activity, and polymer properties is discussed. In this paper, triethyl aluminum (TEA) triisobutyl (TIBA) have been used as main ingredient with 10–20 mol percent diethyl chloride (DEAC) ethyl dichloride (EADC) cocatalysts, be...

Photocatalytic H2O2 evolution has received extensive attention as an environmentally friendly method, which is a dynamic process of formation and decomposition. At present, researches mainly focus on the formation, while decomposition rarely studied. In addition, platinum cocatalyst plays important role in enhancing photocatalytic activity, but effects valence state especially towards decomposi...

Using a series of ordered mesoporous TiO2 (om-TiO2) with and without Ce or Cu doping, the effects structure, metal doping residual template species in structure are systematically evaluated terms products formed during CO2 photoreduction process. It is found that contributes significantly hydrogen evolution reaction from splitting gaseous water. No cocatalyst was needed to achieve high yields. ...
