Insight into the Balancing Effect of Active Cu Species for Hydrogenation of Carbon-Oxygen Bonds
TL;DR: In this paper, a series of highly comparable Cu/SiO2 catalysts were investigated for hydrogenation of carbon-oxygen (C-O) bonds and the results showed that when the accessible metallic Cu surface area is below a certain value, the catalytic activity of hydrogenation linearly increases with increasing Cu0 surface area, whereas it is primarily affected by the Cu+ surface area.

Synthesis of Ethanol via Syngas on Cu/SiO2 Catalysts with Balanced Cu0–Cu+ Sites
TL;DR: Characterization results indicated that the Cu(0) and Cu(+) were formed during the reduction process, originating from well-dispersed CuO and copper phyllosilicate, respectively, and it is shown that the selectivity for ethanol or ethylene glycol can be tuned simply by regulating the reaction temperature.
