Electrochemical CO2 reduction (CO2R) in acidic media with Cu-based catalysts tends to suffer from lowered selectivity towards multicarbon products. This could principle be mitigated using tandem catalysis, whereby the *CO coverage on Cu is increased by introducing a CO generating catalyst (e.g. Ag) close proximity. Although this has seen significant success neutral/alkaline media, here we repor...

Abstract The controllable synthesis of oxygen evolution reaction (OER) electrocatalyst is an urgent need to advance the development sustainable energy conversion and storage. However, OER efficiency in acidic media seriously hindered by slow kinetics. traditional electrocatalysts are more prone be oxidized corroded as results unstable carrier structures variable electronic states active species...

Recently, the extraction of Au(III) using series aliphatic ketones in hydrochloric acid media has been investigated detail. The present study describes behaviors a aromatic ketones, which never reported. Aromatic with shorter alkyl side chains showed higher extractability. rapid and capacity were comparable to industrial extractant dibutyl carbitol (DBC). except acetophenone, are less soluble w...
