摘要: Abstract The research was designed to synthesize novel single-atom silver-manganese nanocatalysts with a simple method for producing highly demanded ethyl glycolate (EGly) and acetaldehyde diethyl acetal (ADA) by hydrogenating bioresources-derivable oxalate (DEO) under different temperatures. DEO conversions achieved the catalyst are 80–100%. 100% EGly or 97% ADA selectivity produced simply tuning reaction were formed through entrance of Ag atoms into lattice tunnels hollandite-type manganese oxide (HMO) H2 reduction at 200 °C. excellent activities mainly ascribed activation desirable chemical adsorption ethanol. first order hydrogenation DEO, while obtained via hydrogenation, dehydration reaction. With help high-efficiency nanocatalysts, bioresources promising raw materials various high-value chemicals in environmentally responsible manners.
