Chinese researchers design new catalyst to produce acetaldehyde from ethanol

In China, a new catalyst design could transform how acetaldehyde is made from renewable bioethanol. Researchers from the Dalian Institute of Chemical Physics, Chinese Academy Sciences found that a carefully balanced mix of gold, manganese, and copper creates a powerful synergy that boosts efficiency while lowering operating temperatures. Their best catalyst achieved a 95% yield at just 225°C and stayed stable for hours. The discovery points to a cleaner, more sustainable path for producing key industrial chemicals.
