Wheat straw is a kind of rich agricultural waste. Resource utilization of wheat straw has received widespread attention. Herein, a novel approach of the rapid reduction of Ag2O into Ag by wheat straw with the production of organic acids under mild hydrothermal conditions is reported. After parameter optimization, almost all Ag2O is converted to Ag at a mild reaction temperature of 150 ℃ and a reaction time of 60 min in sodium hydroxide solution. Meanwhile, wheat straw was converted to organic acid such as formic acid, lactic acid, and acetic acid. This offers a cost-effective approach for Ag recovery and resource utilization of biomass.
