Abstract
Direct photoproduction of hydrogen and 1,2-propanediol from aqueous me thanol and ethanol solution, catalysed by ZnS, has been achieved. Trea tment of the catalyst and the reaction temperature have an important i nfluence on the selectivity of the desired product. Alpha-alpha radica l cross coupling of .CH2OH and .CHOHCH3 has been proposed to lead to t he formation of 1,2-propanediol. Electron transfer, aldehyde addition reaction and hydrogen atom abstraction also lead to 1,2-propanediol fo rmation.
