Abstract: The catalysts in which rare earth metal oxide is added for hydrogen production from ethanol steam reforming are summarized. The study of catalysts for ethanol steam reforming is reviewed. Three kinds of rare earth metals oxide CeO2，Y2O3 and La2O3 used frequently at present are compared，and their different functions are discussed. The research direction in the future is presented according to the latest research progress.
