Research Progress of Catalysts for Hydrogen Production Using Low-temperature Bioethanol Steam Reforming
Bioethanol steam reforming(BESR)reaction is a promissing route of hydrogen production.The hydrogen-efficiency from BESR reaction is closely related with the nature of catalysts and reaction temperature.Usually the high temperature could increase the catalytic activity of catalysts,however it is easy to deactivate the catalyst due to sintering and increase the energy consumption,therefore developing low-temperature and high-efficiency catalysts for BESR reaction is the focus of current research.Herein,the research progress in the studies of the catalysts for BESR reaction at low temperature was reviewed.Firstly,the categories of catalysts,including monometal-supported catalyst,bimetal-supported catalyst and composite catalyst were introduced;secondly,the factors that influenced the activities of the catalysts were summarized,in additon to the type of active compounts,the nature of supports,the chemical state of active catalytic centers and metal-support interatction all had significant effects on the acyivities.The review provides reference value for the systematic understanding of catalysts for BESR at low temperature.
