Study of Rhodium-based Catalysts for the Synthesis of C_2-oxygenates from Syngas

As one of the alternative methods for preparing clean fuels and raw chemicals from non-petroleum sources,the catalytic conversion of syngas derived from coal,natural gas and biomass to C2-oxygenates such as alcohol,acetaldehyde and acetic acid has attracted great attention.Rhodium-based catalyst is one of the most effcctive catalytic system for the synthesis of C2-oxygenates from syngas.The recent studies of rhodium-based catalysts mainly including promoters,supports and preparation methods and conditions for synthesis of C2-oxygenates from syngas were reviewed.The perspective for further study was presented.
