Abstract:Multi-walled carbon-nanotubes (MWCNTs) are drawing increasing attention in recent years. This material possesses a series of unique features, such as its nanometer-sized channel, highly conductive graphitized tube-wall, sp 2-C-constructed surface, and excellent performance for adsorption and spillover of hydrogen, which make the MWCNTs full of promise to be a novel catalyst support or promoter. This article will review the recent progress in applied research of MWCNTs as a novel promoter in heterogeneous catalysis for active components, including metals and their oxides, with the emphasis on the study and development of MWCNT-promoted catalysts related to CO/CO2 hydrogenation to alcohols and dimethyl ether based on the recent works carried out in our laboratory.
Keywords:Multi-walled carbon nanotube-promoted catalysts  Co–  Cu catalysts  Co–  Mo–  K catalysts  Cu–  ZrO2 catalysts  Pd–  ZnO catalysts  Higher alcohol synthesis  CO2 hydrogenation
