摘要
Abstract
There is great significance to produce C2-oxygenates such as ethanol via syngas from coal, natural gas or biomass from practical and academy of view; and supported Rh-based catalysts are the most effective for this conversion. The choice of promoter is critical for obtaining high-performance catalysts, of which Fe, Mn, and Li are most widely used. The effects of promoters have been studied extensively and comprehensively, but their roles remain the subject of much debate. We review the progress on the promotion nature of Fe, Mn, and Li. The roles of these promoters depend on the catalyst system and preparation procedures empolyed, which affect directly the interaction between Rh and promoter(s). This interaction determines the displayed structures and properties of the promoters, which behaves different effects on the elemental steps of CO hydrogenation reaction. This review is expected to deeply aid our understanding of the effects of these promoters.关键词
