摘要

首次研究了磷对碳化钼反向水气变换(RWGS)反应催化性能的影响。研究发现,掺杂磷的碳化钼催化剂的催化活性和选择性在很窄的范围内(0-0.1)与磷/钼摩尔比有很大关系。很明显,增加 P/Mo 摩尔比会导致活性降低,但却能有效提高选择性。P/Mo 摩尔比为 0.05 的掺杂碳化钼被认为在活性和选择性方面都比其他掺杂 P 的碳化钼更优异,这归因于其较高的亲氧化性和对 CO 较弱的亲和性。

Novel phosphorus-doped molybdenum carbide catalyst for the reverse water-gas shift reaction

The effect of phosphorus on the catalytic performance of molybdenum carbide for the reverse water-gas shift (RWGS) reaction was studied for the first time. It was found that the catalytic activity and selectivity of the P-doped molybdenum carbide catalysts were greatly related to their P/Mo molar ratios within a narrow range (0–0.1). It was obvious that increasing P/Mo molar ratio led to a decreased activity, but can effectively enhance selectivity. The P-doped molybdenum carbide with a P/Mo molar ratio of 0.05 was proposed to be more excellent than other P-doped molybdenum carbides in terms of both activity and selectivity, which was attributed to its higher oxophilicity and weaker affinity toward CO.
