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.
期刊介绍:
Accounts of Chemical Research presents short, concise and critical articles offering easy-to-read overviews of basic research and applications in all areas of chemistry and biochemistry. These short reviews focus on research from the author’s own laboratory and are designed to teach the reader about a research project. In addition, Accounts of Chemical Research publishes commentaries that give an informed opinion on a current research problem. Special Issues online are devoted to a single topic of unusual activity and significance.
Accounts of Chemical Research replaces the traditional article abstract with an article "Conspectus." These entries synopsize the research affording the reader a closer look at the content and significance of an article. Through this provision of a more detailed description of the article contents, the Conspectus enhances the article's discoverability by search engines and the exposure for the research.
