Abstract

Supported metal hydrides are key reactive intermediates in various catalytic processes, such as hydrogenation and dehydrogenation, but are often challenging to characterize spectroscopically. Here, deuterium solid state nuclear magnetic resonance spectroscopy is used to understand the structure of the corresponding silica-supported zirconium hydrides after H/D exchange as an illustrative example of supported metal hydrides, which have been shown to display notable reactivity towards small molecules (e. g., CO₂ and N₂O) and to activate both C−H and C−C bonds, hence their use in to the conversion of hydrocarbons (alkanes, polyolefins etc.)

用氘四极性参数探讨表面氢化物的性质:以二氧化硅支撑的氢化锆为例

负载型金属氢化物是各种催化过程中的关键反应中间体，如加氢和脱氢，但通常具有挑战性的光谱表征。这里，氘固态核磁共振波谱被用来了解H/D交换后相应的二氧化硅负载的锆氢化物的结构，作为负载金属氢化物的一个例子，它已经被证明对小分子(例如CO2和N2O)表现出显著的反应性，并激活C-H和C-C键，因此它们用于碳氢化合物(烷烃，聚烯烃等)的转化。

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.
