摘要

由于其优异的性能,难熔性氮化钼(monx)基化合物具有广泛的战略性工业应用。本文综述了使MoN x材料成为许多化学反应的有效催化表面的电子和结构特性,并综述了其合成、工艺和在石油工业等相关工业中的催化应用。特别是,加氢、加氢脱硫和加氢脱氧是石油精炼及其转化为商品燃料和平台化学品的基本过程。催化剂表面的n空位是多种化学现象的重要驱动因素。对各种反应途径的研究都强调,从n空位上吸附氢原子的转移降低了关键结构键断键的激活障碍。密度泛函理论最近提供了一个原子水平的理解Mo-N系统的有效成分在加氢处理过程。这些Mo-N系统有可能扩展到更复杂分子的氢化,最值得注意的是,含氧芳香族化合物。

Molybdenum nitrides from structures to industrial applications
Abstract Owing to their remarkable characteristics, refractory molybdenum nitride (MoN x )-based compounds have been deployed in a wide range of strategic industrial applications. This review reports the electronic and structural properties that render MoN x materials as potent catalytic surfaces for numerous chemical reactions and surveys the syntheses, procedures, and catalytic applications in pertinent industries such as the petroleum industry. In particular, hydrogenation, hydrodesulfurization, and hydrodeoxygenation are essential processes in the refinement of oil segments and their conversions into commodity fuels and platform chemicals. N-vacant sites over a catalyst’s surface are a significant driver of diverse chemical phenomena. Studies on various reaction routes have emphasized that the transfer of adsorbed hydrogen atoms from the N-vacant sites reduces the activation barriers for bond breaking at key structural linkages. Density functional theory has recently provided an atomic-level understanding of Mo–N systems as active ingredients in hydrotreating processes. These Mo–N systems are potentially extendible to the hydrogenation of more complex molecules, most notably, oxygenated aromatic compounds.
