Abstract:

Transition metal carbides (TMCs) are formed by carburizing reaction of parent metal compounds. They have variable structure and noble metal like electronic properties. They are a kind of inexpensive but important materials in heterogeneous catalysis, providing great potential for large-scale industrial applications. Integrating carbon atoms into the parent metals leads to the expansion of metal lattice and structural rearrangement, which then broadens the metal d band with a greater density of state and alters the electronic properties. They are used in catalytic hydrogenation, hydrodeoxygenation(HDO) and hydrogenolysis and other important catalytic reactions showed excellent performance. In recent years, significant progress has been achieved in developing efficient and highly-stable TMCs in catalytic reactions. However, it remains great challenging to investigate the surface properties and understand the structure-activity relationship in these materials due to their inherent complexity of carbides involving phase purity, surface defects, surface termination and surface oxides. In this review, we firstly give a brief introduction on the current status and then summarize the recent progress in the development of TMCs towards HDO of representative oxygenates in pyrolysis bio-oil. Based on the analysis of the reaction pathway of representative oxygenates in pyrolysis bio-oil, the design and preparation strategy of TMCs, and the relationship between their structure and HDO catalytic performance are emphatically discussed. Finally, the R&D direction and prospect of TMCs as catalytic materials for HDO of biomass-derived oxygenates are proposed.

摘要:

过渡金属碳化物由母体金属化合物经渗碳反应而形成,具有多变的结构组成和类贵金属的电子性质,是一类具有广泛应用前景的廉价催化材料,在催化加氢、加氢脱氧(hydrodeoxygenation,简写为HDO)和氢解等诸多重要催化反应中表现出优异的性能。近年来,对过渡金属碳化物的研究及其催化应用取得显著进展,但由于其固有的复杂性如相组成、表面缺陷与物种等导致构效关联等科学问题尚不清晰,仍有待进一步研究。本文综述了近年来过渡金属碳化物在生物质热解油中代表性含氧化合物HDO制备燃料和高附加值化学品中的研究进展,在分析了代表性含氧化合物反应路径的基础上,重点介绍了过渡金属碳化物的设计与合成策略及其结构与HDO催化性能关联,并展望了过渡金属碳化物作为生物质基含氧化合物HDO催化材料的研发方向与发展前景。
