Abstract

The molybdate-incorporated hydrotalcite-type α-Ni(OH)₂ catalysts were prepared by the post-synthesis method. The synthesized catalyst was thoroughly studied using several physicochemical characterization methods. The catalytic activity of the material was studied on biomass model compounds such as anisole hydrotreating and the oxidation of iso-eugenol. The catalyst shows a significant conversion for the anisole hydrotreating in vapour phase conditions, yielding a steady-state conversion of 30% even after 10 h of time-on-stream (TOS). The primary product was benzene, with other products, viz., methyl anisole, methylcyclohexane, and toluene, as minor components. The catalyst also has the potential for iso-eugenol oxidation and shows 76.1% conversion with 75.5% selectivity for vanillin at 100 °C, 5 h.

Graphical abstract

Molybdate-incorporated hydrotalcite-type α-Ni(OH)₂ catalysts have the potential for oxidation of iso-eugenol to vanillin in the presence of an oxidant in a liquid phase and hydro-deoxygenation in the vapour phase under a hydrogen atmosphere.

钼酸盐掺入α-Ni(OH)2:异丁香酚氧化和苯甲醚加氢处理的潜在催化剂

采用后处理法制备了钼酸盐掺杂的水滑石型α-Ni(OH)2催化剂。采用多种物理化学表征方法对合成的催化剂进行了深入的研究。研究了该材料对苯甲醚加氢处理和异丁香酚氧化等生物质模型化合物的催化活性。该催化剂在气相条件下对苯甲醚加氢处理有显著的转化率，即使在10小时的流上时间(TOS)后也能产生30%的稳态转化率。主要产品是苯，其他产品，即甲基苯甲醚、甲基环己烷和甲苯，作为次要成分。该催化剂对异丁香酚也有氧化的潜力，在100℃，5 h的条件下，对香兰素的转化率为76.1%，选择性为75.5%。图摘要:钼酸盐掺入型α-Ni(OH)2催化剂在液相中有氧化剂存在时可将异丁香酚氧化为香兰素，在氢气氛下可在气相中加氢脱氧。

期刊介绍： Journal of Chemical Sciences is a monthly journal published by the Indian Academy of Sciences. It formed part of the original Proceedings of the Indian Academy of Sciences – Part A, started by the Nobel Laureate Prof C V Raman in 1934, that was split in 1978 into three separate journals. It was renamed as Journal of Chemical Sciences in 2004. The journal publishes original research articles and rapid communications, covering all areas of chemical sciences. A significant feature of the journal is its special issues, brought out from time to time, devoted to conference symposia/proceedings in frontier areas of the subject, held not only in India but also in other countries.
