Abstract

This study focused on the development of vanadium-based catalysts for formic acid production from glucose. The influence of different vanadium precursors on the catalytic activity of titania supported catalysts was contemplated and compared to the performance of commercial and synthesized unsupported V2O5. The obtained results reveal a successful deposition of multiple vanadium species on TiO2 as confirmed by XRD, Raman, and UV-Vis measurements. Catalyst screening identifies V5+ species as main player indicating its important oxidizing potential. Afterwards, the key reaction conditions, as temperature, time, pressure and catalyst loading, were optimized as well as the state of the catalyst after the reaction characterized.

批式反应器中催化葡萄糖氧化为甲酸的 V2O5/TiO2 催化剂:钒物种性质与反应条件优化
本研究的重点是开发用于从葡萄糖中生产甲酸的钒基催化剂。研究考虑了不同钒前驱体对二氧化钛支撑催化剂催化活性的影响,并与商用和合成的无支撑 V2O5 的性能进行了比较。X射线衍射、拉曼和紫外可见光测量结果表明,多种钒物种成功沉积在二氧化钛上。催化剂筛选确定 V5+ 物种为主要成分,表明其具有重要的氧化潜力。随后,对温度、时间、压力和催化剂负载等关键反应条件进行了优化,并对反应后催化剂的状态进行了表征。

期刊介绍: Topics in Catalysis publishes topical collections in all fields of catalysis which are composed only of invited articles from leading authors. The journal documents today’s emerging and critical trends in all branches of catalysis. Each themed issue is organized by renowned Guest Editors in collaboration with the Editors-in-Chief. Proposals for new topics are welcome and should be submitted directly to the Editors-in-Chief. The publication of individual uninvited original research articles can be sent to our sister journal Catalysis Letters. This journal aims for rapid publication of high-impact original research articles in all fields of both applied and theoretical catalysis, including heterogeneous, homogeneous and biocatalysis.
