摘要

本文利用原位液体核磁共振技术对真实固液体系光催化甲醇重整过程中水与甲醇之间的相互作用进行了系统性研究,证实了甲醇+水体系中氢键及质子交换相互作用的存在,并且发现催化剂的种类(包括不同晶型,以及同一晶型、不同形貌的TiO2)、体系温度、光照反应条件都会影响甲醇与水之间的相互作用,进而影响到甲醇重整的效率.这表明催化剂及温度的合适选择对于提升甲醇重整效率起到非常重要的作用.

Abstract

In this work, an operando NMR method was used to investigate the interaction between water and methanol in photocatalytic methanol reforming process in a real solid-liquid environment. The existence of hydrogen bonding and proton exchange between water and methanol were proven. The experimental results demonstrated that, the interaction between methanol and water is affected by the type of catalyst, reaction temperature and light irradiation, which consequently influences the methanol reforming efficiency. It was also shown that selection of the appropriate temperature and catalyst could improve methanol reforming efficiency.
