The Role of Zirconia Surface on Catalytic Activity of Tungstated Zirconia via Two-Phase Esterification of Acetic Acid and 1-Heptanol

摘要

It is proven that surface nature of zirconia can play crucial roles on determining the catalytic activity of tungstated zirconia catalysts. The solvothermal method for preparation of crystalline zirconia support can result in the formation of Zr-OH bond on its surface. This surface species related to the Zr-heteropolyacid, acting as strong Br0nsted acid sites. It consequently affected on the catalytic activity.
