In BZY_(10), addition of ZnO leads to a monotonically decreased DC electrical conductivity. In SZY_(10), addition of 2~5 mol% ZnO had benecial effects on its protonic conduction.

ZnO主要以固溶取代的形式存在于SZY_(10)和BZY_(10)晶格中，其在晶格中固溶使晶格缺陷增加是主要的促烧机理。

Titanium incorporated mesoporous molecular sieves Ti-MCM-41, Ti-HMS, and Ti-MSU were synthesized through S〓I〓, S〓I〓, and N〓I〓 pathways using cetylpyridium bromide, tetredecylamine, and polyoxyethylene (10) stearyl ether as the structure-directing agents, respectively. The framework structure and the titanium coordination environment of these materials were characterized by XRD, N〓 adsorption/desorption, TG, TEM, FT-1R, DR UV-Vis, and ICP-AES. It was confirmed that the titanium was highly dispersed in the silica-based framework positions, and all samples were free of extra framework titanium impurities. The catalytic performance of these titanium containing mesoporous materials was investigated in the oxidation of styrene with aqueous H〓O〓 as the oxidant.
