采用溶胶-凝胶法制备了InOx/TUD-1，并对其进行了表征。根据不同的表征结果，发现海绵状多孔InOx/TUD-1（In/Si = 8/100）基质中含有小的+ 3氧化态氧化铟微晶。InOx/TUD-1（In/Si = 8/100）催化剂对以分子氧和牺牲试剂苯甲醛为原料的环酮Baeyer-Villiger氧化反应具有良好的催化效果。在分子氧存在下，使用极性非质子溶剂例如二氯乙烷、乙腈和苯甲腈，发现环己酮转化率为100%，ε-己内酯选择性为100%。
InOx/TUD-1 is prepared by sol–gel method and characterized by different techniques. On the basis of different characterization results it is found that spongy porous InOx/TUD-1 (In/Si = 8/100) matrix contains small crystallite of indium oxide in + 3 oxidation state. InOx/TUD-1 (In/Si = 8/100) catalyst shows good catalytic results for Baeyer–Villiger oxidation of cyclic ketones using molecular oxygen and sacrificial reagent benzaldehyde. The cyclohexanone conversion was found 100% withε-caprolactone selectivity 100% using polar aprotic solvents e.g. dichloroethane, acetonitrile and benzonitrile in the presence of molecular oxygen.
