Hydrothermal synthesis and catalytic properties of superacid sulfated titania
The micromorphology and catalytic properties of nanocrystalline TiO2/SO42− superacid systems prepared by a conventional sol-gel process, as well as hydrothermal (HT) and microwave-hydrothermal (MW-HT)
processes, were analyzed. The samples prepared by the HT process have no developed surfaces and, as a consequence, have no
high reactivity in isobutylene oligomerization. The TiO2/SO42− samples prepared by single-step MW-HT synthesis in their morphologic, acid, and catalytic properties are competitive with
the systems prepared by the conventional multistage sol-gel process.
