Abstract
Three hyperbranched polyglycerols with different molecular weight were synthesized by controlling the molar ratio of monomer and initiator. La-doped TiO2 catalysts were synthesized by those HPG as a templating agent for size control of La/TiO2. The photocatalytic elimination of methanol was used as model reactions to evaluate the photocatalytic activity of the catalysts. The size of La/TiO2 particles could be adjusted by changing the molecular weight of the HPG. With the molecular weight of HPG increase, the size of La/TiO2 particles decrease, the photocatalytic activity of the as-prepared catalysts enhance. This catalytic reaction follows the Langmuir-Hinshellwood mechanism.
