Abstract

A carbon-assisted thermal treatment strategy is introduced to create rich platinum–oxygen vacancy interfacial sites in TiO2 nanotube confined Pt-based catalysts due to reducibility of carbon at high temperature. Compared with confined TiO2/Pt and unconfined Pt/TiO2-700-Ar, confined TiO2/Pt-700-Ar presents greatly enhanced selectivity to p-aminobenzyl chloride in the hydrogenation of p-nitrobenzyl chloride.
