Engineering of platinum–oxygen vacancy interfacial sites in confined catalysts for enhanced hydrogenation selectivity

A carbon-assisted thermal treatment strategy is introduced to create rich platinum–oxygen vacancy interfacial sites in TiO 2 nanotube confined Pt-based catalysts due to reducibility of carbon at high temperature. Compared with confined TiO 2 /Pt and unconfined Pt/TiO 2 -700-Ar, confined TiO 2 /Pt-70...

Summary:A carbon-assisted thermal treatment strategy is introduced to create rich platinum–oxygen vacancy interfacial sites in TiO 2 nanotube confined Pt-based catalysts due to reducibility of carbon at high temperature. Compared with confined TiO 2 /Pt and unconfined Pt/TiO 2 -700-Ar, confined TiO 2 /Pt-700-Ar presents greatly enhanced selectivity to p -aminobenzyl chloride in the hydrogenation of p -nitrobenzyl chloride.
