Abstract
Abstract TiO 2 with a disc‐like morphology was prepared by direct pyrolysis of a titanium metal–organic framework [MIL‐125(Ti)] in air. Highly dispersed bimetallic AgPd nanoparticles were then anchored on TiO 2 and their catalytic performance in the dehydrogenation of formic acid was systematically investigated. The Ag/Pd ratio had a significant effect on the catalyst activity, with Ag 2 Pd 8 /TiO 2 exhibiting the highest total turnover frequency value of 2579 h −1 at 60 °C under an ambient atmosphere. This excellent performance was attributed to the low‐crystallinity anatase phase structure and large specific surface area of the TiO 2 carrier, the alloying effect of the AgPd nanoparticles, and abundant electron transfer between the carrier and metal alloy nanoparticles.
