主　　题：Core-shell Fe_(3)O_(4) Catalysis Dehydrogenation Formic acid 

摘      要：Currently,one of the critical issues in the world is finding an appropriate green alternative to fossil fuels due to the concerns about global *** a hydrogen source,formic acid has been given particular attention owing to the attractive features such as highenergy density,no toxicity,high stability at ambient temperature and high hydrogen *** an affordable and highly efficient catalyst with easy recovery from the reaction mixture for selective dehydrogenation of formic acid is still *** this report,we used a simple onestep process to synthesize Ni@Pd core shell nanoparticles on 3aminopropyltriethoxysilane modified Fe3O4 *** existence of Ni and Pd results in a synergic effect on the catalytic ***—NH2 groups play an important role for obtaining welldispersed ultrafine particles with high surface area and active *** addition,Fe3O4 lead to convenient magnetic recovery of the catalyst from reaction *** results indicate that the asprepared catalyst give the superb turnover frequency of 5367.8 h 1 with no additive,which is higher than most of the previously reported catalysts.
