Bimetallic AgPd Nanoparticles Immobilized on Amine-Functionalized SBA-15as Efficient Catalysts for Hydrogen Generation from Formic Acid

HCOOH (FA) is considered as a potential hydrogen-storage material. The chemically stored hydrogen in FA can be catalyti-cally released even at room temperature, which can be utilized by polymer electrolyte membrane fuel cells (PEMFCs). However, in order to make FA a feasible hydrogen-storage medium, it is necessary to find catalysts with superior performance that enable it to produce hydrogen under moderate conditions. Herein, for the first time to our knowledge, we report amine-functionalized SBA-15 (SBA-15-Amine)-supported bimetallic AgPd nanoparticles with various molar ratios through a facile co-reduction method for serve as a catalyst for the dehydro-genation reaction of FA. As indicated by the turnover frequency (TOF), the performance of these catalysts depended on their composition. Among all the prepared AgPd/SBA-15-Amine catalysts, Ag1Pd9/SBA-15-Amine exhibited exceedingly high activity for the dehydrogenation of FA to yield high-quality H-2 at 323 K, with a maximum TOF of 964 h (-1) and 100% selectivity. It is revealed that the catalyst exhibits stable catalytic performance after multiple usage cycles. Therefore, the catalyst we developed can be a potential candidate for prompting the widespread utilization of FA as a hydrogen-storage material.
