Synergistic catalysis of AgPd@ZIF-8 on dehydrogenation of formic acid

•Facile synthesis of highly dispersed AgPd immobilized by ZIF-8.•The catalysts exhibit 100% hydrogen selectivity toward dehydrogenation of FA.•The catalysts exhibit high catalytic activity with TOF value of 580 h−1 at 80 °C.

Highly dispersed bimetallic AgPd nanoparticles with different composition have been successfully deposited on the metal-organic frameworks (ZIF-8) by using a simple liquid impregnation method. The resultant catalysts are composition dependent toward dehydrogenation of formic acid, while Ag18Pd82@ZIF-8 exhibits exceedingly high catalytic activity, with the turnover frequency (TOF) value of 580 h−1, and 100% hydrogen selectivity at 80 °C.

Graphical abstractHighly dispersed bimetallic AgPd nanoparticles have been successfully deposited on the metal-organic frameworks (ZIF-8) by using a simple liquid impregnation method. The as-synthesized catalysts exhibit remarkable catalytic activity and 100% hydrogen selectivity toward dehydrogenation of formic acid at 80 °C.Figure optionsDownload full-size imageDownload as PowerPoint slide
