Design of Shape‐Palladium Nanoparticles Anchored on Titanium(IV) Metal‐Organic Framework: Highly Active Catalysts for Reduction of p‐Nitrophenol in Water

Abstract The three‐dimensional microporous Ti‐based MOF material MIL‐125‐NH 2 (MIL: Material of Institut Lavoisier) was successfully used as a support for palladium nanoparticles designed as catalysts for p ‐nitrophenol hydrogenation. According to the mild and green synthetic approach, two catalysts of different nanoparticle morphology and different catalytic activity were obtained. Enhanced catalytic activity was found for a catalyst prepared using KBr as a capping agent, while Pd NPs of undefined shape synthesized without KBr were less active.
