Phosphane‐decorated Platinum Nanoparticles as Efficient Catalysts for H2 Generation from Ammonia Borane and Methanol

A series of narrowly dispersed Pt nanoparticles of 1.5–2.2 nm in size stabilized by bulky terphenylphosphane ligands has been synthesized by the organometallic method using [Pt(dba)2] as platinum source. These nanoparticles are highly efficient catalysts for hydrogen generation by methanolysis of am...
