A bisacylphosphine oxide photoinitiator was used for a very convenient light mediated preparation of palladium nanoparticles (PdNPs) with a small diameter of 2.8 nm. The PdNP-hybrid material was applied as catalyst for the semihydrogenation of various internal alkynes to provide the corresponding alkenes in excellent yields and Z-selectivities.
