Abstract
Pt nanoparticles were synthesized by a cavitation bubble plasma (CBP) with a pair of Pt rod electrodes. Pt nanoparticles were loaded on TiO2 particles to produce Pt/TiO2 photocatalysts. Regardless of the processing time during nanoparticle synthesis, the Pt nanoparticles were spherical shape of diameter about 1.5 to 3.0 nm. Pt nanoparticles supported on TiO2 particles increased in particle size due to agglomeration with increasing processing time. The hydrogen production amount by the photocatalytic reaction of Pt/TiO2 in glycerol solution increased with increasing CBP processing time, reaching 71.1 μmol/h at 5 minutes of processing time.
