Low-temperature ortho para hydrogen conversion catalyzed by gold nanoparticles: Particle size does not affect the rate

Catalytic activity of 4-40 nm gold nanoparticles supported on gamma-Al2O3 in the reaction of ortho para conversion of protium has been studied. The results of test indicate that nanoparticles exhibit a high catalytic activity and the rate of reaction, virtually does not depend on the particle size. (C) 2017 Hydrogen Energy Publications LLC.
