Abstract

Well-dispersed Rh(OH)3 nanoparticles were deposited in the interlayer galleries of a Dion-Jacobson type layered perovskite (ACa2Nb3O10: A=H or K). X-ray photoelectron spectra and zeta potential measurements suggest covalent bonding (Rh-O-Nb) between the nanoparticles and the niobate sheets. After calcination of Rh(OH)3/KCa2Nb3O10 at 350 degrees C in air, interlayer Rh(OH)3 nanoparticles were transformed to Rh2O3 and showed higher photocatalytic activity for hydrogen evolution using methanol as a sacrificial electron donor.
