Well-dispersed Rh(OH) 3 nanoparticles were deposited in the interlayer galleries of a Dion-Jacobson type layered perovskite (ACa 2Nb 3O 10: A = H or K). X-ray photoelectron spectra and ζ potential measurements suggest covalent bonding (Rh-O-Nb) between the nanoparticles and the niobate sheets. After calcination of Rh(OH) 3/KCa 2Nb 3O 10 at 350°C in air, interlayer Rh(OH) 3 nanoparticles were transformed to Rh 2O 3 and showed higher photocatalytic activity for hydrogen evolution using methanol as a sacrificial electron donor.
