In the absence of an electron acceptor and the presence of a hole scavenger, the largest absorption change in the Rh valence state from tetravalent to trivalent was observed in Rh-doped SrTiO3 prepared at 1473 K, which showed the highest activity for hydrogen evolution. PA measurements revealed the effective redox cycle mechanism between tetravalent and trivalent Rh ions in Rh-doped SrTiO3.}, pages = {14255--14258}, title = {In situ photoacoustic analysis of near-infrared absorption of rhodium-doped strontium titanate photocatalyst powder}, volume = {56}, year = {2020}, yomi = {ムラカミ, ナオヤ} }
