title = "In situ photoacoustic analysis of near-infrared absorption of rhodium-doped strontium titanate photocatalyst powder",
abstract = "Near-infrared absorption of strontium titanate (SrTiO3) doped with rhodium (Rh) was investigated by photoacoustic (PA) Fourier transform infrared spectroscopy. 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.",
