Photocatalytic hydrogen production from water-methanol mixtures over Pt/Ru2O/ PbBi2Nb2O9 under visible light irradiation (λ＞420 nm) |
| 초록 |
Perovskite-type oxide materials based on transition metals with d(0) electron configuration such as NbV, TaV, and TiIV are efficient photocatalysts for overall water splitting with high quantum yields. Very recently, we have succeeded in fabricating an undoped, a single-phase oxide photocatalyst, PbBi2Nb2O9, an Aurivillius-phase perovskite, which is an efficient photocatalyst for decomposition of water into O2 or H2 under visible light irradiation. We also have succeeded in fabricating a novel configuration of composite solids designated as photocatalytic nanodiodes (PCD) formed by p- and n-type semiconductors. Here we report Photocatalytic hydrogen production from water-methanol mixtures over Pt/Ru2O/PbBi2Nb2O9 under visible light irradiation (λ＞420 nm). |
