| Abstract | Hydrogenation has been demonstrated in successfully modifying the structural, electronic and optical properties of TiO2 nanoparticles, along with its improved photocatalytic performance. In our original study, hydrogenated black TiO2 nanoparticles were obtained by heating white crystalline TiO2 nanocrystals in a high-pressure pure hydrogen environment. This treatment induced a thin disordered layer near the surface, surrounding a crystalline core. This layer was believed to introduce extra electronic states in the bandgap and the longwave length absorption. The hydrogenated black TiO2 nanoparticles showed excellent and stable photocatalytic performance in photocatalytic hydrogen generation and pollutant (methylene blue and phenol) decomposition. The enhancement was partially attributed to the efficient electron and hole trapping in the disordered layer to allow better charge separation on the surface. Hydrogenated black TiO2 nanoparticles have also been developed with other fabrication approaches as well, such as electrochemical hydrogenation and hydrogen plasma. So far, hydrogenated TiO2 nanocrystals have |
