| 摘要 | Highly homogeneous TiO2@phenolic resol hybrid nanocomposites are fabricated by a solvothermal method. In such nanostructures, the TiO2 particles are tightly grafted on the surface of nano mesoporous phenolic resols to form uniform heterostructures. Significantly, a charge transfer complex was formed at the interface of the TiO2 and the nano mesoporous phenolic resols, which led to visiblelight absorption over the full range. The nano hybrid material exhibited excellent performance for the photocatalytic degradation of dyes and produced photocurrent signals under visible-light. The investigation of the mechanism indicated that the O2_ was the main active species during the photochemical process. The hybrid nanocomposites also showed considerably high stability in the photocatalysis. It is expected that this approach can provide a new strategy for the design of some bio-inspired catalysts for sustainable technology. ; Highly homogeneous TiO2@phenolic resol hybrid nanocomposites are fabricated by a solvothermal method.
