W、N和C共掺杂TiO2催化剂的制备及其光解水析氢性能
Preparation of W/N/C-Tridoped TiO2 Photocatalyst with Excellent Photocatalytic H2Evolution Performance
摘要
Abstract
Nitrogen/carbon/tungsten-tridoped TiO2 photocatalyst was synthesized by a wet chemical method. The experiment results reveal that tungsten exists in the oxidation state of +6 and incorporates into the lattice of TiO2 by substituting Ti atoms. Nitrogen and carbon are incorporated into the lattice of TiO2 in interstitial mode. The light absorbance in UV-visible region is improved by tridoping with nitrogen, carbon and tungsten, leading to a narrower band gap (about 3.0 eV) and a better photocatalytic H2 evolution performance rather than those of pure and nitrogen/ carbon-codoped TiO2. The excellent photocatalytic H2 evolution performance of nitrogen/carbon/tungsten-tridoped TiO2 photocatalyst is attributed to the narrow band gap, the intense UV light absorption and the proper electronic structure.关键词
