  • G-C3N4 coupled with high specific area TiO2 (HSA-TiO2) composite was prepared by a simple solvothermal method, which was easy to operate with low energy consumption. Degradation of methyl orange test results showed that HSA-TiO2 effectively improved the photocatalytic activity effectively. PEC test results indicated that the separation of photo-generated carriers and the charge carrier migration speed of TiO2 were improved after combination with g-C3N4. G-C3N4/ HSA-TiO2 showed strong photocatalytic ability. The degree of degradation of methyl orange by 6%-g-C3N4/ HSA-TiO2 could reach up to 92.44%. Furthermore, it revealed good cycle performance. The photocatalytic mechanism of g-C3N4/ HSA-TiO2 was proposed.

Photocatalytic performance and mechanism study of high specific area TiO2 combined with g-C3N4

Abstract: G-C3N4 coupled with high specific area TiO2 (HSA-TiO2) composite was prepared by a simple solvothermal method, which was easy to operate with low energy consumption. Degradation of methyl orange test results showed that HSA-TiO2 effectively improved the photocatalytic activity effectively. PEC test results indicated that the separation of photo-generated carriers and the charge carrier migration speed of TiO2 were improved after combination with g-C3N4. G-C3N4/ HSA-TiO2 showed strong photocatalytic ability. The degree of degradation of methyl orange by 6%-g-C3N4/ HSA-TiO2 could reach up to 92.44%. Furthermore, it revealed good cycle performance. The photocatalytic mechanism of g-C3N4/ HSA-TiO2 was proposed.
