摘要

g-C3N4 coupled with high specific area TiO2(HSA-TiO2) compos-ite was prepared by a simple solvothermal method,which was easy to operate with low energy consump-tion.Degradation of methyl orange test results showed that HSA-TiO2 effectively improved the photocatalytic activity effectively.Photoelectrochemical 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.
