NH₂-MIL-125(Ti) modified graphitic carbon nitride with carbon vacancy for efficient photocatalytic NO removal

This paper reports the application of NH₂-MIL-125(Ti) modified carbon nitride C_v-C₃N₄ with carbon vacancies in the removal of NO. We performed a series of characterizations of the complex and compared various ratios with the individual components. The results of UV spectrum analysis show that the composite's range of light absorption expanded due to the modification of Ti metal-organic framework. Furthermore, the results of photocurrent and electrical impedance indicate the compound has a better ability to generate and transfer electrons. The increase in the compound's NO removal efficiency (up to 63%) indicates that MOF has a positive effect on C_v-C₃N₄ modification-a good method for photocatalysis. Moreover, the compound can promote photocatalysis in a favorable direction.
