The construction of TiO2 nanotube arrays with oxygen vacancies is widely used for the photoelectrocatalytic degradation organic pollutants, but crystal defects often reduce stability catalyst. This article mainly in preparation a supported porous catalyst by anodic oxidation Ti foil and loading Au nanoparticles assistance Cinnamomum camphora leaf extract. obtained Au/TiO2 array was applied to methyl orange. efficiency enhanced removal plant molecules calcination anaerobic conditions, reaction rate constant increased 66% when heat pretreated at 673 K. In addition, catalytic activity maintained high level after 5 cycles application. After characterization X-ray photoelectron spectroscopy, thermogravimetric analyses, Fourier transform infrared, electrochemical impedance photoluminescence, played important roles reduction gold ions, nucleation atoms, stabilization prevent collapse. method photoelectrocatalysts would be expected apply development catalysts toward pollutants.
