Đặng TNH, Nguyễn Nguyen Đức H. Synthesis of soluble titanium peroxide complex and catalytic performance with TiO2/g-C3N4 system. hueuni-jns [Internet]. 2022Mar.31 [cited 2023Sep.29];131(1A):35-42. Available from:


This paper presents the synthesis of the titanium peroxide complex and the photocatalytic activity of the TiO2/g-C3N4 system. The prepared materials were characterized by using UV-Visible Diffuse Reflectance Spectroscopy, X-ray diffraction, scanning electron microscopy, transmission electron microscopy, and Fourier-transform infrared spectroscopy. The titanium peroxide complex with high TiO2 content and the TiO2/g-C3N4 system of 1:1 (w/w) has good catalytic activity. This material can be used in polluted-wastewater treatment.
