摘要: Abstract In this paper, amorphous Ti-peroxo complexes (ATPC) were successfully synthesized by a facile exothermic sol-gel method without annealing process. The TiH2 and H2O2 are used as starting precursor oxidative polymerization agent. color of prepared ATPC powder was changed from green to yellow with increase which directly induce the formation small flakes on ATPC, resulted in high surface area (154.1 m2/g). Raman FT-IR spectra shows that more peroxo groups such Ti–OOH, Ti–O–O–Ti -O-Ti-O- colored formed than ATPC. These not only accelerate photocatalytic activity abundant superoxide anion radicals, but also oxygen vacancies can lead visible-light activity. remarkable induced 95% decolorization Rhodamine B within 30 min. Compare previous researches related titania based photocatalyst, excellent recycling property maintained rate.
