These radicals are utilized to break down MB by transforming it into low-molecular-weight intermediates, which are then changed into H2O, CO2, and inorganic ions via an oxidative mechanism [50]. Figure 8. Schematic representation of the MB sunlight catalytic degradation mechanism over the BZFG ...
{001} facets and the possible formation mechanism of microspheres was proposed, meanwhile a new idea for controllable preparation of TiO2hierarchical microspheres was also provided. The as-obtained TiO2microspheres exhibited high photocatalytic activity on degradation of TC solution under xenon lamp ...

MH2O]. The method of photocatalytically degrading the methyl orange-methylene blue mixture dye by using the zinc-tin binary hydrotalcite has the advantages of mild reaction conditions, high degradation efficiency and obvious effect, and the catalytic degradation product can be easily recycled.倪哲明...
About 95% degradation of dye was observed on the addition of 2 g/L ZnS in 50 mg/L dye solution after 90 minutes illumination at 125 W. Degradation has been increased up to 99% using UV/nanoparticles/H2O2 (50 mL/L) combined process. The degradation efficiency was also compared using Mn...
