Abstract:
The novel AgCl/Ag 2 SO 3 hybrids as an efficient photocatalyst had been fabricated by an in situ synthetic method. The correlations between the structure and the photocatalytic properties of the as‐fabricated hybrids were analyzed. Experimental results exhibited that with increasing the amount of Ag 2 SO 3 , the degradation rate of the as‐obtained samples was firstly increased and then decreased under the visible light irradiation. When the mass ratio of AgCl to Ag 2 SO 3 was 1:2, in 30 min, it displayed the highest degradation rate of 99.2% for rhodamine‐B, which was obviously higher than 46.1, 60.5, and 14.6% of pure AgCl, Ag 2 SO 3 , and TiO 2 (P25), respectively. Similar results could be found in degradation of methyl orange. It had the maximum of 97.4% in 90 min, which was higher than 55.2, 48.7, and 12.7% of pure AgCl, Ag 2 SO 3 , and P25, respectively. Moreover, the as‐prepared hybrids possessed the enhanced separation and transfer of photo‐generated electron–hole pairs compared to the pure samples. In addition, the holes and superoxide radicals played the dominant role and the hydroxyl radicals played the secondary role during the process of photocatalytic degradation.
