| dcterms.abstract | Polyaniline (PANI), one of the most important conducting polymers, has been studied intensely in recent years for its unique properties. Tungsten trioxide (WO3), on the other hand, is an important functional semiconductor. In this work, a hybrid mat based on PANI and WO3 was synthesized via spin coating and tested as a visible light photocatalyst. A PANI/TiO2 composite photocatalyst was made in the same way and its photocatalytic response was compared to that of PANI/WO3 and of pure WO3, respectively, under visible light for the remediation of methylene blue in water. Furthermore, the effect of salinity on the spontaneous photolysis of Methylene blue in the absence of a catalyst has been studied. From the spectroscopic study results of WO3/PANI mat, TiO2/PANI mat and pure WO3, the hybrid WO3/PANI mat shows a very good degradation rate of Methylene blue solution, which is almost 88%, compare to around 39% degradation rate of TiO2/PANI and 62% of pure WO3 (same weight of the WO3 percent in WO3/PANI), the result show a very effective improvement of photocatalytic activity of WO3 by modification with PANI. Besides, the spectroscopic results of spontaneous photolysis of methylene blue also show that the salinity of the content of NaCl has a slightly inhibiting influence on methylene blue degradation. | |
