AI Article Synopsis
- A novel hybrid photocatalyst called B-TiO-Ru(ii) was created by combining a B derivative with ruthenium and attaching it to TiO microspheres, which were fully characterized through several techniques like DRS and SEM.
- The hybrid photocatalyst was able to completely dechlorinate DDT and produced some tridechlorinated products after just 30 minutes of visible light exposure.
- It also showed improved photocatalytic activity under simulated sunlight compared to other conditions and can be reused efficiently, marking it as the first B-based photocatalyst that uses two photosensitizers for a broader spectral response.
Article Abstract
A novel hybrid photocatalyst denoted as B-TiO-Ru(ii) was prepared by co-immobilizing a B derivative and trisbipyridine ruthenium (Ru(bpy) ) on the surface of a mesoporous anatase TiO microspheres and was characterized by DRS, XRD, SEM and BET By using the hybrid photocatalyst, DDT was completely didechlorinated and a small part of tridechlorinated product was also detected in the presence of TEOA only after 30 min of visible light irradiation. Under simulated sunlight, the hybrid exhibited a significantly enhanced photocatalytic activity for dechlorination compared with B-TiO under the same condition or itself under visible light irradiation due to the additivity in the contribution of UV and visible part of the sunlight to the electron transfer. In addition, this hybrid catalyst can be easily reused without loss of catalytic efficiency. This is the first report on a B-based photocatalyst co-sensitized by two photosensitizers with wide spectral response.
