Sun Y, Zhang W, Ma TY, Zhang Y, Shimakoshi H, Hisaeda Y, Song XM. Enhanced photocatalytic activity of a B 12-based catalyst co-photosensitized by TiO 2 and Ru(ii) towards dechlorination. RSC Adv 2018; 8:662-670. [PMID: 35538989 PMCID: PMC9076874 DOI: 10.1039/c7ra13037f] [Citation(s) in RCA: 4] [Impact Index Per Article: 0.7] [Reference Citation Analysis] [Abstract] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 12/04/2017] [Accepted: 12/18/2017] [Indexed: 11/21/2022] Open
Abstract
A novel hybrid photocatalyst denoted as B12-TiO2-Ru(ii) was prepared by co-immobilizing a B12 derivative and trisbipyridine ruthenium (Ru(bpy)3 2+) on the surface of a mesoporous anatase TiO2 microspheres and was characterized by DRS, XRD, SEM and BET et al. 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 B12-TiO2 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 B12-based photocatalyst co-sensitized by two photosensitizers with wide spectral response.

Abstract
We report a promising photoanode material of Fe2O3/BiOI for efficient photoelectric conversion in solar cells, which was fabricated with BiOI attached to a one-dimensional Fe2O3 nanorod array. The two semiconductors of p-type BiOI and n-type Fe2O3 formed a heterogeneous structure for efficient charge separation. The highest open circuit voltage and short circuit current of the solar cell can reach 0.41 V and 4.89 mA/cm2, respectively. This study opens an available field to develop low-cost and environmentally friendly photoelectric materials for solar cells.

Abstract
We reported a novel BiOI/mesoporous TiO2 photoanode for solar cells, which was fabricated with BiOI attached onto a three-dimensional mesoporous TiO2 film by a chemical bath deposition (CBD) method. BiOI was revealed as an efficient and environmental friendly semiconductor sensitizer to make TiO2 respond to visible light. Based on this photoanode, mesoporous TiO2-based solar cell sensitized by BiOI exhibited promising photovoltaic performance. Meanwhile, the optimization of photovoltaic performance was also achieved by varying cycles of deposition immersions. The highest open circuit voltage and short circuit current of the solar cell can reach 0.5 V and 1.5 mA/cm(2), respectively.
