|Title:||Synthesis of metal halide perovskites for photoredox catalysis, photoelectgric devices, and solid-state characterization of main group materials||Authors:||Hong, Zonghan||Keywords:||DRNTU::Science::Chemistry::Physical chemistry::Catalysis||Issue Date:||2019||Source:||Hong, Z. (2019). Synthesis of metal halide perovskites for photoredox catalysis, photoelectgric devices, and solid-state characterization of main group materials. Doctoral thesis, Nanyang Technological University, Singapore.||Abstract:||Extensive research has been carried out to address the rising concerns of high energy consuming industry and environmental problems. In this thesis, three main projects have been developed and thoroughly investigated, dedicated to addressing some of these problems. The first two chapters focus on the syntheses and applications of metal halide perovskites while the third chapter reveals a different perspective of main group chemistry regarding NaH-NaI composite that promotes dehalogenation and decyanation to mitigate the environmental impact of harmful organic compounds. As earth-abundant materials, metal halide perovskites have been attracting broad research interest as photosensitizers with promising photoelectric and photophysical properties but their application in photocatalysis is severely under-explored. Meanwhile, the scalability and reproducibility of the synthesis are still below satisfactory. Targeting these issues, energy efficient syntheses of metal halide perovskites were developed up to kg-scale, and the products were successfully employed in artificial photosynthesis and the fabrication of photoelectrical devices. Additionally, a characterization study of simple NaH-NaI composite that performs dehalogenation and decyanation was conducted, revealing a thorough understanding of the unique reactivity and an alternative approach to reduce the adverse environmental impacts caused by hazardous industry chemicals.||URI:||https://hdl.handle.net/10356/89073
