Hybrid nanomaterials for photoanodes in photoelectrochemical water splitting

The urgent need for clean and renewable energy sources has prompted intense research in the field of solar-driven water splitting, with a specific focus on photoanode materials. In this context, this doctoral dissertation investigated the development of photoanode materials to advance the efficiency of photoelectrochemical water splitting, emphasizing the paramount importance of modifying charge dynamics and enhancing light harvesting capacity. Multifunctional ZnO in various nanoforms was chosen as the primary light absorber in the multi-component nanocomposite systems that were actualized by three well-established strategies. These strategies include surface modification, simultaneous effects of conductive metal coating and gradient impurity element doping, and photosensitization by a narrow band gap semiconductor. The adopted methodologies provided a visible light activity to ZnO-based photoanodes and unveiled several vital factors influencing photoelectrochemical performance. Employing cutting-edge spectroscopic and microscopic techniques, morphological, crystallographic, optical, and electrical properties and their significance on photoelectrochemical water splitting were comprehensively analyzed. The outcomes of this research deepen our understanding of photoanode materials and offer practical insights for developing highly efficient and stable photoelectrodes. This dissertation will hopefully serve as a valuable contribution to the field, addressing the challenges associated with harnessing solar energy for clean and renewable energy production.
