Project title: Development of Semiconductor-based Heterojunction Photoelectrodes and Integrated System for Sustainable Hydrogen Fuel Production
Dwindling of carbon-based energy sources has prompted for the research and development (R&D) needs of alternative and renewable energy sources. Hydrogen as a fuel, is widely regarded as a renewable and sustainable energy source owing to its high abundance and non-polluting nature in the environment. In order to produce hydrogen fuel, however, a secondary energy source is required to convert the source of hydrogen (water) to energy carrier (H2 gas). In this instance, the conventional thermo-catalytic approach is usually regarded as economically infeasible as it requires vast energy from other expensive energy sources for hydrogen fuel production, as well as the emission of environmental deleterious greenhouse gases (GHG). In this proposed project, novel semiconductor-based heterojunction photoelectrodes will be fabricated and further integrated in a photoelectrochemical (PEC) system (together with my co-applicant, Dr Junwang Tang at UCL) to harness the potential benefits and abundance of solar irradiation in Malaysia and UK for hydrogen fuel production from water splitting reaction. Through this research project, it is expected that a greater insight into the roles of metals/non-metals nanostructured materials and their combinations could be attained and influence of weather conditions between the two countries on solar H2 production by PEC water splitting would be achieved. It is anticipated that the solar hydrogen produced could provide a cost-effective solution to close the renewable energy loop in both Malaysia and UK.
