Research interest
Interested in using catalysis for environmental benefits and find a crossover between pollution remediation and sustainable energy production. CO2 hydrogenation is an example to utilise pollutant into a value added products. A major central point of my research is the synthesis and development of multifunctional catalyst that is based on synthesis of nanoparticles and development of solid acid catalysts. On a more fundamental level, I am also have a deep interest in using in-situ spectroscopy technique (EXAFS, XRD, FTIR) to understand interactions between metal nanoparticles and metal oxide support that can act as active sites that drive catalytic reactions.

Development of multifunctional catalysts
The development of multifunctional catalyst is based on controlling nanoparticles deposition to gain specific catalytic applications for more feasible correlation with catalytic evaluations. The synthesis is carried out based on colloidal deposition, chemical vapour impregnation, photochemical and electrochemical reductions. As for solid catalysts, material such as zeolites and mesoporous materials offer exciting opportunity to tune the acidity and to tailor surface functionality and pores design to accommodate desired catalytic reaction.

CO2 hydrogenation to fuels
Since the invention of first steam engine in 1698, the level of CO2 in the atmosphere has increased because of the consumption of carbon fossil as the source of energy, and this contributes into many environmental problem including global warming. CO2 utilisation covering every aspect of the conversion of CO2 to value added products particularly involving catalysts development. CO2 activation at mild reaction conditions requires bifunctional catalyst that allows hydrogenation of CO2 into methanol and subsequently convert methanol into higher hydrocarbons. Incorporating CO2 hydrogenation catalyst inside the cavity of solid acid support will generate close interaction that allow higher CO2 conversion

Photocatalytic water splitting
The project determined to develop a solar powered hydrogen generation from water splitting reaction with emphasis on generating novel materials and new understandings of photocatalytic materials and processes. TiO2 is still an ideal semiconductor, using a combination of nanotechnology to optimise the nanostructured and improving the efficiency with noble metal doping to enable potential solutions towards a working operations in the field


CO2 utilisation to value added products

This project aimed to utilize CO2 for production of value added products and as carbon feedstock for biofuels synthesis. The research will focus on key challenges in catalysts design and catalytic reaction. Student will be exposed to the synthesis of heterogeneous catalysts using impregnation method and deposition precipitation method. Catalytic reaction will be carried out using gas flow reactor at different temperature and pressure. Student also will have opportunities to collaborate with university in Malaysia, Indonesia and UK to carry out experiments and catalysts characterisation.
