Our main areas of research are focusing on the synthesis of a wide range of functional materials (e.g., membranes, solid oxides, batteries, polymers, biomaterials, ceramics, transition-metal-complex compounds, etc.). We studied some of their applications as (not limited to) sustainable energy sources and alternative catalysts in homogeneous and heterogeneous processes. Our processes consider the principle of green chemistry which leads to a cleaner and more sustainable earth. More specifically, for example, we synthesize a wide range of metal oxide from nature which functions as photocatalysts for degrading toxic substances produced from industrial wastewater. We are also interested to develop biomass from rice husk which can be used as an alternative renewable energy source. We are also developing the first row of transition-metal complexes as catalysts (cheap, Earth-abundant, and less toxic) which designed as the alternatives to catalyze common organic synthetic widely used in industry (e.g., Suzuki-Miyaura cross-coupling, oxidative C–C cross-coupling, Miyaura borylation, etc.).
