REL is a fusion research laboratory in designing and fabricating nano energy material for hydrogen production and biomass conversion. In our research, we develop multi-functional nanomaterial for oxygen reduction reaction, and oxygen evolution reaction in renewable energy system. We are looking for novel and efficient way to fabricate heterogeneous catalysts for conversion of biowaste to biofuel. Furthermore, we do incorporation of practical experiment and theoretical calculation for better understanding of reaction mechanism that applied in energy system.
