Research interests

In recent decades, significant endeavours have been dedicated in resolving the escalating energy and environmental problems which have raised to an alarming rate. Photocatalysis, a process which drives chemical transformations by harvesting solar light in the presence of a catalyst, has emerged as a promising route to address these challenges. This technology appeals to be sustainable and less energy consuming due to its prominent feature of utilizing inexhaustible solar energy as the main driving force. Our research activities primarily focus on the rational design of novel, robust nanostructured materials for the applications in solar energy production and environmental remediation, which include pollutants degradation, hydrogen and oxygen evolution by water splitting as well as carbon dioxide photoreduction into hydrocarbon fuels such as methane and methanol. These projects are funded by Science Fund (MOSTI), NanoMITe -LRGS and FRGS (MOHE).
