Our research focuses on the innovative synthesis of a wide range of nanomaterials, including Perovskites, Semiconductors, Plasmonic oxides, metal-semiconductor composites, and polymer composites. We aim to harness the unique properties of these materials for impactful applications in the fields of Energy and the Environment.

Our core objectives include the strategic, bottom-up synthesis of nanomaterials using advanced wet chemical techniques. We tailor these materials to optimize their fundamental properties for specific applications, such as Surface-Enhanced Raman Scattering (SERS), sensing technologies, heterogeneous catalysis, photocatalysis, water splitting, and optoelectronics. Through this approach, we strive to develop cutting-edge solutions to address global energy and environmental challenges.
