MXene & MXene composite
Maxenes, a new class of 2D transition metal carbides, nitrides, or carbonitrides, have emerged as game-changers in nanomaterials science. MXene-based composites, including those integrated with carbon, polymers, or metal nanoparticles, demonstrate enhanced stability, selectivity, and multifunctionality.
Metal oxide
Metal oxides are well-known for their stability, tunable band gaps, and redox-active nature, making them vital in energy conversion, catalysis, and sensing. These materials have shown exceptional performance in electrocatalysis (HER, OER, ORR), batteries, supercapacitors, and environmental remediation. Our research focuses on innovative synthesis routes and nanostructuring of metal oxides to push the boundaries of sustainable and high-performance materials.

Hybrids/Composites Nanomaterials
To improve the catalytic performance, the nanostructured catalyst requires supporting material with high conductivity and large surface area. It not only enhances the catalytic activity but also provides stability by preventing the extensive aggregation of nanoparticles. We made our effort to develop variety of hybrids/composites of nanomaterials on graphene, SnO2 or mesoporosus silca with Noble metals, Metal oxides based materials for their synergistic promising applications of interest. For examples, Graphene hybrids of Graphene-(Mn3O4, Pt, Pd, Au/Pd, Au@Pd, Porous Pd, Au@Porous Pd, Vo2D, MoS2, NiCo2O4, ZnCo2O4, Ag nanowires) Pt-SnO2, AgNPs-Mesoporous silica, Au-ZnO and etc.
