Nano-Catalysis is becoming a strategic field of science since it represents a new way to meet the challenges of energy and sustainability. These challenges are becoming the main concerns of the global vision of the societal challenges and world economy. Catalysis research became one of the most powerful tools to take on these challenges.
Nanocatalysis can help design catalysts with excellent activity, greater selectivity, and high stability. Their properties can easily be tuned by tailoring the size, shape, and morphology of the particular nanomaterial. In the nano-catalysis (NanoCat) laboratory, we are designing and synthesizing various nano-materials (silica, metal oxides, metals, MOF etc) with specific shapes, sizes and morphologies and then evaluating their use as a nano-catalysts for the development of sustainable protocols for various challenging processes like photocatalysis, CO2 capture and conversion to fine chemicals, environmental remediation as well as C-H activation, C-C coupling, oxidation, metathesis, hydrogenolysis, hydrogenation reactions.
A guiding hypothesis is that catalytic efficiency (activity, kinetics, selectivity and stability) can be controlled by tuning the morphology of nanomaterials/nanocatalysts. We aim to develop of novel nanomaterials as catalysts to tackle “climate change”.
