CHT401 Advanced Heterogeneous Catalysis

CH0001 Fundamental Aspects of Chemistry

Details of each module is available in course finder

  • Developing strategies for the synthesis of supported monometallic and bimetallic nanoparticles based catalysts
  • Catalyst development for CO2 utilization - synthesis of cyclic, dimethyl and poly carbonates.
  • Catalyst development for renewable feedstock valorisation (cellulose, hemicellulose and lignin)
  • Mechanistic investigation of catalytic processes using kinetic and in-situ spectroscopic methods.

Catalyst Synthesis Strategies

In this theme, we are interested in developing simple and effective strategies for the synthesis of supported monometallic and bimetallic nanoparticles based catalysts for various organic transformations including selective oxidation, selective hydrogenation/hydrogenolysis and hydrogen auto transfer reactions. The challenge is to prepare these catalysts with precise control over the size, composition and nanostructure / shape by tuning the synthesis parameters. We design new methodologies by combining aspects of material science, nanotechnology and catalyst characterisation. In another part of this theme, we aim to design heterogeneous catalysts that are active, stable and selective for the above-mentioned organic transformations.

Renewable Feedstock

In this theme, we aim to develop catalytic systems (supported metal, mixed metal oxides, polyoxometalates, zeolites, inorganic-organic hybrid) for the valorisation of renewable materials such as CO2, lignocellulosic biomass components (cellulose, hemicellulose and lignin). For the CO2 valorisation reactions, we aim to develop heterogeneous catalysts for the (a) synthesis of cyclic carbonates from epoxides and CO2, (b) transesterification of cyclic carbonates to prepare dimethyl carbonate and glycols and (c) synthesis of polycarbonates from epoxides and CO2.

Mechanistic Investigation

In this theme, we use in-situ spectroscopic, kinetic methodologies to understand the mechanism of catalytic reactions (oxidation, hydrogenation and hydrogen auto transfer reactions). We use this information in the catalyst development program to design more active and selective catalysts. For example, we used EPR spectroscopic method to understand the reason behind the formation of nearly 99% of benzaldehyde during the catalytic selective aerobic oxidation of benzyl alcohol in spite of the fact that benzaldehyde readily oxidises to benzoic acid at room temperature in air. We found that traces of benzyl alcohol (substrate) inhibit the oxidation of benzaldehyde by selectively quenching the radicals (Figure below).
