Title : Heterogeneous Catalysis for Conversion of Carbon Dioxide to Formic Acid


Heterogeneous catalysis proffers the potential advantage of easy separation and recycling of the catalyst and easy purification of the products where as it`s counter part homogeneous catalysis although affords the advantages of high conversion and selectivity but lacks efficient recyclability of the costly metal catalysts. Carbon dioxide, a potent greenhouse gas produced mainly through the combustion of fossil fuels and deforestation, is drastically contributing to global warming, climate change and pollution.  One of the attractive ways is to convert it into useful chemicals due to its availability as plenty, cheap and non-toxic C-1 resource specifically for formic acid as it is a renewable energy storage for H2 gas. Formic acid is an essential intermediate and chemical feedstock because of it`s important applications in textile, dyeing, paper, medicinal agents, tanning agent, preservative agent and in livestock feed. The currently established and practised commercial process for the synthesis of formic acid is in two steps, comprising toxic carbon monoxide at high pressure and high temperature. To avoid the use of toxic carbon monoxide, the promising and potential replacement for the production of formic acid is the direct hydrogenation of very abundant, inexpensive and nontoxic CO2 using various transition metal based homogeneous and heterogeneous catalyst. Hydrogenation of CO2 to formic acid is mostly reported under homogeneous conditions by metal based catalysts additionally using liquid base, in which the transfer of the proton to the base favors the reaction. It was conceptualized to use metal and hydrotalcite as solid soft base and support as well, to heterogenise the homogeneous catalyat systems. Rhodium, ruthenium and copper based heterogeneous catalysts using hydrotalcite as support as well as base are synthesized, characterized and had been investigated in detail for the effective conversion of  CO2 to formic acid at moderate, temperature and total pressure of CO2 and hydrogen. Activity,selectivity and recyclability of these catalysts were appreciable for the production of formic acid under the employed reaction conditions in the auto clave.  My speech will discuss the above advances made in the recent research and developments for the atom economic conversion of CO2 to formic acid.


Ram Sambhar Shukla worked as Research Scientist in my whole career in the institute, CSIR-Central Salt and Marine Chemicals Research Institute (CSMCRI), Bhavnagar, Gujarat, India,  since 13th June 1983 to perform investigations on the Research and Development of the catalysis for various organic transformations. During my Ph. D., I had performed investigations on ruthenium catalyzed oxidation of organic compounds which had formed the basis of my importance to perform the research in the demanding area , which I had focused and performed on metal complexes based homogeneous and heterogeneous catalyst systems for environmentally and industrially important organic transformations using gaseous molecules, molecular oxygen, carbon monoxide, carbon dioxide and methane for their value addition and widening the scope of their utilization in organic transformations. I had been actively engaged in the research and development activities since 13th June 1983 in the research projects of national/international/network/collaborative status and still actively contributing to research and development. I had been faculty (Professor Dr. Ram Sambhar Shukla) of Academy of Scientific and Innovative Research (AcSIR). I had been teaching the Ph.D. course to the Research Scholars of, AcSIR of CSIR-CSMCRI, and Chemistry Department of Bhavnagar University, Bhavnagar. I had been taught to M.Sc. Chemistry students of Bhavnagar University, Bhavnagar.
