My research work was on the enhancement of conversion efficiency of carbon dioxide in millichannels and in photocatalytic reactor. This work has the application in the field of material synthesis, characterization and its application in various fields such as energy and environment. It involves two major studies of gas-liquid absorption and photocatalytic reduction of CO2. I designed and fabricated the milli channels and the photochemical reactor and synthesized the novel photo catalyst by modifying the Titanium dioxide (TiO2) nanotubes in order to improve the reduction of carbon dioxide to useful hydrocarbon fuels. Applied MATLAB to solve the mathematical models in mass transfer studies and gas-liquid hydrodynamics in millichannels. ACADEMIC BACKGROUND:
