Reduction of Carbon dioxide – Photo-catalytic Route to Solar Fuels

Abstract

Abstract The motivation for this presentation is to examine why photo-catalytic reduction of carbon dioxide to fuel precursors and fuels has not yielded the desired levels of activity in spite of the intense pace of research in the recent years? Main issues namely, the relevance of residual carbon for the reduction products, inadequacy of analysis techniques existing, partial nature of the measures used to denote the activity and also suitably adjusting (increasing) the reducing power of the excited electron, have been identified, even though there may be other reasons for this disappointing progress. The remedial measures suggested may facilitate the progress in realizing this process as a viable one.
