Abstract:
The present disclosure relates generally to the field of artificial photosynthesis. More particularly, the present disclosure provides an artificial photosynthesis device and  a process for fabrication thereof. Aspects of the present disclosure also provide a photocatalytic material and a process for production thereof. Further aspect of the  present disclosure relates to a process for production of C1/C2 compounds from CO2 and H2O with the help of the artificial photosynthesis device with a solar to fuel  efficiency of 14.7 %. (Figure 1 A and 1 B).

ADVANTAGES
  • Simple and efficient method for conversion of mixture of carbon dioxide and water to value added liquid and gaseous chemicals in direct sunlight with economically viable artificial leaf device with a combined solar to fuel efficiency of 14.7%. 
  • Multi-functional photoanode was prepared by assembling ionic-precursors and converting them to light-absorbing photocatalyst quantum dots and concurrent electronic and structural integration in the micro and mesopores of wide band gap semiconductor is provided.
  • Concurrent activation of carbon dioxide and water to value added chemicals in direct sunlight is demonstrated by batch and semi-continuous processes.
  • Methanol and ethanol are major liquid products, and there are handles to fine tune selectivity of them.
  • Significant increase in process and catalyst temperature due to solar irradiation enhances the rate of reaction at no cost.
  • Entire reaction aspect can be carried out with different light sources, such as direct sunlight, standard laboratory light sources, UV, UV+Visible light sources.
  • Product selectivity and conversion efficiency can be tuned by employing different co-catalyst.
