Artificial photosynthesis to provide solutions for carbon capture and conversion:


Context:

Researchers from the Jawaharlal Nehru Centre for Advanced Scientific Research (JNCASR) have developed an integrated system that can capture carbon dioxide (CO2) and convert it into solar fuel.

  • They have named this process as artificial photosynthesis (AP) — which they feel can aid mitigate effects of emissions made by use of fossil fuels.

How it works?

This artificial photosynthesis (AP) harnesses solar energy and converts the captured carbon dioxide to carbon monoxide (CO) (using a photosensitizer), which can be used as a fuel for internal combustion engines.

  • Here, scientists are essentially conducting the same fundamental process in natural photosynthesis but with simpler nanostructures.
  • This process of converting CO2 into solar fuel also generates oxygen from water.
