Carbon emissions and rising temperatures are giving rise to the global crisis is no longer a new phenomenon. Also, stringent efforts are being taken worldwide to combat the hazards of global warmings by resorting to energy conservation methods and the use of alternative fuels.
IISc Bengaluru research team led by Biswajit Bhattacharya has recently achieved a breakthrough. Biswajit Bhattacharya is a Ph.D. scholar at the IISc Bengaluru. He and his colleagues have come up with the invention of an artificial leaf. This artificial leaf possesses the caliber to replicate photosynthetic process much more efficiently than the natural photosynthetic process. Also, the uniqueness of the artificial leaf resides in its capabilities to absorb the atmospheric carbon dioxide and exploit it for making bio-fuel.
This research study marks its presence in the American Chemical Society Journal. The paper was published in the journal on June 1, 2018. Biswajit Bhattacharya himself authored the scientific article. His achievements were not only restricted at this junction of American Chemical Society Journal, but he received the patent for his discovery too. Biswajit is overwhelmed by his contributions and says, “It feels great to have contributed towards this.”
Mechanism of the artificial leaf working:
While explaining the mechanism of artificial leaf Biswajit explains, “Basically, for photosynthesis or the process of plants taking in carbon dioxide to produce oxygen and glucose. For this process to happen, a high energy photon, electron, and sunlight are needed. The electron needs to have a lot of kinetic energy.”
The research team led by Biswajit created a semiconductor from the combination of copper aluminum sulfate and zinc sulfide. This semiconductor fulfills all the essential requirements of absorbing the sunlight. The absorbed sunlight gets converted into energy. This led to the foundation for their zest to replicate the process of photosynthesis.
During their research, the team came across the fact that the quantum leaf possesses a better energy conservation rate as compared to the regular leaf. This energy was then harnessed for the production of sulfate format bio-fuel. This bio-fuel allows hundred percent combustion. Also, it also recycles the carbon emissions.
