A team of scientists from Harvard University (United States) has created a unique bionic leaf that uses sunlight (solar energy) to split water molecules into oxygen and hydrogen and hydrogen-eating bacteria to produce liquid fuels from CO2.
This artificial photosynthesis device has been dubbed bionic leaf 2.0. The new system can convert solar energy to biomass with 10% efficiency.
Its efficiency is much higher than the 1% seen in the fastest growing plants. Scientists had used a new cobalt-phosphorous alloy catalyst for this experiment in order to increase efficiency.
The catalyst chemical design allows the system to self-heal i.e. doesn’t allow material to leech into solution.
Significance
This artificial photosynthesis system can be used to generate usable fuels.
This artificial leaf use solar power to split water and make hydrogen fuel.
