Scientist have successfully produced hydrogen efficiently and also devised a system to make syngas. a mixture of CO and H2 to make products like ethanol. At the University of Cambridge they have made Artificial Leaf to convert CO2 to fuels like propanol and ethanol. The artificial leaf devise has a cathode composed of photovoltaic pervoskite and cobalt catalyst and anode made of photocatalyst bismuth vanadate. When the devise is immersed in water, bismuth vanadate absorbs sunlight and splits the water at the anode. At the cathode pervoskite generate electricity which drives the cobalt catalyst to reduce CO2 and produce syn gas.
