A research group in Osaka University have developed a novel photo catalyst that is free of metal which shows visible and near infrared light guided hydrogen production from water.
Hydrogen is the most amply found element in the world, and is thought by many to be a probable clean fuel over the coming years. Fossil fuels and water contain excessive amounts of hydrogen, but unwinding the molecular level dihydrogen fuel from these resources requires a large amount of energy. This has been casting uncertainty over any future of the hydrogen economy. Converting water into hydrogen with the help of solar energy could direct the road to clean and cheap hydrogen fuel. However, this procedure presently relies on the photo catalysts which contain costlier precious metal that restricts it capacity.
Now the research group at Osaka University have developed a fresh type of photo catalysts for hydrogen production using water, which is not only clear of costly metals but also absorbs the solar energy at a wider range than it used to previously. This research group have reported their findings in the recent publication in the ‘Journal of the American Chemical Society.’
The lead author of this publication Tetsuro Majima have expressed his excitement about the quantity of the hydrogen produced from water with the help of these newly developed photo catalysts with black phosphorous and carbon nitride. He also expressed his surprise when the research group found out that even after supplying low energy light, in the spectrum near to infrared, the photo catalysts were still able to produce hydrogen.
