Devices made of readily available oxide and carbon-based materials can produce clean hydrogen from water over weeks — according to new research.
The findings, co-led by Dr Virgil Andrei, a Research Fellow at St John’s College, University of Cambridge, with academics at Imperial College London, could help overcome one of the key issues in solar fuel production, where current earth-abundant light-absorbing materials are limited through either their performance or stability.
Underexplored materials for light harvesting
Hydrogen fuel will play a critical role in the transition to full decarbonisation and reaching the UK’s goal of net-zero emissions by 2050...
