An artificial leaf could be used to create a commonly-used flammable gas from just water, sunlight and carbon dioxide, scientists report.
Being developed at the University of Cambridge, the 'leaf' mimics photosynthesis, the process which plants use to gather energy. At present, the gas — dubbed 'synthetic gas', or 'syngas' — is produced by consuming fossil fuels.
However, the carbon-neutral solution devised by scientists could eventually be used to develop a sustainable liquid fuel that serves as an alternative to petrol.
