Tuning Electrode Surfaces to Optimize Solar Fuel Production
An electrode material with modified surface atoms generates more electrical current, which drives the sunlight-powered reactions that split water into oxygen and hydrogen a clean fuel
February 18, 2021
Through a tight coupling of experiment and theory, scientists showed at the atomic level how changes in the surface composition of a photoelectrode play a critical role in photoelectrochemical performance.
UPTON, NY Scientists have demonstrated that modifying the topmost layer of atoms on the surface of electrodes can have a remarkable impact on the activity of solar water splitting. As they reported in
Nature Energy on Feb. 18, bismuth vanadate electrodes with more bismuth on the surface (relative to vanadium) generate higher amounts of electrical current when they absorb energy from sunlight. This photocurrent drives the chemical reactions that split water into oxygen and hydrogen. The hydrogen can be stored fo
