A City University of Hong Kong research team has successfully mediated poor charge carrier transport at low voltage by adding phosphorus to a metal oxide catalyst. Metal oxides are a promising catalyst for photoelectrochemical (PEC) water splitting to produce hydrogen as an alternative fuel. However, their effectiveness is restricted at low voltage. Adding phosphorus reduced […]

Ecole Polytechnique Fédérale de Lausanne chemical engineers have invented a solar-powered artificial leaf, built on a novel electrode which is transparent and porous. The artificial leaf is capable of harvesting water from the atmosphere for conversion into hydrogen fuel. The semiconductor-based technology is scalable and easy to prepare. The paper reporting the results has been […]
