MATERIALS FOR PHOTOELECTROCATALYTIC HYDROGEN PRODUCTION
摘要：
The invention relates to the direct conversion of solar energy to chemical fuels, e.g. hydrogen, utilizing a combination of a visible and/or infrared light absorber with a non-platinum (Pt) hydrogen evolution reaction (HER) catalyst deposited on its surface. The invention discloses a hydrogen evolution reaction (HER) material comprising a molecular cluster core of the formula L x N y M z , where L is selected from molybdenum (Mo), tungsten (W), tantalum (Ta), rhenium (Re), iron (Fe), nickel (Ni), niobium (Nb), chromium (Cr) and cobalt (Co); N is selected from oxygen (O), nitrogen (N), sulphur (S), selenium (Se) and tellurium (Te); M is selected from copper (Cu), cobalt (Co), manganese (Mn), or any other transition metal; x is an integer selected from 2, 3, 4 and 5; y is an integer selected from 1, 2, 3, 4 and 5; z is an integer selected from 0, 1, 2, 3, 4 and 5. The invention further discloses a system comprising said HER material and a photoabsorptive positive type (p-type) semiconductor with a low band gap, where said HER material is positioned on the surface of said photoabsorptive semiconductor, thereby enhancing the hydrogen production.
