Tausch mtausch@uni-wuppertal.de 1 Didaktik der Chemie, Bergische Universit?t Wuppertal, 42119 Wuppertal, Germany Photocatalytic hydrogen production without the bypass via photovoltaics and electrolysis has been realized using a versatile photocatalytic system with only three components: the redox mediator ethyl viologen, the photocatalyst proflavin and the sacrificial donor EDTA. By adding a reduction catalyst made of nano-platinum on alumina to the aqueous solution of these three chemicals, hydrogen can be produced by irradiation with sunlight. http://pubs.sciepub.com/wjce/9/4/3/wjce-9-4-3.pdf photocatalyst redox mediator sacrificial donor reduction catalyst energy conversion energy carrier artificial photosynthesis sustainable development goals SDGs
