Polyoxometalate multi-electron-transfer catalytic systems for water splitting [PDF]

, 2014
The viable production of solar fuels requires a visible-light-absorbing unit, a H2O (or CO2) reduction catalyst (WRC), and a water oxidation catalyst (WOC) that work in tandem to split water or reduce CO2 with H2O rapidly, selectively, and for long ...
