WebbThe conversion of solar energy could potentially be achieved based on splitting water into hydrogen and oxygen over semiconductor photocatalysts driven by sunlight [ 3, 4 ]. The hydrogen resulting from the water reduction reaction could then be used in fuel cells and serve as an important feedstock in chemical industries. Webbto split water into hydrogen and oxygen; ΔG as a useful work and TSΔ as a thermal energy. The Δ−GT diagram for the water splitting reaction is shown in Figure 2. The water decomposition reaction has a large positive free energy change and a small positive entropy change, as can be seen in Figure 2. Thus, the equilibrium for the
