The complexity of this problem may be somewhat simplified by considering that the net oxidation of CrIII(OH)3(s) to CrVIO42- by O2 yields a ∆Go equal to 0.92 kcal mol-1, on the basis of reported redox potentials (see above). The initial electron transfer ...

Water splitting
Water splitting is the general term for a chemical reaction in which water is separated into oxygen and hydrogen. Efficient and economical water splitting would be a key technology component of a hydrogen economy. Various techniques for water splitting have been issued in water splitting patents in the United States. In photosynthesis, water splitting donates electrons to power the electron transport chain in photosystem II.
