Abstract
The thermodynamic correlation between the input energy by the one-photon excitation of aluminum porphyrin species (<italic>E</italic><sub>00</sub>= 2.03 eV) and output energy for the splitting of two water molecules into H<sub>2</sub>O<sub>2</sub>and H<sub>2</sub>(2H<sub>2</sub>O → H<sub>2</sub>O<sub>2</sub>+ H<sub>2</sub>, Δ<italic>G</italic>= (3.54 eV)).
