Abstract

Hydrogen fuel is a kind of clean energy that can be generated by photo catalyzing water splitting. It is interesting to investigate the case contrasting to Gibbs free energy determination formula (GFEDF). Through calculation and theoretical analysis, results are: (1) there is not electric energy and other form of work consumed in photo catalyzing water splitting, hence, the work from outside environment is less than the change of Gibbs free energy; contracting to GFEDF. (2) GFEDF works with a reaction when absorbed heat is less than the heat for entropy change; GFEDF does not work with a reaction when absorbed heat is more than the heat for entropy change. Thereby, work is not always more than the change of Gibbs free energy to make a nonspontaneous reaction occur.
