Abstract: The invention relates to a method for dissociating an aqueous solution which includes electrochemical oxidation of the aqueous solution in the presence of pulsed light, said pulsed light being generated from a first source of light energy with a predetermined pulse frequency value, using an enzyme composition based on a first enzyme complex PSII, isolated from a second enzyme complex PSI, with production of oxygen, free electrons and free protons in the aqueous solution, characterised in that said light energy has a variable energy value over time, said method also including a step of modulating said predetermined pulse frequency value of said pulsed light.
