CHEMICAL REACTIONS TO CONVERT SOLAR ENERGY INTO POWER SOURCES

Abstract

Photochemical synthesis of H2O2 and the combined thermal-photochemical decomposition were studied for the ultimate possibility of using sunlight for regenerative electrolytic cells, or for the purpose of making H202 for other high energy applications. Theoretical analysis of the photolysis and thermal decomposition of SO3 strongly indicated that a combination of a photochemical and thermal decomposition would not yield a decomposition greater than the 2 processes used separately. H2O2 synthesis was accomplished in both liquid and gaseous states using cadmium telluride and zinc oxide as photocatalyst. Without organic additives in the liquid phase, neither catalyst shows any promise. In the presence of the additives, the reactions are always exothermic and consequently of no value for energy conversion. (Author)
