H2 Photoproduction Efficiency: Implications of the Reaction Mechanism as a Function of the Methanol/Water Mixture

The influence of the reaction pathway sacrificial molecule oxidation to generate hydrogen is here investigated for lean and rich methanol mixtures. Pt-TiO2 powders promoted or not with tin sulfide were used as catalysts. With help in situ infrared experiments under conditions, evolution was shown take place by hole-related steps, alkoxy carbon-centered species key radical species. study analyzed quantitatively fate chemical use photons absorbed solids quantum efficiency useful fraction observables. Within this framework, role component promote photoactivity interpreted, braiding photonic information.
