Abstract
THE recently introduced method of using ultra-violet light to influence reversibly the electronic structure of semiconducting catalysts1–3 has been extended to a combination of the photovoltaic effect and a catalytic reaction. Illumination with ultra-violet light of thin layers of catalyst, supported on metal, changes the electron distribution in the catalyst reversibly by promoting electrons from the semiconductor into the metal. Other properties, such as porosity and surface area, are unaffected even though they may be changed in doping and alloying. Thus a new method is provided to investigate the relation between electronic structure on the one hand and kinetics and activation energy on the other for catalytic reactions on supported catalysts.
