  • Fujishima and Honda (1972) demonstrated the potential of titanium dioxide (TiO2) semiconductor materials to split water into hydrogen and oxygen in a photo-electrochemical cell. Their work triggered the development of semiconductor photocatalysis for a wide range of environmental and energy applications. One of the most significant scientific and commercial advances to date has been the development of visible light active (VLA) TiO2 photocatalytic materials. In this review, a background on TiO2 structure, properties and electronic properties in photocatalysis is presented.

  • Introduction: Today, the energy supply is primarily based on the combustion of fossil fuels. Electricity generation is the main driver for carbon dioxide emissions in stationary applications, whereas vehicles powered by internal combustion engines are a major source of distributed carbon dioxide emissions. The generation of electricity from renewable energy sources such as solar power, wind power, tidal power, or the use of biomass is reducing the burden from carbon dioxide emissions.

  • Electrical energy plays an important role in our daily life. It can universally be applied and easily be converted into light, heat or mechanical energy. A general problem, however, is that electrical energy can hardly be stored. Capacitors allow its direct storage, but the quantities are small, compared to the demand of most applications. In general, the storage of electrical energy requires its conversion into another form of energy.
