New Cu(I)-Based p-Type Semiconducting Metal Oxides for Solar-to-Fuel Conversion: Investigation and Challenges

摘要: The search for more efficient visible light materials solar-driven hydrogen production has brought metal oxides into the of renewed scientific attention due to its high stability. Traditionally various n-type have been studied photoelectrochemical cell (PEC) application as a photoanode such TiO2, because low cost, high-corrosion resistance, and suitable band structure (for UV light). More efforts are focused on development active semiconducting oxides, while very few p-type known solar-to-fuel conversion. fact that semiconductor actually acting photocathode in cell, which generates hydrogen, encourages us investigate new challenges associated with it. emphasis this chapter will be strategies make main focus copper-based (copper niobates copper tantalates), respect structure–property relationship, dopant effect, electronic calculations using density state (DOS).
