Hydrogen peroxide is a valuable chemical used in various applications and there is a demand for small on-site production plants. An attractive way to produce hydrogen peroxide is by electrochemical reduction of oxygen, using electrocatalytic materials that favour formation of hydrogen peroxide instead of water. Oxygen reduction on carbon in alkaline solution is known to produce mainly hydrogen peroxide...
The potential of novel, carbon and nitrogen doped Ti-oxides for application as Pt-free catalyst for the oxygen reduction reaction (ORR) in polymer electrolyte fuel cell cathodes was systematically investigated in model studies under well defined reaction conditions. Ti oxide was prepared by a sol-gel process; doping of titania with N and C was performed via reactive incorporation during the sol-gel...
