Oxygen evolution catalysts from hydrothermal synthesis Seminar

The use of mild hydrothermal synthesis conditions for the successful synthesis of condensed inorganic materials have been known for a good many years.[1] In this talk, I will discuss synthesis, crystal structure and physical properties of some new precious metal containing crystalline oxide materials which have been prepared using conventional hydrothermal synthesis procedures. Electrochemical characterisation of these materials has revealed promising electro catalytic behaviour towards oxygen evolution reaction (OER) in acidic medium.[2-3] The electrodes prepared from these materials show good stability and significant activity that could well be compared with commercially available catalysts such as crystalline solid solution between RuO2 and IrO2.
