Support interactive synthesis of nanostructured MoS 2 electrocatalyst for oxygen reduction reaction

Abstract Here, we report facile and novel hydrothermal approach for the synthesis of nanostructured molybdenum disulfide (MoS 2 ) using 3D mesoporous silica support. Observation of Raman bands E 1 2g and A 1g confirms the formation of layered MoS 2 sheets. Scanning electron and transmission electron microscopic analysis clearly portrays highly stacked MoS 2 sheets with vast edge sites. Stacking of MoS 2 sheets are found responsible for the formation of flower like structure. In application to electrochemistry, the nanostructured MoS 2 showed catalytic activity with a close four electron pathway in alkaline medium towards oxygen reduction reaction.
