Ni-based catalyst supported on mesostructured silica nanoparticles (MSN) for methanol oxidation reaction (MOR)

A new catalyst based on mesostructured silica nanoparticle (5wt%, 20wt%, and 30wt% Ni-MSN) were prepared by the wet impregnation method and used for electro-oxidation of methanol. While, MSN as a catalyst support was synthesized using co-condensation and sol-gel method. The synthesized MSN and N...
