Effect of solvent on Se-modified ruthenium/carbon catalyst for oxygen reduction

Effect of solvent on Se-modified ruthenium/carbon catalyst for oxygen reduction

Se-modified ruthenium supporting on carbon (Sex–Ru/C) electrocatalyst was prepared by solvothermal one-step synthesis method. The reaction mechanism was revealed after discussing impact of different solvents (i-propanol and EG) in solvotermal reaction. The result showed that the grain size of Se-mod...
