Figure 3. Structural characterization of the as-prepared Pt-based bimetallic catalysts. (A) XRD patterns and (B-E) SEM images of of PtCo-S/MCS, PtFe-S/MCS, PtCu-S/MCS, and PtCo/MCS catalysts;(F) Comparison of pore size and BET specific surface area of MCS, PtCo-S/MCS, PtFe-S/MCS, and PtCu-S/MCS. MCS: mesoporous carbon nanospheres; XRD: X-ray diffraction; SEM: scanning electron microscopy; BET: Brunauer-Emmett-Teller.
