Electronic Structure Effect of PtCo Alloy with Adjustable Compositions for Efficient Methanol Electrooxidation

“…Currently, platinum-based alloys are well recognized as high-performance electrocatalysts for accelerating the sluggish MOR process. − However, the limited storage capacity and exorbitant cost of platinum continue to impede the widespread adoption of fuel cells. Moreover, Pt-based MOR catalysts encounter obstacles such as poor utilization efficiency, limited durability, and the harmful effects of surface intermediates like CO. − Consequently, the pivotal challenge in catalyst development for fuel cells lies in enhancing the utilization and effectiveness of Pt. − …”

Mesoporous Mo-doped PtBi intermetallic metallene superstructures to enable the complete electrooxidation of ethylene glycol

“…The presence of these C1 species (CO 2 , CO 3 2− , and HCO 3 − ) indicated that M-PtBiMo IMSs cleaved C–C bonds to achieve the desired 10-electron complete oxidation of EG while providing a higher energy conversion efficiency (CH 2 OH–CH 2 OH + 14OH − → 2CO 3 2− + 10H 2 O + 10e − ). 49,50 Notably, no CO ad signal was detected for M-PtBiMo IMSs, indicating that a CO-free direct pathway was realized. The proposed mechanism of the complete electrooxidation of ethylene glycol on M-PtBiMo IMSs in alkaline media is illustrated in Fig.…”

2D petal-like PdAg nanosheets promote efficient electrocatalytic oxidation of ethanol and methanol

“…7–9 Previous studies have demonstrated that Pd-based nanomaterials are favorable electrocatalysts for EOR and MOR. 10–12 Nonetheless, conventional Pd-based catalysts suffer from insufficient activity and poor operation durability, which still hinder their further utilization. Therefore, designing and synthesizing active and durable Pd-based catalysts is highly desired.…”
