Interfacial Electron‐Modulated Pt Sites on Self‐Supported NiCoP Nanosheets for Enhancing Hydrogen Evolution Reaction

open access: yesCarbon Energy, EarlyView.
Using a hierarchical multilevel‐structure strategy, we design and prepare a self‐supported Pt/NiCoP/CF catalyst with a strong electron transfer effect between Pt and NiCoP. This catalyst realizes highly efficient HER performance under full pH range, outperforming commercial Pt/C catalyst.

Fe Atoms Accelerator Coupled With Oxygen Vacancies Channel Synergistically Boost OER Performance of Fe‐CoMoO4‐Ov Nanosheets

open access: yesCarbon Energy, EarlyView.
Fe‐CoMoO4‐Ov/NF demonstrates significantly improved OER catalytic performance compared to CoMoO4. Specifically, the introduced Fe atoms act as a promoter for surface reconstruction, significantly reducing the energy required for surface reconstruction to generate FeCoOOH. The oxygen vacancies serve as electron channels between the core Fe‐CoMoO4‐Ov and

The Stability of a PtRu/C Electrocatalyst at Anode Potentials in a Direct Methanol Fuel Cell

open access: yesJournal of Power Sources, 2006
Potential-scan tests were conducted to evaluate the stability of a PtRu/C electrocatalyst at anode potentials in a direct methanol fuel cell (DMFC). The results show that, under normal operating conditions, the anode potential in a DMFC is benign for the
