Major Contributions

1. Successfully developed a novel surface restructuring strategy using N-doped graphene quantum dots (NGQD) to modify Prussian blue analog-derived CoFe phosphides, achieving remarkable hydrogen evolution reaction (HER) performance with an overpotential of 70 mV at 10 mA cm⁻² in 0.5 M H₂SO₄.

2. Demonstrated through X-ray absorption spectroscopy that NGQD effectively induced electron density changes in Co atoms, leading to enhanced conductivity and electroactivity of the catalyst material.

3. Achieved exceptional stability under high current density conditions, maintaining performance at 600 mA cm⁻² for 12 continuous hours of operation, making it a viable alternative to conventional Pt-based catalysts.


主要貢獻

1. 成功開發了一種使用氮摻雜石墨烯量子點進行表面重構的新策略，用於改質普魯士藍類比物衍生的鈷鐵磷化物，在0.5 M硫酸中實現了優異的析氫反應性能，在10 mA cm⁻²時過電位僅為70 mV。

2. 通過X射線吸收光譜證明氮摻雜石墨烯量子點能有效誘導鈷原子的電子密度變化，從而提高催化材料的導電性和電活性。

3. 在高電流密度條件下實現了卓越的穩定性，可在600 mA cm⁻²的電流密度下持續運行12小時而保持性能，使其成為傳統鉑基催化劑的可行替代品。
