Major Contributions
 

1. Showed that graphene quantum dots (GQD) encode a built-in, localized lattice distortion into a high-entropy Prussian blue analog (HEPBA), turning microstrain into an operando stabilizing function for alkaline hydrogen evolution.

2. In situ XAS and Raman revealed that the pre-built microstrain “locks” the Co–C≡N bridge, suppressing electrolyte-induced coordination disorder and sustaining framework-mediated charge transport; DFT shows more favorable H₂O adsorption and regulated H* energetics.

3. HEPBA/GQD reaches 207 mV at 100 mA cm⁻² in 1.0 M KOH and operates stably at 500 mA cm⁻² for 72 h, establishing microstrain-enabled stabilization as a pathway to robust coordination electrocatalysts.

主要貢獻
 

1. 證明石墨烯量子點（GQD）可在高熵普魯士藍類似物（HEPBA）中植入局部晶格扭曲，使微應變成為鹼性析氫反應中穩定結構的機制。

2. 臨場 X 光吸收光譜與拉曼光譜顯示，預建的微應變「鎖住」Co–C≡N 橋鍵，抑制電解液引起的配位失序並維持骨架電荷傳輸；DFT 計算顯示水分子吸附更有利、H* 吸附能獲得調控。

3. HEPBA/GQD 在 1.0 M KOH 中於 100 mA cm⁻² 的過電位為 207 mV，並在 500 mA cm⁻² 穩定運轉 72 小時，顯示以微應變穩定配位型電催化劑的可行途徑。
