    • 目前，以鉑 (Pt) 被認為是 HER 最有效的觸媒。但是，豐度低、成本高，限制了它的廣泛應用性。
    在此領域中，研究出最佳替代 Pt 的產氫觸媒是最吸引人的題目。近期研究發現過渡金屬硫族化合物可作為 HER 的貴金屬催化劑的替代物。然而，過渡金屬二硫族化物的不良導電性可能限制其 HER 性能。
    利用電化學方法，通過簡易且低成本的方法，合成新型硫化聚丙烯腈衍生的 FeS2-PAN 複合物。然而在電化學反應過程中，如供給的電壓大小，會造成硫化鐵形成不同形態，進而影響硫化鐵的產氫效率；經過表徵、電化學分析和轉換率 (turn over frequency, TOF) 的計算，顯示 FeS2-PAN 電催化劑有 HER 活性的潛力。

    Currently, Pt-based materials are regarded as the most efficient electrocatalysts for HER. However, the low abundance and high cost limit their widespread applications. Providing a promising replacement to the Pt-based electrocatalysts became an exciting issue in this field.

    Recently, transition metals chalcogenides had been studied as an alternative to replace the precious metal catalysts for HER. However, poor conductivity for transition metal dichalcogenides may limit its HER performance.

    In this study, conductive polyacrylonitrile was first used and its sulfurized derivative (S-PAN) was applied as the precursor. Due to different valence state of sulfur, various preparation and electrochemical conditions were investigated to produce sulfurized polyacrylonitrile derived FeS2-PAN composite.

    Novel sulfurized polyacrylonitrile derived FeS2-PAN composite has been proposed and synthesized by electrochemical approaches. After structural and electrochemical characterizations, calculated turnover frequency, as-prepared FeS2-PAN electrocatalyst has shown promising HER activities.
