| 中文摘要 | 採用高效且耐用的電催化劑在解決能源危機方面顯示出巨大的潛力，特別是在透過水分解生產氫氣和氧氣的應用中。在這項研究中，我們採用了一種簡單的水熱方法從水果廢料中製造氮摻雜碳點（NDCD）。隨後，我們將鈷鐵層狀雙氫氧化物（CoFe-LDH）和二硫化鉬（MoS2）與NDCDs集成，合成了包含CoFe-LDH/MoS2@NDCDs的複合材料。由此產生的 CoFe-LDH/MoS2@NDCD 具有高度多孔的沙玫瑰結構，有利於電子流動路徑。此外，這種奈米複合材料具有更大、更開放的表面積，從而降低了阻力。簡化的電子路徑和改善的電解質擴散有助於在 HER 和 OER 中實現出色的催化性能；以最小的過電勢實現了 10 mA cm-2 的電流密度。此複合材料的固有活性（包括 TOF 和比活性）證明了其對 HER 和 OER 具有卓越的電催化性能。此外，透過計時電位法證實，合成的 CoFe-LDH/MoS2@NDCDs 複合材料在 24 小時內表現出增強的穩定性。這項研究驗證了 CoFe-LDH/MoS2@NDCDs 複合材料的有效性，將其定位為引人注目的水分解反應電催化劑。 |
| 英文摘要 | Employing highly efficient and durable electrocatalysts shows considerable potential in tackling the energy crisis, especially in applications concerning the production of both H2 and O2 via water splitting. In this research, we adopted a simple hydrothermal method to create nitrogen-doped carbon dots (NDCDs) from fruit waste. Subsequently, we synthesized a composite material comprising CoFe-LDH/MoS2@NDCDs by integrating a cobalt-iron layered double hydroxide (CoFe-LDH) and molybdenum disulfide (MoS2) with the NDCDs. The resulting CoFe-LDH/MoS2@NDCDs featured a highly porous sandrose structure that facilitates electron flow pathways. Additionally, this nanocomposite had a larger and more open surface area, reducing resistance. The streamlined electron pathways and improved electrolyte diffusion contributed to outstanding catalytic performance in both the HER and OER; a current density of 10 mA cm⁻2 was achieved with minimal overpotentials. The intrinsic activities, including the TOF and specific activity, of the composite demonstrated its remarkable electrocatalytic performance for the HER and OER. Furthermore, the synthesized CoFe-LDH/MoS2@NDCDs composite demonstrated enhanced stability for 24 h, as confirmed by chronopotentiometry. This study validates the effectiveness of the CoFe-LDH/MoS2@NDCDs composite, positioning it as a compelling electrocatalyst for water splitting reactions. |
