Abstract

The advancement of extremely effective and long-lasting sustainable electrocatalysts developed from abundant earth elements is an emergence aspect in green energy generation. The greenly synthesised NCF-LDH has been shown that promising candidate for the OER process. Mechnochemical processes are often quick, inexpensive, and easily scalable to produce industrial quantities. In comparison with IrO₂ (370 mV), the optimum NCF-LDH-X on GC electrode showed the modest required overpotential (240 mV) at 10 mA cm⁻². Solar-assisted water oxidation at 1.57 V shows more expert efficacy of NCF-LDH-2 for solar to hydrogen generation. As an outcome, the greenly synthesised NCF-LDH outperformed the high-priced electrocatalysts. Consequently, low-cost industrial-scale H₂ generation using commercial solar cells might be possible.

绿色合成的 NCF-LDH 作为低电池电压下氧气进化反应的可持续电催化剂

从丰富的地球元素中开发出极为有效和持久的可持续电催化剂，是绿色能源生产的一个新兴方面。绿色合成的 NCF-LDH 已被证明是 OER 工艺的理想候选材料。机械化学工艺通常快速、廉价，而且易于扩展，可进行工业化生产。与 IrO2（370 mV）相比，GC 电极上的最佳 NCF-LDH-X 在 10 mA cm-2 时显示出适度的所需过电位（240 mV）。在 1.57 V 的太阳能辅助水氧化条件下，NCF-LDH-2 在太阳能制氢方面表现出更高的专业效能。因此，绿色合成的 NCF-LDH 优于价格昂贵的电催化剂。因此，利用商用太阳能电池进行低成本工业规模制氢也许是可能的。
