Greenly synthesised NCF-LDH as a sustainable electrocatalyst for oxygen evolution reaction with low cell voltage

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.
