Account of Ni/NiO Nanoparticle-Supported N-Doped Graphitic Carbon Derived from Sugarcane Waste as a Sustainable Electrocatalyst for Oxygen Evolution Reaction

Abstract

The recent past has witnessed an exponential increase in the demand for energy conversion, storage, and consumption technologies. The development of inexpensive, efficient, durable electrode materials and catalysts is critical to the success of these technologies/devices. Here, we present a simple, sustainable, cost-effective, and scalable method for preparing stable and effective nickel/nickel oxide nanoparticles on highly porous Ndoped graphitic carbon. The catalysts were prepared by a direct pyrolysis method at different temperatures under an argon atmosphere. When compared to other catalysts, the carbon material synthesized at 800 °C

The controllable synthesis of NiO/Ni/C nanosheets via pulsed plasma in ethylene glycol solution for oxygen evolution electrocatalysis

“…Fig. 8f summarizes the performance of the EG30 prepared in this study compared to the NiO/Ni/C 8–10,38–44 and noble metal 45,46 previously reported in literature. Herein, we mainly compare overpotentials and Tafel slopes.…”

Plastic Chip Electrode: An Emerging Multipurpose Electrode Platform

“…KCl) and Platinum foil has been used as reference and counter electrodes respectively in all these experiments, whereas diverse methods have been tried for loading the electrocatalyst on PCE, based on its nature. Ru‐triazine COF, [51] Ni based MXene, [89] hierarchical nanostructure, [90] and Ni‐doped graphitic carbon based electrocatalysts [91] were loaded in the blends of nafion by drop casting. On the other hand, hierarchical polyoxometallate thin film has been directly picked up from the air‐water interface [73] .…”

Producing green hydrogen in an efficient way using a nexus of a waste-biomass derived catalyst and a cost-effective & scalable electrode platform

“…As we have reported in our previous report, sugarcane waste was used as a biomass precursor for the synthesis of graphitic carbon doped with nitrogen and Ni NPs were encapsulated with a graphitic shell giving good catalytic activity. 13…”

“…As we have reported in our previous report, sugarcane waste was used as a biomass precursor for the synthesis of graphitic carbon doped with nitrogen and Ni NPs were encapsulated with a graphitic shell giving good catalytic activity. 13 In this work, we report an electrochemical method for the production of green hydrogen using a combination of an innovative catalyst, electrolyte, and electrode platform. Among various catalysts developed, the Ni-based catalyst assures an acceptable high performance and low cost as compared to previous metal-based catalysts.…”
