Ru dopants induced tensile strain in Ni₂P for efficient urea-assisted water decomposition at an ampere-level current density

Abstract

Ru-Ni2P@CN was synthesized by 'hydrothermal reaction-Ru solution impregnation-phosphating' using Vb12 as nitrogen source and carbon source. In addition, a large amount of Ru doping and tensile strain were successfully introduced into the catalyst.

Optimized Fabrication of Supercapacitor Using MOF-Derived NiCo2O4 with Porous Carbon as Cathode: Electrochemical Characterization and Stability Analysis using Time Series Analysis Technique

“…Supercapacitors (SCs) are distinguished for their rapid charge–discharge capability, prolonged lifespan, environmentally benign properties, high energy density, and power density, making them extensively functional across automotive, industrial, consumer electronics, energy, and other sectors. − To align with market demands, there is an imperative need to develop solid-state SCs with optimized components, specifically electrolytes, current collectors (featuring suitable electrode active materials), and separators. − However, conventional SCs utilize heavy electrodes, wherein most of the electrode active materials serve as dead volume due to lower porosity. , Additionally, alongside such electrodes, organic electrolytes are utilized to achieve a wide operating potential window (∼2.7 V) . Despite this, in comparison to aqueous substitutes, they are costly and flammable and some are toxic, rendering them unsuitable for portable and wearable electronic applications. , …”
