A room-temperature synthesized NiFeCe₂ electrocatalyst delivered a current density of 10 mA cm⁻² at a cell voltage of 1.59 V when used as the electrolyzer.

Ternary spinel CuCo2O4 nanostructure clenches great potential as high-performance electrode material for next-generation energy storage systems because of its higher electrical conductivity and electrochemical activity. Carbon free and binder free 3D flower-like CuCo2O4 structure are grown on nickel foam (NF) via a facile hydrothermal synthesis method followed by annealing. The obtained CuCo2O4/NF is directly used as electrode for lithium ion batteries (LIBs) and supercapacitors (SCs) applicatio

In this study, the deep eutectic solvent (DES)-aided synthesis of γ-CoV2O6 under modest reaction conditions using 1:1 choline chloride–malonic acid was reported. In the presence of DES, the reaction occurred at a lower temperature (500 °C) compared with that of the respective conventional solid-state synthesis of metal oxides and also with the calcination process involving the metal salts, thereby decreasing the overall formation energy. Differential scanning calorimetry revealed a 2-fold decrea

This paper presents experimental and simulation studies to evaluate the feasibility of sequestering supercritical CO2 in depleted gas reservoirs. Experimental results were simulated to obtain gas-liquid relative permeability curves used in the field simulation study. A 3D simulation model of one-eighth of a five-spot pattern was constructed to evaluate injection of supercritical CO2 under typical field conditions.

Abstract Herein, we report the controlled and direct fabrication of Cu 2 O/CuO thin film on the conductive nickel foam using electrodeposition route for the electrochemical reduction of carbon dioxide (CO 2 ) to methanol. The electrocatalytic reduction was performed in CO 2 saturated aqueous solution consisting of KHCO 3 , pyridine and HCl at room temperature. CO 2 reduction was carried out at a constant potential of −1.3 V for 120 min to study the electrochemical performance of the prepared ele
