The direct conversion of nickel-iron salts into a porous nickel-iron hydroxide supported N-doped carbon hybrid catalyst for enhanced urea oxidation reaction is a promising approach. Porous hybrid catalyst is utilized for heavy metal removal and organic dye adsorption. Urea oxidation reaction (UOR), on the other hand, is constrained by 6-electron transfer process and high amount of catalyst. For the time being, precious metal based catalyst are being used to solve these issue. However, the main difficulties are high potential, low reaction rate, and lack of catalyst stability. Given these constraints, our primary goal is to substitute this precious metal catalyst by forming porous hybrid catalyst from easily available nickel-iron salts by optimizing the reaction conditions. Interestingly, a significant improvement in UOR was found under normal conditions due to its porous structure and strong interaction between active sites of catalysts and urea molecule. |
