Abstract
- Magnesium oxide (MgO)-supported nanocatalysts are a highly insulating crystalline solid with a sodium chloride crystal structure and excellent properties including chemical inertness, high temperature stability and high thermal conductivity. Here, a ternary alloy catalyst of MgO-supported CoMoB was synthesized by means of a chemical reduction method using ethylene glycol solution. The prepared CoMoB/MgO catalysts were characterized using x-ray diffraction, scanning electron microscopy (SEM/EDX) and Fourier transform infrared spectroscopic analysis. The CoMoB/MgO nanocomposite served as the enabling platform for a range of applications including hydrogen production catalyst and hydrogen peroxide (H<subscript>2</subscript>O<subscript>2</subscript>) determination. It also showed a high hydrogen production rate (1000 mLg<subscript>cat</subscript><superscript>−1</superscript> min<superscript>−1</superscript>) and low activation energy (68.319 kJ mol<superscript>−1</superscript>) for the hydrolysis of ammonia borane. Additionally, the electro-oxidation performance of the CoMoB/MgO for H<subscript>2</subscript>O<subscript>2</subscript> detection was studied by cyclic voltammetry and chronoamperometry. The CoMoB/MgO sensor demonstrated a wide linear range up to 10 mM with a detection limit of 3.3 μM. [ABSTRACT FROM AUTHOR]
