Synergistic Effect of 1,4-Benzenedimethaneamine Assembled Graphene Supported Palladium for Formaldehyde Oxidation Reaction in Alkaline Media

Abstract

An electrochemical sensor based on 1,4-benzenedimethaneamine functionalized graphene supported palladium (GO-BDMA-Pd) nanoparticles (NPs) has been synthesized and employed as an efficient electrocatalyst for formaldehyde (HCHO) oxidation reaction (FOR). The physical characterization of the sensor has studied via transmission electron microscopy (TEM) and X-ray photoelectron spectroscopy (XPS). TEM study has revealed good dispersion of PdNPs onto the GO-BDMA surface. The electrochemical properties of the sensor for FOR have been studied by different electrochemical techniques including cyclic voltammetry, differential pulse voltammetry and chronoamperometry in 1 M KOH. The proposed sensor has shown high sensitivity, good stability and fast response to HCHO. The oxidation peak current has followed a linear relationship with the HCHO concentration in the range of 1 × 10 −6 -1.8 × 10 −2 M with limit of detection 3. In last few years, small organic molecules like acetic acid, methanol, ethanol and formaldehyde (HCHO) have gathered huge attention due to their potential applications in low temperature fuel cells.

Production of Liquid Solar Fuels and Their Use in Fuel Cells

“…196 Since then, such a formaldehyde fuel cell is no longer being further developed, although the catalysts of electrochemical oxidation of formate have been extensively studied. [197][198][199][200][201] Methanol Hydrogen Production from Methanol and Water Methanol can be used as a hydrogen storage material, because it is a liquid at room temperature, containing 12.6% hydrogen by weight. 202 Production of hydrogen from methanol by methanol reforming normally requires high temperatures (over 200 C) and high pressures (25-50 bar), which has precluded its practical application.…”
