Electrocatalytic oxidation of methanol and ammonia on Nickel Niacin bio-MOF: a mechanistic investigation
The electrochemical oxidation of methanol (MeOH) and ammonia (NH3) plays a pivotal role in industrial applications and environmental management. MeOH and NH3 are considered valuable fuel sources for fuel cell technology, while NH3 is a notable pollutant in aquatic environments. This research highlights the successful electrochemical oxidation of MeOH and NH3 in an alkaline medium using a nickel niacin metal–organic framework (NiNA-MOF) embedded in a carbon paste electrode (CPE). The NiNA-MOF/CPE demonstrated remarkable stability, ~ 98.0% current retention for MeOH electrolysis, and an efficiency of ~ 99.0% for NH3 oxidation. The mechanisms of AOR, MOR, and oxidation of the mixture were elucidated through the identification of reaction products via collecting and derivatization, followed by their comprehensive characterization using gas chromatography-mass spectrometry (GC–MS) and spectrophotometric techniques. These findings underscore the potential of NiNA-MOF as a highly effective catalyst for electrochemical oxidation processes, offering promising applications in energy storage and environmental remediation.
期刊介绍：
The Journal of Solid State Electrochemistry is devoted to all aspects of solid-state chemistry and solid-state physics in electrochemistry.
The Journal of Solid State Electrochemistry publishes papers on all aspects of electrochemistry of solid compounds, including experimental and theoretical, basic and applied work. It equally publishes papers on the thermodynamics and kinetics of electrochemical reactions if at least one actively participating phase is solid. Also of interest are articles on the transport of ions and electrons in solids whenever these processes are relevant to electrochemical reactions and on the use of solid-state electrochemical reactions in the analysis of solids and their surfaces.
The journal covers solid-state electrochemistry and focusses on the following fields: mechanisms of solid-state electrochemical reactions, semiconductor electrochemistry, electrochemical batteries, accumulators and fuel cells, electrochemical mineral leaching, galvanic metal plating, electrochemical potential memory devices, solid-state electrochemical sensors, ion and electron transport in solid materials and polymers, electrocatalysis, photoelectrochemistry, corrosion of solid materials, solid-state electroanalysis, electrochemical machining of materials, electrochromism and electrochromic devices, new electrochemical solid-state synthesis.
The Journal of Solid State Electrochemistry makes the professional in research and industry aware of this swift progress and its importance for future developments and success in the above-mentioned fields.
