Improved MnO based electrode performance arising from step by step heat treatment during electrodeposition of MnO for determination of paracetamol, 4-aminophenol, and 4-nitrophenol.

The design of electrochemical sensors is crucial considering important factors such as efficiency, low cost, biocompatibility, and availability. Manganese oxides are readily available, low-cost, and biocompatible materials, but their low conductivity limits their efficiency as sensors. Today, morphology engineering of manganese oxide has been one of the most common research topics, because manganese oxides' electrochemical properties are highly dependent on their morphologies.
