title: The electrochemical oxidation of ammonia at boron-doped diamond electrodes exhibits analytically useful signals in aqueous solutions.
abstract: Boron-doped diamond electrodes are shown to exhibit well-defined analytically useful voltammetric signals for the electrochemical oxidation of ammonia in aqueous solutions in comparison to commonly used carbon based electrode substrates. Proof-of-concept is shown for the construction of a miniature amperometric ammonia gas sensor utilising conductive boron-doped diamond.
