“…Maximum oxygen reduction peak current was provided by the BDD deposition onto the glassy carbon, with the lowest background signal in dimethyl sulfoxide (DMSO) solution. Heights of cathodic and anodic peaks were increased with the addition of a little amount of oxygen which is due to the conversion of O 2 to superoxide anion on the BDD electrode (Figure ) . The reduction of oxygen at BDD surface involved the 1e − reduction of oxygen to superoxide with a detection limit of 0.3 mg L −1 …”

The chemical stability and electrocatalytic properties of boron‐doped diamond (BDD) electrodes give rise to various applications. While wastewater treatment is the most widely studied field, the use of BDD for soil remediation and environmental sensing is currently investigated more and more. With regards to soil remediation, promising results have been reported for the treatment of soil washing solutions. Anodic oxidation using BDD at high current density allows high mineralization rates of biorefractory soil pollutants and extracting agents to be reached. At low current density, selective degradation of target pollutants has been achieved, thus allowing the reuse of extracting agents for further soil washing steps. BDD‐based electrochemical sensors have been studied for chemical oxygen demand determination, pesticide/pharmaceutical detection as well as other applications such as pH, O2 and analysis of various organic and inorganic compounds. Low detection limits, wide linear ranges and low standard deviations have been achieved. The main reasons behind the superiority of BDD sensors are the chemical stability, wide applicability and resistance of BDD towards biofouling. The beauty of BDD sensing is that it can work for a variety of organic and inorganic compounds under many physicochemical parameters.

Electrochemical tuning of the activity and structure of a copper-cobalt micro-nano film on a gold electrode, and its application to the determination of glucose and of Chemical Oxygen Demand

Micro-nano structured Cu-Co was in situ fabricated on the surface of a gold electrode via electrochemical reduction of CuCl2 and Co(NO3)2. It is shown that the shape of the particles can be controlled by variation of deposition current, deposition time, pH value and the ratio of Cu(II) and Co(II) ions. If prepared under current of −200 μA in 0.1 M, pH 4.0 acetate buffer solution, the film possesses high catalytic activity towards the electrochemical oxidation of glucose at a largely increased oxidation current compared to a non-modified surface. The electrochemical activity of this sensor can be easily tuned. Glucose is a standard compound for evaluating the chemical oxygen demand (COD), and we have therefore studied the application of the sensor to the determination of this parameter. Under optimized conditions, the sensor has linear response to glucose in the 1.92-768 mg L−1 concentration range, and the detection limit is 0.609 mg L−1 (at an S/N ratio of 3). A large number of surface water samples was studied, and the results obtained by this method were found to be linearly correlated to those obtained by the dichromate method (r = 0.995; n = 33).Graphical AbstractThis study describes the facile synthesis of micro-nano Cu-Co by one-step electrodeposition of Cu(II) and Co(II) on gold electrode. The alloy composite exhibited excellent electrocatalytic activities, and was successfully applied on the COD determination of glucose and water samples.Electronic supplementary materialThe online version of this article (doi:10.1007/s00604-014-1353-z) contains supplementary material, which is available to authorized users.
