On the way to raising the technology readiness level of diamond electrolysis

During the last decades, hundreds of scientific papers have focused on use anodes consisting conductive diamond coatings, pointing out their outstanding capacity for mineralization organic pollutants contained in wastewater. Most works consist evaluation removal different types organics, with concentrations ranging from a few micrograms up to several grams per liter, matrices, synthetic solutions containing large sulfate or chloride real However, technology readiness level has been stagnant lab at levels 4–5 and, because promising results published, there is need raise values that indicate full-scale applicability. In this review, two main challenges be overcome reach higher are reviewed. The first improvement formulation doped coatings targeting tailored dedicated applications. Its significance explained terms high influence these anodic surfaces efficiencies degradation complex anthropogenic organics overall, efficient production oxidants, extend oxidation nearness anode surface bulk wastewater during electrolysis. second advantage design electrochemical cell integrates anode, trying take properties not only by improving mass transport rates but also optimizing combination its very paths other non-electrochemical mechanisms.
