Summary: This study investigates the potential application of nanocrystalline boron-doped diamond (BDD) electrodes in electrochemical reduction of carbon dioxide (CO2). The BDD electrodes were fabricated using two different chemical vapor deposition (CVD) techniques and their electrical, structural, and electrochemical characteristics were studied. Modification of the BDD layer crystallinity and morphology significantly altered the overall electrode structure and improved the selectivity of product formation during CO2 electroreduction. The nanocrystalline BDD electrodes with modified structure demonstrated higher faradaic efficiency towards the production of formic acid (HCOOH) compared to microcrystalline BDD cathodes. The findings provide a basis for further development of BDD electrodes with scalable and cost-effective synthesis.

Summary: Boron-doped diamond (BDD) is considered an excellent electrode material, with a specific surface area being a crucial factor in its electrocatalytic performance. A 3D BDD structure, Cu/W/BDD, showed significantly higher electrochemical active surface area compared to a 2D planar structure, resulting in enhanced efficiency in removing tetracycline hydrochloride (TCH) and total organic carbon (TOC). The energy consumption and fluid dynamics of the 3D structure were identified as key factors in its superior degradation performance.

Summary: Boron-doped diamond (BDD) electrodes are highly effective for anodic electrochemical oxidation of wastewater. However, during chloride electrolysis using BDD electrodes, higher concentrations of ClO3(-) and ClO4(-) were found to be biotoxic compared to other electrode materials. This study fabricated BDD electrodes with five different boron doping concentrations and conducted physical and electrochemical characterization. The results showed that decreasing boron concentration led to smaller diamond crystal size, lower oxygen evolution potential, lower charge transfer resistance, and larger electro-active surface area (EASA). Electrochemical oxidation experiments of NaCl solution were conducted to compare and discuss the product concentrations, current efficiencies, and energy consumptions. With increasing boron concentration, the minimum energy required for producing unit active chlorine initially decreased and then increased, similar trends were observed in the yields of ClO3(-) and ClO4(-). The lightly doped BDD (1.23 x 10(20) cm(-3)) exhibited low energy consumption, high yield of active chlorine (AC), and low yields of ClO3(-) and ClO4(-). Electrolysis of chlorine-containing organic wastewater further demonstrated the excellent performance of lightly doped BDD electrode.
