Development of nano boron-doped diamond electrodes for environmental applications

Boron doped diamond (BDD) is an outstanding electrode material with unique electrocatalytic properties and excellent stability, relevant to electrochemical advanced oxidation processes electroanalytical techniques. From environmental sustainability viewpoint, BDD electrodes are comprised only of earth abundant elements (carbon, boron, oxygen). However, a major drawback the high manufacturing costs per unit surface area for when fabricated using chemical vapor deposition or comparable processes. nanoparticles can provide alternative process that reduces by over 1000-fold while also improving catalytic activity. Herein, we demonstrate nano-BDD be depositing on silicon substrate Nafion® ink-casting method. Scanning electron microscopy (SEM), Raman spectroscopy, Fourier transform infrared spectroscopy (FTIR) were used investigate structural morphological properties, which compared manufactured standard methods. Cyclic voltammetry measurements revealed similar both electrodes, broad “electrochemical window”, essential effective production ∙OH radicals without oxygen generation, providing energy-efficient approach degradation pollutants in water. The enabled investigated [Fe(CN)6]3-/4- redox probe. sensing as-prepared was studied Dopamine.
