Fabrication of a boron-doped nanocrystalline diamond grown on an WC–Co electrode for degradation of phenol

Abstract

WC–Co is applied as the substrate instead of conventional ones, on which nanocrystalline BDD films are deposited by HFCVD. WC–Co/BDD electrode like the standard BDD shows a wide potential window and a good mineralization capacity in phenol.

Electrochemical decarboxylation of acetic acid on boron-doped diamond and platinum-functionalised electrodes for pyrolysis-oil treatment

“…In addition, the scattering intensity at 488 cm −1 and 1216 cm −1 decreases, corresponding to the weak band due to metallic and non-metallic impurities. Considering that the signal at 488 cm −1 is due to the boron doping level and vibration modes of boron clusters and pairs, 19,42 Raman analysis suggests that the concentration of boron in the diamond lattice decreases with electrolysis. Degradation of BDD can occur by either boron leaching or the graphitization of carbon at the grain boundaries.…”

“…18 Boron-doped diamond (BDD) has been used as a substrate material for deposition of metal nanoparticles used in sensing and degradation applications. [19][20][21] In particular, BDD is widely used due to its inertness towards poisoning within a wide potential window and high stability at high current densities. [22][23][24][25] For example, excessive polarisation of BDD for 250 hours in 1 M H 2 SO 4 at 1 A cm −2 resulted in no sign of etching, 26 conrming the stability of BDD.…”

Perspectiva de la oxidación electroquímica de colorantes sintéticos en aguas residuales artificiales: Rol del material anódico

“…Por tanto, se aproximan en gran medida al electrodo inactivo ideal [65] . Adicionalmente, es bien conocido que entre más escasa sea la interacción con los radicales adsorbidos, la reactividad anódica es mayor, es decir, la reacción química ocurre a mayor velocidad.…”

Progress in the Preparation of Metal Oxide Electrodes for the Electrochemical Treatment of Organic Wastewater: A Short Review

“…Furthermore, these electrodes exhibit low mechanical strength and are vulnerable to physical damage and chemical erosion, leading to unstable sewage treatment outcomes and the need for frequent replacement. Considering the limitations of current fabrication technologies, despite their excellent catalytic performance and lifespan, boron-doped diamond (BDD) electrodes still have the disadvantages of complex preparation processes and high costs [57][58][59]. These drawbacks add to the challenges and long-term operating costs of using carbon-based electrodes.…”
