“…1 shows the Raman spectrum of the hybrid electrode and pure BDD electrode. There is a sharp peak around 1334 cm À1 , slightly away from the characteristic signature of the diamond structure, 1332 cm À1 , revealing the presence of diamond [10]. The peak around 800 and 1000 cm À1 are attributed to Bi 2 MoO 6 crystal [26,27]; XRD analysis of BDD and the hybrid electrode was shown in Fig.…”
