“…Furthermore, the photoelectrocatalytic efficiencies of RhB solution for the pristine WO 3 , SW-1, SW-2, and SW-3 are evaluated to 48, 74, 87, and 67%, respectively, after 50 min irradiation. The photoelectrodegradation rate constant (k) was used to compare the degradation rate among various photocatalysts, assuming that the pseudo-first-order reaction model ln(Co/C) = kt 62. As shown in Fig.11c, the kinetic model fits well with the data of the pristine WO 3 and SW series samples.…”
