Well incorporation of carbon nanodots with silicon nanowire arrays featuring excellent photocatalytic performances

Abstract: Recently, silicon (Si) nanowires have been intensively applied for a wide range of optoelectronic applications. Nevertheless, rare explorations considering the photodegradation of organic pollutants based on Si nanowires were performed, and they still require vast improvement, in particular for their degradation efficiency. In this study, broad-band and high efficiency photocatalytic systems were demonstrated through the good incorporation of Si nanowires with highly fluorescent carbon nanodots. The photodegra… Show more

“…The discoloration rate (K 1 ) was evaluated as the slope of the time dependence of MO relative concentration in semilogarithmic scale [37][38][39][40]. In all the cases, an approximation by a first-order reaction Equation (5) resulted in an R 2 factor higher than 0.97.…”
