Nb2CTx@MoS2 composite as a highly efficient catalyst for the degradation of organic dyes

Abstract

Here, Nb2CTx@MoS2 composites have been synthesized and their catalytic activity towards the reduction of organic dyes was evaluated. The Nb2CTx@MoS2 composite has been synthesized in different ratios (25, 50, and 75%) and it was found that Nb2CTx@50MoS2 (50% MoS2) was the best composite, as it was able to achieve complete reduction of methylene blue and methyl orange within 3 and 4 min, with rate constant of 0.55305 min−1, and 0.371 min−1, respectively. In addition, the catalyst was able to retain 86% of activity even after the 5 consecutive cycles.
