Ag₂NCN anchored on Ti₃C₂T_xMXene as a Schottky heterojunction: enhanced visible light photocatalytic efficiency of rhodamine B degradation

Abstract

We prepared Ag2NCN/Ti3C2Tx by an electrostatically driven self-assembly process with excellent performance of Rh B degradation. The superior visible light absorption and Schottky junction, are responsible for the improved photocatalytic performance.

In situ synthesis of g-C3N4/Ti3C2Tx nano-heterostructures for enhanced photocatalytic H2 generation via water splitting

“…Hence, the nano-heterostructure of Ti 3 C 2 T x and g-C 3 N 4 can efficiently separate and transport the photo-induced electrons and holes, significantly improving the performance of the photocatalytic system. 85,86 This enhanced activity was observed for gCN-0.75, given that this was the optimal combination of g-C 3 N 4 and Ti 3 C 2 T x for the formation of the coupled catalyst system among the prepared compositions, as discussed in the previous section. 76 Furthermore, the stability and reusability of the catalyst were assessed using a recycling study of the most active sample for 3 cycles, i.e.…”

MXene/CdS photothermal–photocatalytic hydrogels for efficient solar water evaporation and synergistic degradation of VOC

“…The results show that Ti 3 C 2 only has slight photocatalytic activity under visible light, which is consistent with previous research results. 55 The photodegradation performance of all the MC composites was better than that of CdS or Ti 3 C 2 , which means that the combination of CdS and MXene can significantly improve the removal efficiency of RhB. When the ratio of Ti 3 C 2 to CdS changed from 2 : 1 to 1 : 1, the degradation rate of RhB increased and exceeded 95% after 120 min of irradiation.…”
