Abstract
scan rate, and suggested that defect concentration can be used to tune the rate capability. Overall, we have demonstrated that using Cr as a sacrificial element in the MAX phase is a simple and effective strategy for the defect engineering of MXenes. Moreover, this method can likely be extended to include other sacrificial elements and MAX phases, making MXene defect engineering a viable pathway for property enhancement across various applications, including energy storage and catalysis.
