主　　题：MXene Ti3C2Tx High yield Pseudocapacitor Precursor size Flake size 

摘      要：Ti3C2Tx,a most studied member of MXene family,shows promise as a candidate electrode for pseudocapacitor due to its electronic conductivity and hydrophilic ***,the unsatisfactory yield of Ti3C2Tx few-layer flakes significantly restricted it in real ***,we proposed a simple solution to boost the yield of Ti3C2Tx few-layer flakes by decreasing precursor *** using the small500 mesh Ti3AlC2 powders as raw material,high yield of 65%was successfully ***,the asreceived small flakes also exhibit an enhanced pseudocapacior performance owing to their excellent electrical conductivity,expanded inte rlayer space and more O content on the *** work not only sheds light on the cost effective mass production of Ti3C2Tx few-layer flakes,but also provides an efficient solution for the design of MXene electrodes with high pseudocapacior performance.
