Fabrication of Ti3CN @ ZnSe nanocomposite for enhanced supercapacitor performance

In this work we have reported the synthesis of the composite of Ti3CN MXene with ZnSe nanoparticles. The as prepared composite materials were characterized by FTIR, p-XRD, SEM, EDS, and XPS. The prepared Ti3CN@ZnSe (1:1) nanocomposite showed excellent performance as an electrode material for supercapcitor applications. The Ti3CN@ZnSe (1:1) electrode showed the specific capacitance of 375 F g−1 at the current density of 1 A g−1. The material also retains ∼74.6% of capacitance after 4000 cycles of charge and discharge. The kinetic analysis was performed to give insight into the mechanism of charge storage and it was found that the charge storage was primarily controlled by diffusion process. Overall, the synthesized nanocomposite showed excellent peroformacne for potential application in supercapacitors.
