Ternary heteroatom (B, P, N) doped graphene for high-performance supercapacitors.

ABSTRACT: Batteries and supercapacitors have become essential energy storage solutions, valued for their compact design, lightweight nature, and rapid energy delivery. However, traditional carbon-based supercapacitors are hindered by low energy density and limited charge storage capacity. To overcome these limitations, efforts have focused on tailoring carbon materials through heteroatom doping. In this work boron, phosphorous and nitrogen ternary codoped graphene (BPNG) samples were synthesized. FESEM, Raman and XPS analysis confirmed the morphology, structural integrity and bonding environment of the synthesized samples. The incorporation of 1.08 at%, 0.34 at% and 6.94 at% of B, P, and N, respectively for the optimized BPNG sample was confirmed by XPS analysis. This sample demonstrated outstanding
