In this work, chemical vapor deposition (CVD) using SBA-15 as the template at different temperatures ( 7501000 degrees C) was used for the fabrication of phosphorus-doped ordered mesoporous carbons (POMCs) for highperformance supercapacitors. The structural formation of the template and POMCs was confirmed using various characterization techniques. Furthermore, the magnetic characteristics of the POMCs were explored using room-temperature field-dependent magnetization studies. Moreover, the supercapacitor performance of the POMCs was evaluated through electrochemical analyses, such as cyclic voltammetry (CV), galvanostatic charge-discharge (GCD), and electrochemical impedance spectroscopy (EIS) in a 1 M H 2 SO 4 electrolyte medium. Among all POMCs, POMC 900 exhibited a high specific capacitance of 312 Fg - 1 at a current density of 0.5 Ag -1 due to a higher Phosphorus content. Furthermore, the symmetric device fabricated using POMC 900 showed 90.8 % coulombic efficiency with 97.5 % capacitance retention after 5000 cycles at 2 Ag -1 of the current density as well. Thus, the CVD synthesis of POMC materials is a highly promising electrode material for cheap and highperformance supercapacitors.
