proposing that the pseudocapacitance is induced to the greater extent due to the presence of three heteroatoms such as N, P and O. This result is also supported by the fact that the Rct value of NPOMC electrode is found to be 1.17 Ω which is lesser than NOMC and POMC . Very recently, we have also studied the supercapacitive performance of B-doped OMC having boron level of 0.15 at. % and its method of synthesis is same as that of P-doped OMC except here the heteroatom precursor used is triisopropyl borate . The B-doped OMC achieved the gravimetric capacitance of 297 F g -1 at 0. ethylenediamine and triethyl phosphate at 90 °C for 6 h and the successive pyrolysis at 650 °C for 5 h followed by etching with 10 wt% HF . The NPOMC delivered the gravimetric capacitance of 183 F g -1 at 1 A g -1 in 1 M H2SO4 along with 94% of capacitance retained after 10000 cycles at 5 A g -1 . The value of capacitance in NPOMC is higher than those of NOMC (118 F g -1 ) and POMC (92 F g -1 ) suggesting that the increased capacitance in NPOMC is attributed to the presence of doped heteroatoms such as N (10.9 at. %) and P (3.6 at. %).
