[1023]. The XPS analysis of NPG/g-C3N4 revealed N content with 8.6 at. %. The electrochemical performance of NPG/g-C3N4 was tested using three electrode cell arrangement in 0.5 M Na2SO4 aqueous electrolyte. The NPG/g-C3N4 electrode delivered the specific capacitance of 440 F g -1 at 2 A g -1 , and retained 98% after 10000 cycles. Moreover, the effect of bending upon supercapacitor performance of NPG/g-C3N4 was investigated at three bending angles such as 45˚, 75˚, and 90˚. The exposure of the active sites by bending deformation created large addition pseudo-capacitance behaviour and improved the specific capacitance upto 948 F g -1 at 2 A g -1 . The excellent supercapacitive performances of the composite are owing to the unique hybrid structure, high surface area, more active sites and high interfacial interaction between NPG and g-C3N4.
