Facile sonochemical assisted synthesis of a hybrid red–black phosphorus/sulfonated porous carbon composite for high-performance supercapacitors

Abstract

We developed a novel hybrid red–black phosphorus/sulfonated porous carbon (R–BP/SPC) composite via a simple sonochemical process, which can be used as a high-performance supercapacitor electrode that delivers a high specific capacitance of 364.5 F g⁻¹ at 0.5 A g⁻¹ with excellent cycling stability of 89% after 10 000 cycles in comparison to the previously reported BP electrodes.
