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

We developed a novel hybrid red-black phosphorus/sulfonated porous carbon (R-BP/SPC) compositeviaa 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.
