Heteroatom doping is an effective way to raise the electrochemical properties of carbon materials. In this paper, a novel electrode material including nitrogen, phosphorus, and sulfur co-doped pyrolyzed bacterial cellulose (N/P/S-PBC) nanofibers was produced. The morphologies, structure characteristics and electrochemical performances of the materials were investigated by Scanning electron microscopy, Fourier transform infrared spectra, X-ray diffraction patterns, X-ray photoelectronic spectroscopy, N2 sorption analysis and electrochemical measurements. When 3.9 atom% of nitrogen, 1.22 atom% of phosphorus and 0.6 atom% of sulfur co-doped into PBC, the specific capacitance of N/P/S-PBC at 1.0 A/g was 255 F/g and the N/P/S-PBC supercapacitors’ energy density at 1 A/g was 8.48 Wh/kg with a power density of 489.45 W/kg, which were better than those of the N/P-PBC and N/S-PBC supercapacitors. This material may be a very good candidate as the promising electrode materials for high-performance supercapacitors.

: Nanocellulose have attracted much research interests owing to its biocompatibility, low density, environmental sustainability, flexibility, ease of surface modification, excellent mechanical properties and ultrahigh surface areas. Recently, lots of research efforts have focused on nanocellulose-based conductive hydrogels for different practical applications, including electronic devices, energy storage, sensors, composites, tissue engineering and other biomedical applications. A wide variety of conductive hydrogels have been developed from nanocellulose, which can be in the form of cellulose nanofibers (CNF), cellulose nanocrystals (CNC) or bacterial cellulose (BC). This review presents the recent progresses in the development of nanocellulose-based conductive hydrogels, their advanced functions, including 3D printability, self-healing capacity and high mechanical performances, as well as applications of the conductive nanocellulose hydrogels.
