High performance nitrogen-doped porous carbon for supercapacitors, named as Gelatin–Mg–Zn-1 : 5 3, has been successfully prepared via a dual-template carbonization method, without any physical/chemical activation process, in which gelatin serves both carbon/nitrogen source, and low cost Mg(NO3)2·6H2O Zn(NO3)2·6H2O dual templates. It is revealed that the temperature, mass ratio of gelatin–Mg(NO3)2·6H2O–Zn(NO3)2·6H2O plays crucial role determination surface area, pore structure correlative...
Abstract Low‐cost activated carbons with high capacitive properties remain desirable for supercapacitor applications. Herein, a three‐dimensional scaffolding framework of porous carbon nanosheets (PCNSs) has been produced from typical biowaste, namely, ground cherry calyces, the specific composition and natural structures which have contributed to PCNSs having very large surface area 1612 m 2 g −1 , hierarchical pore size distribution, turbostratic structure degree graphitization, about 10 %...
Through a simple and convenient template carbonization method, nitrogen-doped porous carbon has been successfully achieved by heating urea formaldehyde (UF) resin magnesium citrate at 800 °C, where the serves as template. The mass ratio between UF plays crucial impact on surface areas, pore structures, correlative capacitive behaviors of final carbons, denoted samples UF-Mg-1:1, -1:3, -1:5. All present carbons exhibited amorphous features with low graphitization degrees. Sample UF-Mg-1:3...
A hard–soft dual templates method has been developed for the first time to prepare porous carbons by direct carbonization of phenol formaldehyde resins (PFs), Zn(NO3)2·6H2O and polyvinyl butyral (PVB) at 1000 °C under Ar gas, in which PFs serve as carbon source. More importantly, PVB acting hard soft template, respectively, can be readily removed through evaporation process, resulting pure without any post-treatment, commonly employed.
