摘要：Boron-doped ordered mesoporous carbons (B-OMCs) were prepared via solvent evaporation induced self-assembly (EISA) method by using triblock copolymer (Pluronic F127) as a soft template and boron modified phenolic resins as both boron and carbon precursors. The effect of molar ratio of formaldehyde to phenol (F/P) on the microstructure and character of B-OMCs was especially investigated. The results show that the specific surface area of B-OMCs increases along with the increase of F/P, while pore size and boron content of B-OMCs increase at first, then drop off. The material prepared with F/P = 1.5/1 possesses best-ordered mesostructure, higher specific surface area (667 m(2) g(-1)), larger pore size (7.9 nm), and highest boron content (1.26 wt%). And it also exhibits superior electrochemical performances and high specific capacitance (180 F g(-1)).
