Recently, natural biomass has been widely explored as a precursor to prepare carbon materials due to its abundant, low-cost, and renewable character. Herein, a series of high-performance heteroatom-doped carbons hase been successfully produced from natural biomass small molecular peach gum for the first time. The sheet-like O-doped carbons PG-C and HTC-PG-C are synthesized by pyrolyzing peach gum (PG) and hydrothermally treated peach gum (HTC-PG), respectively. The three-dimensional hierarchical porous O-doped carbons PG-AC, HTC-PG-AC, and N/O-codoped carbon HTC-NPG-AC are prepared via KOH activation of PG, HTC-PG, and a hydrothermally treated mixture of peach gum and 1,6-hexanediamine (HTC-NPG), respectively. The PG-C, HTC-PG-C, PG-AC, HTC-PG-AC, and HTC-NPG-AC possess specific surface areas of 274.3, 374.3, 1256, 1279, and 1535 m2 g–1, respectively. In particular, PG-C, HTC-PG-C, PG-AC, HTC-PG-AC, and HTC-NPG-AC exhibit excellent capacitances of 199, 223, 334, 322, and 406 F g–1 at 0.2 A g–1 in 6 M KOH ...
