Cover Picture: KOH‐Activated Porous Carbons Derived from Chestnut Shell with Superior Capacitive Performance (Chin. J. Chem. 11/2016)

The cover picture shows the preparation of porous carbons (PC) by using a waste biomass named chestnut shell via a two-step method involving carbonization and KOH activation. The as-prepared carbons were doped with multiple elements such as nitrogen, oxygen and sulfur, which can enhance electrical properties of the activated porous carbons. Moreover, the as-prepared carbon materials with high surface area and porous structure showed high capacitance performance and good rate capability. Meanwhile, the pore structures, surface area and electrochemical properties could be changed with the increasing of the KOH dosage. More details are discussed in the article by Xing and Zhuo et al. on page 1093–1102.
