Nitrogen adsorption isotherms on activated carbon fibers (ACFs) were measured at 77.3 K in the relative pressure range from 10(-7) to 0.995. The low relative pressure data are examined in detail in order to characterize the microporosity and the surface heterogeneity of the samples studied. The pore

## Abstract Polyacrylonitrile (PAN) hollow fibers were pretreated with ammonium dibasic phosphate aqueous solution, then further oxidized in air, carbonized in nitrogen, and activated with carbon dioxide. The effects of pretreatment concentration of ammonium dibasic phosphate aqueous solution on th
A series of activated carbon fibers (ACFs) and heat-treated oxidized ACFs prepared from phenolic fiber precursors have been studied to elucidate the role of pore size, pore surface chemistry and pore volume for the adsorption of SO, and its catalytic conversion to HZSOI. For untreated ACFs, the init
