Abstract
The bismuth-embedded columnar activated carbon (Bi-AC) composite was prepared by the method of self-reduction and investigated for trapping I2 and CH3I. Our findings showed that the bismuth-based compounds mainly existed as simple substance in Bi-AC. The elemental bismuth was regularly spherical in the shape, and mostly embedded on the surface of activated carbon, seldom inside of activated carbon. The capture capacities of I2 and CH3I by the Bi-AC composite was 569.0 ± 14.2 and 232.1 ± 17.7 mg/g, respectively, which was better than that of the commercial silver-based materials. I2 was trapped to form I5- and Bi(IO3)3, while CH3I was catalytically cleaved to form BiOI and I5-. The Bi-AC composite is expected be used as adsorbents of 129I to replace silver-based materials due to its high performance and low cost.
期刊介绍：
The journal provides an international medium for the publication of theoretical and experimental studies and reviews related to the electronic, electrochemical, ionic, magnetic, optical, and biosensing properties of solid state materials in bulk, thin film and particulate forms. Papers dealing with synthesis, processing, characterization, structure, physical properties and computational aspects of nano-crystalline, crystalline, amorphous and glassy forms of ceramics, semiconductors, layered insertion compounds, low-dimensional compounds and systems, fast-ion conductors, polymers and dielectrics are viewed as suitable for publication. Articles focused on nano-structured aspects of these advanced solid-state materials will also be considered suitable.
