In the present study, SO<jats:sub>2<\/jats:sub> adsorption on different carbon nanomaterials namely carbon nanohorns (CNHs), multiwalled carbon nanotubes (MWNTs), single-walled carbon nanotubes (SWNTs) and vertically aligned carbon nanotubes (VACNTs) are investigated and compared against the adsorption characteristics of activated carbon and graphene oxide (GO). A comprehensive overview of the adsorption behavior of this family of carbon adsorbents is given for the first time. The relative influence of surface area and functional groups on the SO<jats:sub>2<\/jats:sub> adsorption characteristics is discussed. The isosteric heat of adsorption values are calculated to quantify the nature of the interaction between the SO<jats:sub>2<\/jats:sub> molecule and the adsorbent. Most importantly, while chemisorption is found to dominate the adsorption behavior in activated carbon, SO<jats:sub>2<\/jats:sub> adsorption on carbon nanomaterials occurs by a physisorption mechanism.<\/jats:p>","DOI":"10.3762\/bjnano.9.169","type":"journal-article","created":{"date-parts":[[2018,6,13]],"date-time":"2018-06-13T13:50:11Z","timestamp":1528897811000},"page":"1782-1792","source":"Crossref","is-referenced-by-count":27,"title":["SO<sub>2<\/sub>
