Environmental　issues　such　as　the　wastewater　have　influenced　each　aspect　of　our　lives.　Coupling　the　existing　remediation　solutions　with　exploring　new　functional　carbon　nanomaterials　(e.g.,　carbon　nanotubes,　graphene　oxide,　graphene)　by　various　perspectives　shall　open　up　a　new　venue　to　understand　the　environmental　issues,　phenomenon　and　find　out　the　ways　to　get　along　with　the　nature.　This　review　makes　an　attempt　to　provide　an　overview　of　potential　environmental　remediation　solutions　to　the　diverse　challenges　happening　by　using　low-dimensional　carbon　nanomaterials　and　their　composites　as　adsorbents,　catalysts　or　catalysts　support　towards　for　the　social　sustainability.
