MXenes　are　regarded　as　a　type　of　two-dimensional　(2D)　inorganic　material,　mainly　comprising　a　number　of　transition　metal　carbides,　nitrides,　or　carbonitrides　atomic　planes.　Nevertheless,　the　scientific　com-munity　is　continuously　interested　in　exploring　and　structuring　the　engineered-based　multifunctional　material　for　numerous　applications.　The　MXenes-based　materials　in　this　context,　have　emerged　as　highly　active　compounds　owing　to　their　superior　surface　area,　substantial　interlayer　spacing,　highly　reactive　surface-active　sites　and　surface　functional　group,　even　though,　recent　studies　have　shown　significant　scientific　and　theoretical　progress　related　to　enormous　prospects　in　MXenes,　chemical　nature,　robust　electrochemistry　and　high　hydrophilicity　of　MXenes.　The　role　of　MXenes　in　all　kinds　of　strategies　is　still　in　an　upgrading　phase　for　their　further　improvement,　and　is　not　sufficiently　summarized　in　the　literature　now.　To　begin　with　this,　herein,　present　review　article　is　intended　to　critically　discuss　the　diversity　of　MXenes　with　respect　to　different　composition,　formulation,　plasmonic,　complexation,　and　numerous　geometric　and　morphological　aspects,　along　with　novel　construction　strategies　to　improve　their　surface　characteristics　in　all　aforesaid　multidimensional　applications.　Following　that,　in　terms　of　broadening　the　application,　this　review　article　is　envisaged　to　endorse　the　use　of　MXenes　and　their　hybrid　configuration　in　a　series　of　emerging　environmental　decontamination　via　adsorption,　photodegradation,　photocatalytic　fuel　production　via　hydrogen　evolution,　CO2　reduction,　electrocatalytic　sensing,　along　with　membrane　distillation　and　energy　storage.　In　addition,　comprehensive　information　about　existing　obstacles　and　future　perspectives　have　been　addressed.　Finally,　an　overview　is　succinctly　summarized　and　discussed　regarding　the　emerging　prospects　of　MXenes　for　their　potential　uses　in　numerous　research　fields.　At　the　end,　it　is　anticipated　that　this　review　article　will　pave　the　way　for　the　effective　use　of　MXenes　in　different　fields　of　environmental　remediation,　energy　conversion,　storage　and　biomedical　applications　as　an　innovative,　reliable,　and　multifunctional　material.(c)　2022　Elsevier　Ltd.　All　rights　reserved.
