Theoretical investigation on the performance of simple and doped graphenes for the surface adsorption of various ions and water desalination

Robust and facile detection of formaldehyde through transition metals doped olympicene sensors: a step forward DFT investigation

“…18 With all these different types of solid materials have been used explored for sensing applications such as activated carbon, covalent organic framework, graphene, zeolites and metal organic framework. 19,20 These developed mechanisms were not too efficient due to low surface area of adsorbents that are not good enough to adsorb these gases. 21 The other most important drawback of using these adsorbents are that they produce harmful byproducts that are extremely dangerous materials.…”

Adsorption of Industrial Gases (CH4, CO2, and CO) on Olympicene: A DFT and CCSD(T) Investigation

“…Recently, carbon nanostructures have been extensively explored for their adsorption and sensing properties. 20 − 23 Already reported gas sensors for CO and CO 2 are Pt-doped armchair graphene nanoribbons and carbon nanotubes. 24 , 25 Different graphene-based materials have been studied for the detection of CO 2 and CO gases.…”

“…Therefore, different types of solid materials are employed as gas sensors to adsorb these toxic gases such as activated carbon, zeolites, metal–organic frameworks, graphene, and covalent organic frameworks. Recently, carbon nanostructures have been extensively explored for their adsorption and sensing properties. − Already reported gas sensors for CO and CO 2 are Pt-doped armchair graphene nanoribbons and carbon nanotubes. , Different graphene-based materials have been studied for the detection of CO 2 and CO gases . For methane gas, resistive gas sensors are used, but such sensors have poor conductivity at low temperature .…”
