Preparation of porous reduced graphene oxide using cellulose acetate for high performance capacitive desalination

Abstract

A three-dimensional porous graphene electrode is prepared by using cellulose acetate as a template. The electrode possesses ideal porous structure and large surface area, therefore resulting in high electrosorption capacity for CDI application.

Co-exfoliation and fabrication of graphene based microfibrillated cellulose composites – mechanical and thermal stability and functional conductive properties

“…Impact on potential adsorption differences due to the more open structure generated when using pure graphene remain at this stage a point of conjecture. Figure 12 Nitrogen adsorption/desorption isotherms of (A) MFC, RGO and graphite, and (B) MFC/graphene MFC/RGO composites with 0.5 and 9 wt% filler loading; the inserts show the pore size distribution The wide range of pore size distribution might suggest that the composites have potential for application in capacitive desalination technologies, for example 62 . Combination of the meso-and macropores improves the overall efficiency of the composite by enabling a high mass transfer to the mesopores as well as facilitating the formation of an electrical double-layer in the mesopores.…”

Gelatin-modified Mxene carbon aerogels for ammonium-perchlorate-catalyzed thermal decomposition

“…The current intercalators are cellulose and carbon nanotubes, 17–21 but the more desirable method is the second method, which is to design the structure of Mxene nanosheets and assemble the 2D structure into a 3D structure. 22,23 However, the function of the gelation of Mxene nanosheets is weak, and the freeze-drying of Mxene nanosheets aerogel by self-assembly alone will result in weak mechanical properties and will not be able to obtain a more complete 3D structure. 14…”

“…The current intercalators are cellulose and carbon nanotubes, [17][18][19][20][21] but the more desirable method is the second method, which is to design the structure of Mxene nanosheets and assemble the 2D structure into a 3D structure. 22,23 However, the function of the gelation of Mxene nanosheets is weak, and the freeze-drying of Mxene nanosheets aerogel by self-assembly alone will result in weak mechanical properties and will not be able to obtain a more complete 3D structure. 14 As a decomposition product of collagen, gelatin contains a large number of functional groups (amino and carboxyl groups), which can interact with inorganic fillers through van der Waals forces, hydrogen bonds, and electrostatic forces as the medium.…”
