Biobased chitosan hybrid aerogels with superior adsorption: Role of graphene oxide in CO2 capture

Synthesis and characterization of hybrid composite aerogels from alginic acid and graphene oxide

“…Alginic acid is cheap, abundant and can be easily gelated. On the other hand, graphene oxide is a flat molecule with numerous oxygen-containing functionalities, which has a high surface area and acts as a nanofiller [12]. The aerogels formed from this study is promising as it can be used as an adsorbent for different applications.…”

“…The hydrogel was synthesized by a sol-gel method similar to that of Rassis et al [14] but modified to incorporate the addition of GO as in the method of Alhwaige et al [12].…”

Graphene-Based Polymer Nanocomposites: Materials for Future Revolution

“…Based on these interactions, graphene based polymer nanocomposites have three different structures: phase separated, intercalated and exfoliated (Figure 1b). Excellent properties of graphene based Volume 1 Issue 3 -2017 polymer nanocomposites originating from these different kinds of interactions, endows its applications in photovoltaic cells [4,5], supercapacitors [6], Li ion batteries [7], electronic devices, protective coating, antibacterial coating and composites [8], fire retardant composites [9,10], biomedical applications, sensors, water purification, carbon dioxide capture [11], etc.…”

“…Various porous materials are being used to capture CO 2 , one important addition in this is graphene and graphene based materials. Porous composite aerogel made with biodegradable polymer like chitosan and GO can be used for this purpose [11].…”

Preparation of Chitosan Beads for the Adsorption of Reactive Blue 4 from Aqueous Solutions

“…Chitosan is a heterogeneous, linear, cationic and polysaccharide biopolymer with a high molecular weight [6]. The applications of chitosan as an adsorbent in form of flakes are limited by their high crystallinity, low surface area, nonporosity, resistance to mass transfer and low adsorption capacity [7].…”
