Investigation of the Different Morphologies of Zinc Oxide (ZnO) in Cellulose/ZnO Hybrid Aerogel on the Photocatalytic Degradation Efficiency of Methyl Orange

A facile fabrication of zinc oxide‐doped carbon aerogel by cellulose extracted from coconut peat and sodium alginate for energy storage application

“…This phenomenon can be explained by increasing from 5 to 25 mg, the amount of cellulose converted to carbon also got higher, expanding the amorphous region in the ZCA samples. It is noteworthy that raising the cellulose content also led to the penetration of ZnO into different sites in the carbon matrix of the synthetic samples 17,25 . Hence, the crystallinity of ZnO decreases gradually, as shown in Figure 1b.…”

“…This was explained by the robust interactions between the ZnO and the CA matrix. 17 The XRD pattern was used to measure the crystallinity of pure cellulose and ZCA samples. For the cellulose, two broad peaks at about 16.3 and 22.5 are typically assigned for two characteristics of ( 110) and (200) diffractions, respectively, observed in the cellulose Iβ structure.…”

Fabrication of Carbon and Related Materials/Metal Hybrids and Composites

“…The composite that contains mesoporous silica layers within an encapsulating graphene nanosheet supported by an ultrafine metal was studied by Shang et al in 2014 [89], and was developed by Sarkar et al in 2019 [90] by changing metal uses with Cu. Besides producing the structure with the desire properties, their research is also trying to provide a catalyst which can be useful in chemical reactions.…”

“…As presented in Table 3, and as stated by the different reports, all hybrid systems showed higher surface areas than those of bare metal oxides. Highly dispersed ZnO NPs supported on the silica gel matrix 245 [89] Cellulose/ZnO hybrid aerogel (CA/ZnO) 352.82 [90] Wheat gliadin/ZnO hybrid nanospheres 523.88 [91] 3.5. AFM Topographical Analysis of the Synthesized Carbopol/ZnO Hybrid Nanoparticles Gel Figure 6a-d shows the non-contact mode topographical AFM 2D images and the corresponding 3D images for the synthesized Carbopol/ZnO hybrid nanoparticles gel.…”
