“…Carbon materials have the advantages of low density, excellent electrical conductivity, good biocompatibility, and high mechanical strength, which have been considered as one of the most attractive and valuable materials [132][133][134][135][136]. However, pure carbon materials have a narrow application range, owing to its strong hydrophobicity and limited active sites.…”

The increasing demand for monitoring the glucose concentration in the blood of diabetic patients has aroused the attention of researchers to prepare high-performance glucose biosensors. After decades of development, enzyme-based biosensors have gradually matured and commercialized, but they still suffer from insufficient stability due to the inherent defects of the enzyme. Non-enzymatic glucose sensor was proposed to address this issue. The introduction of nanotechnology has provided more possibilities for the preparation of highly efficient catalytic materials. Among the synthesized electrocatalysts, metal oxides are one of the most important components owing to their outstanding properties. Recent studies have integrated metal oxides with other materials to further improve sensor performance. This review focuses on the application of metal oxide-based hybrid structure in the glucose sensor, mainly including metal oxide/metal oxide, metal/metal oxide, and carbon material/metal oxide. The preparation method, electrochemical properties, and catalytic mechanism of the sensors are discussed in detail. Finally, we present some of the existing challenges and make personal predictions for the future development of non-enzymatic glucose sensors.

“…Therefore, they are hydrophilic, can be well dispersed in aqueous solutions. [24][25] These properties of GO and RGO have promising potential for environment-friendly and effective approaches in the fields of adsorption research. Arabpour et al [26] reported the effect of the synthesize reaction condition of GO, Ferreira et al [27] prepared RGO-zinc oxide (rGO-ZnO) composite, Jiang et al [28] constructed a cross-linked graphene aerogel, Rohaizad et al [29] synthesized silver nanoparticles from Catharanthus roseus (C. roseus) dried peels extract doped with GO, Calimli et al [30] used RGO-supported Ni nanoadsorbents for the removal of MB at the last manuscripts.…”

The adsorption of methylene blue (MB) on graphene‐based adsorbents was tested through the batch experimental method. Two types of graphene‐based adsorbents as graphene oxide (GO) and reduced graphene oxide (RGO) were compared to investigate the best adsorbent for MB removal. So that optimizing the MB removal for the selected type of graphene‐based adsorbent, the diverse experimental factors, as pH (2–10), contact time (0–1440 min), adsorbent dosage (0.5–2 g/L), and initial MB concentration (25–400 mg/L) were analyzed. The conclusions indicated that the MB removal rised with an increase in the initial concentration of the MB and so rises in the amount of adsorbent used and initial pH. Maximum dye removal was calculated as 99.11% at optimal conditions after 240 min. Adsorption data were compiled by the Langmuir isotherm (R2: 0.999) and pseudo‐second‐order kinetic models (R2: 0.999). The Langmuir isotherm model accepted that the homogeneous surface of the GO adsorbent covering with a single layer. And the adsorption energy was calculated as 9.38 kJ mol−1 according to the D‐R model indicating the chemical adsorption occurred. The results show that GO could be utilized for the treatment of dye‐contaminated aqueous solutions effectively.

“…Industrial wastewater recycling has become an increasingly more evident need. The efforts of international governments to safeguard the environment have contributed to private companies taking action on the matter and making important investments in these fields [1,2,[4][5][6][7][8][9][10][11][12][13][14][15][16][17][18]. The textile industry discharges organic and inorganic waste that produces bioaccumulation and can cause high degrees of toxicity [19] (Table 1, Figure 1).…”

Uses of Nanoclays and Adsorbents for Dye Recovery: A Textile Industry Review

et al. 2021

Wastewater recovery is one of the most pressing contaminant-related subjects in the textile industry. Many cleaning and recovery techniques have been applied in recent decades, from physical separation to chemical separation. This work reviews textile wastewater recovery by focusing on natural or synthetic nanoclays in order to compare their capabilities. Presently, a wide variety of nanoclays are available that can adsorb substances dissolved in water. This review summarizes and describes nanoclay modifications for different structures (laminar, tubular, etc.) to compare adsorption performance under the best conditions. This adsorbent capacity can be used in contaminant industries to recover water that can be used and be recontaminated during a second use to close the production circle. It explores and proposes future perspectives for the nanoclay hybrid compounds generated after certain cleaning steps. This is a critical review of works that have studied adsorption or desorption procedures for different nanoclay structures. Finally, it makes a future application proposal by taking into account the summarized pros and cons of each nanoclay. This work addresses contaminant reuse, where part of the employed dyes can be reused in printing or even dyeing processes, depending on the fixing capacity of the dye in the nanoclay, which is herein discussed.
