Hydrogels are 3D crosslinked hydrophilic polymer networks with a large quantity of water, [1][2][3] which have been applied to a wide range of fields such as chemical sensors, water treatment, human-machine interface, electronic skin, and biomedical engineering in recent decades. [4][5][6][7][8][9] However, the weak mechanical performances of hydrogels made a great challenge for their further applications. [10][11][12] With the exploration of advanced engineering methods and novel materials, as well as structural composition precision design and fillers, an increasing number of functional hydrogels with tunable properties have been prepared, which exhibited the desired mechanical, adhesive, and conductive properties for practical applications. [13][14][15][16][17] Among the functional hydrogels, adhesive hydrogels have attracted much attention for wound healing, soft tissue reconstruction, antibiosis, and wearable electronic devices. [18][19][20][21][22] The polymeric network of hydrogel connects to the substrate materials through covalent bonds, noncovalent complexes, polymer chains, and nanoparticles. A unifying principle has been demonstrated that strong hydrogel adhesion is achieved through the synergy of chemistry, topology, and mechanics. [23] Many strategies were developed to achieve strong adhesion, including the introduction of nanoparticles. [24,25] The nanoparticles can attach to polymer chains by physical or chemical interactions to form a network in nanocomposite hydrogels, which contribute to offering energy dissipation, lowering adhesion energy, and improving the mechanical property. [26] Besides that, some special functional groups on the nanoparticles are beneficial for hydrogel adhesion. [27] In contrast, the incorporation of nanofillers could improve the conductive, [28][29][30] self-healing, stimuli-responsive properties of hydrogels. [31,32] Many nanomaterials were used in nanocomposite adhesive hydrogels such as graphene oxide, [22] silica nanoparticles, [33] iron oxide, [34] and modified carbon nanotubes. [35] In recent years, MXenes-based nanocomposite adhesive hydrogels have attracted more attention. [36] MXenes are emerging 2D transition metal carbides and/or nitrides with a general formula of M nþ1 X n T x . [37][38][39] Ti 3 C 2 T x is the first reported kind of MXenes, which was fabricated by Naguib in 2011. [40] Recently, MXenes have been widely explored due to their remarkable hydrophilic, strong mechanical, and highly conductive properties, [41,42] as well as their high specific surface area and abundant surface-terminating functional groups. [43,44] The unique combination of properties makes MXenes as attractive candidates as nanofillers for nanocomposite

“…Initially, the carbonated beverages (an orange beverage with E110 dye and a pomegranate beverage with E122 dye) were degassed by leaving them in the air at 25 °C for 120 min. After being digested (which means the breakdown of unwanted substances in the sample) using acetic acid (4%), the strawberry and orange-flavored jelly was dissolved in DDW 53 , 54 . For E110 and E122, CS@CTAB (0.005 g) was introduced to each sample, and the optimum pH for each dye was set with constant shaking for 240 min.…”

In order to develop a novel and cost-effective adsorbent with outstanding adsorption capacity and excellent recyclability for anionic pollutants, the chitosan-modified cetyltrimethylammonium bromide sorbent (CS@CTAB) was fabricated. Fourier-transform infrared spectroscopy, N2 adsorption–desorption isotherm, elemental analysis, Thermogravimetric analysis, X-ray diffraction, and Scanning electron microscopy have been applied to evaluate both raw and surfactant modified chitosan (CS@CTAB). Azorubine, Sunset Yellow, and hexavalent chromium were used to study the adsorption behavior of CS@CTAB under various parameters such as adsorbent dose, initial dye and metal ion concentration, contact time, and temperature. Adsorption equilibrium, kinetics models and thermodynamic parameters were investigated. The adsorption isotherm fitted well with the Langmuir isotherm model, with a maximum adsorption capacity of 492.6 mg/g, 492.6 mg/g, and 490.196 mg/g for Azorubine, Sunset Yellow, and Hexavalent Chromium, respectively. The kinetic studies showed that the pseudo-second-order model provided a better correlation between experimental data. Furthermore, the calculated thermodynamic parameters confirmed that the adsorption of Cr(VI), E110, and E122 by CS@CTAB material is a spontaneous and exothermic process. The fabricated CS@CTAB adsorbent was employed for the efficient elimination of Azorubine, Sunset Yellow, and hexavalent chromium from real water samples, synthetic mixtures, and colored soft drinks, with a percentage of recovery of ~ 96%. The plausible adsorption mechanisms of Azorubine, Sunset Yellow, and hexavalent chromium on the surface of CS@CTAB are elucidated. The adsorption anticipated to be due to electrostatic interaction and hydrogen bond formation for hexavalent chromium; while the adsorption of Azorubine and Sunset Yellow, was assumed to be due to electrostatic interaction, hydrogen bonding, and n-π interaction. Finally, the study demonstrates the efficiency of CS@CTAB for the removal of anionic species from several samples, including natural water and colored beverages.

“…However, these methods are often inefficient at lower concentrations and can be expensive. Some techniques that were dynamically employed to remove food colorants are Fenton's oxidation process [30], membrane filtration, aerobic biotreatment [31], electrocoagulation [32], adsorption [33,34], and a few quantitative determination techniques such as electrochemical sensing [35,36]. Some of these methods require an additional separation system during the large-scale removal of these pollutants in discharges.…”

In this work, we synthesized a metal-free sulfonic functionalized graphitic carbon nitride using sulfuric acid through the wet impregnation technique. The functionalization of sulfonic groups (–SO3H) on g-C3N4 will promote a high surface charge density and charge separation owing to its high electronegativity. The g-C3N4–SO3H shows excellent optical/electronic and surface properties towards enhanced photo–redox reactions. The sulfonic groups also facilitate the availability of more separated charge carriers for photocatalytic oxidation and reduction reactions. The as-synthesized material has been characterized by different spectroscopic tools to confirm the presence of functionalized –SO3H groups and optoelectronic possessions. The photocatalytic responses of g-C3N4–SO3H result in 99.56% photoreduction of Cr (VI) and 99.61% photooxidation of Sunset Yellow FCF within 16 min and 20 min, respectively, of visible light irradiation. The g-C3N4–SO3H catalyst exhibits a high apparent rate constant (Kapp) towards the degradation of Cr (VI), and SSY, i.e., 0.783 min−1 and 0.706 min−1, respectively. The intense optical–electrochemical properties and potentially involved active species have been analyzed through transient photocurrent, electrochemical impedance, and scavenging studies. Consequently, the photocatalytic performances are studied under different reaction parameters, and the plausible photocatalytic mechanism is discussed based on the results.
