Hybrid carbon-based materials are in demand to achieve the desired activities in various fields. However, such materials lack aqueous dispersibility or mechanical strength, which can be addressed by certain modifiers such as surfactants, polymers, metal oxides, and deep eutectic solvents (DESs), among others. Dodecyl trimethylammonium bromide (DTAB) and a typical DES (reline; choline chloride/urea, 1:2) have been employed in conjunction with graphene oxide−titanium oxide nanocomposites (GO@TiO 2 NCs) to get advanced adsorbents (which are characterized by various physicochemical techniques). A model hazardous dye, methylene blue (MB), was used to study the adsorption potential of the above-developed material. The process was optimized in terms of the adsorbent dose, initial MB concentration, pH, and contact time. Various kinetic and adsorption isotherm models were used to analyze the data. Pseudosecond-order kinetics (R 2 = 0.999) has been followed by the Langmuir adsorption isotherm (R 2 = 0.998). Kinetics revealed that 100% MB adsorption was achieved with DES-based NC (DES-GO@TiO 2 ), which is better than that with both DTAB-based (DT-GO@TiO 2 ) and pure pristine material (GO@TiO 2 ). It is proposed that DES (reline) couples TiO 2 on the GO surface with an alternative route to drive MB from an aqueous background. Adsorption data were compared with other similar reported adsorbents, and it was found that the developed DES-based advanced material shows ultrafast MB adsorption (the rate of adsorption has been found to be 222 μg MB per gram of DES-GO@TiO 2 in 1 s). The sustainability and economy of the adsorbent were revealed by repeating numerous adsorption cycles (up to seven times) without losing the adsorption efficiency. The study can be applied in various chemical industries where color or coloring material is involved in the effluent. Further, other similar greener DESs should be used in order to develop sustainable structure−performance relationship for a safer environment.

Choline chloride (ChCl) based binary and ternary deep eutectic solvents (DES) were evaluated for methylene green electropolymerization with oxalic acid (OA) and ethylene glycol (EG) as hydrogen bond donors. Binary DES ChCl:OA in molar ratios 1:1 and 2:1 and ChCl:EG 1:2 and ternary DES (tDES) in different molar ratios and percentages of water were evaluated. The highest polymer growth was in ChCl:OA:EG‐tDES with added water, that had a lower viscosity and higher ionic conductivity when associated with HCl as dopant. This enhanced the formation of more cation radicals and, consequently, more polymer formation. The PMG/MWCNT/GCE‐tDES sensor was successfully applied to the simultaneous determination of 5‐aminosalicylic acid (5‐ASA) and acetaminophen (APAP) by differential pulse voltammetry in the concentration range 2 µM ‐ 200 µM, with detection limits of 0.37 µM and 0.49 µM for 5‐ASA and APAP, respectively. The sensor demonstrated good repeatability, reproducibility and stability, and was successfully applied in pharmaceutical formulations.
