Hybrid carbon-based materials are in demand to achieve the desired activities various fields. However, such lack aqueous dispersibility or mechanical strength, which can be addressed by certain modifiers as surfactants, polymers, metal oxides, and deep eutectic solvents (DESs), among others. Dodecyl trimethylammonium bromide (DTAB) a typical DES (reline; choline chloride/urea, 1:2) have been employed conjunction with graphene oxide–titanium oxide nanocomposites (GO@TiO2 NCs) get advanced adsorbents (which characterized physicochemical techniques). A model hazardous dye, methylene blue (MB), was used study adsorption potential of above-developed material. The process optimized terms adsorbent dose, initial MB concentration, pH, contact time. Various kinetic isotherm models were analyze data. Pseudo-second-order kinetics (R2 = 0.999) has followed Langmuir 0.998). Kinetics revealed that 100% achieved DES-based NC (DES-GO@TiO2), is better than both DTAB-based (DT-GO@TiO2) pure pristine material (GO@TiO2). It proposed (reline) couples TiO2 on GO surface an alternative route drive from background. Adsorption data compared other similar reported adsorbents, it found developed shows ultrafast (the rate 222 μg per gram DES-GO@TiO2 1 s). sustainability economy repeating numerous cycles (up seven times) without losing efficiency. applied chemical industries where color coloring involved effluent. Further, greener DESs should order develop sustainable structure–performance relationship for safer environment.
