Bifunctional TiO<sub>2 </sub>– cellulose based nanocomposites for synergistic adsorptive-photocatalytic removal of methyl orange: Response modelling and optimization
<p dir="ltr">Removal of azo dyes from aquatic environments represents a global challenge. Herein, by utilizing the waste of mandarin peels as a cellulose source (MP500), a bifunctional adsorbent-photocatalyst, TiO<sub>2</sub>@MP500, has been prepared via a one-pot hydroth...

| description | <p dir="ltr">Removal of azo dyes from aquatic environments represents a global challenge. Herein, by utilizing the waste of mandarin peels as a cellulose source (MP500), a bifunctional adsorbent-photocatalyst, TiO<sub>2</sub>@MP500, has been prepared via a one-pot hydrothermal synthesis. Taking advantage of this dual role, remediation of methyl orange (MO) has been successfully addressed. Characterization tools corroborated the anchoring of TiO<sub>2</sub> and the successful synthesis of TiO2<sub>2</sub>@MP500. SEM/EDX/TEM analyses confirmed the formation of TiO<sub>2</sub> nanoparticles on the carbonaceous surface. A substantial increase in the BET surface area following TiO<sub>2</sub> impregnation was perceived (184.61 m<sup>2</sup>/g in the case of 3 %TiO<sub>2</sub>@MP500). Similarly, the thermal stability of the developed composite was notably improved as reflected by the thermogravimetric analysis. XRD analysis corroborated the existence of carbonaceous layer with anatase phase TiO<sub>2</sub>. Optimization of the adsorbent-photocatalyst performance was approached using the Box-Behnken design. Five factors were premeditated, pH of the MO solution, adsorbent dose, reaction time, the concentration of TiO<sub>2</sub>, and [MO]. A maximum sorption capacity of 104.2 mg/g was reckoned, with a pseudo-second-order isotherm. Furthermore, the 3 %TiO2@MP500 achieved a decolorization efficiency of 98.87 % in ~30 min. The 3 %TiO<sub>2</sub>@MP500 nanocomposite was effectively revived and could be exploited for 6 cycles, bolstering a decolorization efficiency of 90.91 %.</p><h2>Other Information</h2><p dir="ltr">Published in: International Journal of Biological Macromolecules<br>License: <a href="http://creativecommons.org/licenses/by/4.0/" target="_blank">http://creativecommons.org/licenses/by/4.0/</a><br>See article on publisher's website: <a href="https://dx.doi.org/10.1016/j.ijbiomac.2025.141753" target="_blank">https://dx.doi.org/10.1016/j.ijbiomac.2025.141753</a></p> |
