Structurally crosslinked HEC/ECH–MnO₂ nanocomposite as a sustainable green catalyst for the synthesis of symmetric bis-thiazoles featuring diphenoxyalkane linkers
Crosslinked hydroxyethyl cellulose/epichlorohydrin MnO₂ (HEC/ECH–MnO₂) nanocomposite films were prepared by in situ solution-casting of MnO₂ nanoparticles into a crosslinked (HEC) with (ECH) at five loadings (5–25 wt.%). MnO₂ nanoparticles were chosen for their availability, low cost, and redox-active Mn 2 ⁺/Mn 3...
