Synthesis of bimetallic Co–Pt/cellulose nanocomposites for catalytic reduction of p-nitrophenol

Abstract

The sonochemical synthesis of Co–Pt nanoparticles anchored on cellulose nanofibers (CNFs) was demonstrated. An enhancement in the catalytic activity of the synthesized Co–Pt/CNF nanocomposite catalyst was observed for the reduction of p-NP due to synergy effects.

Catalytic Reduction of 4-Nitrophenol to 4-Aminophenol Using Ag@α-Ti(HPO4)2·H2O: Experimental and Computational Studies

“…Bimetallic NPs have often shown improved catalytic performances in comparison to their monometallic assemblies because of their long-term stabilities and selectivity features . For example, bimetallic Co–Pt NPs anchored on cellulose nanofibers have shown a rapid and ∼100% conversion of 4-NP to 4-AP in the presence of NaBH 4 . Metal-supported semiconductor materials such as Mg/ZnO, Zn/Ga 2 O 3 , Cu/MgO, and Ir/CeO 2 utilized as heterogeneous catalysts have shown promising results in the reduction of 4-NP in the presence of NaBH 4 .…”
