Abstract

An eco-friendly approach is described for the generation of Ni nanoparticles on a magnetized cellulose biopolymer wherein the adorned biopolymer mimics a core–shell type nanocomposite (Fe3O4@CNF@Ni) is realized via sonication. The physicochemical and morphological specifications of the ensued nanocomposite were characterized using various advanced techniques like FT-IR, FESEM, TEM, EDX, VSM, BET-BJH, DLS, XRD, TGA, XPS and ICP-OES. The catalytic performance of the Fe3O4@CNF@Ni was evaluated in the ultrasound-assisted classical Hiyama and Suzuki–Miyaura cross-coupling reactions for the synthesis of a variety of biaryl derivatives; superior performance was discerned for both the protocols where sonication played a vital role relative to conventional heating for expeditious reaction, easier work-up and higher yields. Hot filtration and Hg toxication tests for the nanocomposite, Fe3O4@CNF@Ni revealed higher stability, and low metal leaching. Its heterogeneous nature as the magnetically retrievable catalyst could be ascertained by reuse in up to seven successive cycles without significant loss of efficacy.
