摘要：

Highly efficient and cost-effective NiO-based carbon nanocomposite (NiO/CNP) was prepared for the transfer hydrogenation of aromatic aldehydes and reduction of nitrophenols. Uniform dispersion of NiO nanoparticles, surface area of NiO/CNP (67 m(2) g(-1)), chemical state and content of Ni in NiO/CNP (+2, 5.1 wt%) were confirmed. High rate constant (k(app)) values of 4.2 x 10(-2) s(-1) and 3.06 x 10(-2) s(-1) were calculated for the NiO/CNP-catalyzed reduction of nitrophenols. The NiO/CNP demonstrated an excellent catalytic activity towards the transfer hydrogenation reactions under very mild reaction conditions. Chemoselectivity, heterogeneity, stability, reusability and scale reaction of the NiO/CNP system were tested. (C) 2017 The Korean Society of Industrial and Engineering Chemistry.
