3D porous network structured cobalt and nickel bead catalysts were easily-greenly fabricated in the presence of chitosan for the catalytic reduction of 4-nitrophenol to 4-aminophenol. Physicochemical properties and morphology were determined using XRD, nitrogen adsorption/desorption, FTIR and SEM /EDS analyses. While XRD pattern and FTIR spectra showed presence of chitosan, peaks related with cobalt and nickel species were not observed. Nitrogen adsorption/desorption isotherms exhibited a behavior indicating of micro-mesoporous structure. The surface area (41.24 m2/g), total pore volume (0.035 cm3/g) and pore diameter (3.59 nm) values of Ni@chitosan catalyst was acquired higher than that of Co@chitosan catalyst. EDS mapping showed that cobalt and nickel homogeneously distributed in the chitosan structure. Co@chitosan exhibited higher catalytic activity. Reaction rate constant values were found as 0.498 and 0.074 min-1 for Co@chitosan and Ni@chitosan, respectively. The catalytic activity of the catalysts was competitive and guide for 4-nitrophenol reduction applications.
