[email protected] NPs and were synthesized by precipitation method involving three mechanisms: inclusion, occlusion, adsorption. The characterized with the help of UV-Vis spectroscopy, FESEM-EDAX, powder x-ray diffraction, TEM, ESIMS, TG/DSC analysis. morphology hexagonal rectangular, particles in range 7–12 nm. UV–visible spectral measurements showed surface plasmon resonance at 320 nm–340 nm band gap 3.65 eV–3.86 eV. catalytically active CoSNPs called investigated for reduction 4-nitrophenol (4-NP) via hydrogenation using sodium borohydride (NaBH4) as a reducing agent. Both CoS successfully reduced 4-NP to 4- aminophenol (4-AP) short time, catalytic performances are almost unchanged first five cycles. Herein, we report preparation characterizations efficient consisting carbodithioic acid framework support/capping material, along property.
