A Simple but Efficient Catalytic Approach for the Degradation of Pollutants in Aqueous Media through <i>Cicer arietinum</i> Supported Ni Nanoparticles

Abstract Plant based materials are considered to have broad applications in the remediation of toxic materials. In this report, we present an environmental friendly and economic Cicer arietinum , named as (CP) supported for the synthesis of Ni nanoparticles (NPs) designated as Ni@CP. The in situ Ni@CP NPs were obtained using aqueous medium in the presence of sodium borohydride (NaBH 4 ) as a reducing agent. The prepared catalysts were applied for the hydrogenation/degradation of p -nitrophenol (PNP), o -nitrophenol (ONP), and 2,4-dinitrophenol (DNP), as well as congo red (CR), methyl orange (MO), methylene blue (MB) and rhodamine B (RB) dyes. The amount of total metal ions adsorbed onto the CP was evaluated by flame atomic absorption spectroscopy. The Ni@CP catalyst was characterized through PXRD, FTIR, FESEM and EDX analyses.
