Bimetallic Metal-Organic Framework Derived Nanocatalyst for CO2 Fixation through Benzimidazole Formation and Methanation of CO2

In this paper, a bimetallic Metal-Organic Framework (MOF) CoNiBTC was employed as precursor for the fabrication of nanoalloys CoNi@C evenly disseminated in carbon shells. These functional nanomaterials are characterized by powdered X-ray diffraction (PXRD), Fourier Transform Infra-Red spectroscopy (FTIR), surface area porosity analyzer, photoelectron (XPS), Field emission scanning electron microscopy (FESEM), Transmission (TEM), Hydrogen Temperature-Programmed Reduction (H2 TPR), CO2 Desorption (CO2-TPD), and Inductively Coupled Plasma Mass Spectrometry (ICP-MS). This nanocatalyst utilized synthesis benzimidazole from o-phenylenediamine presence H2 good yield 81%. The catalyst also efficient manufacture several substituted benzimidazoles with high yield. Due to existence nanoalloy Co Ni, methanation selectivity (99.7%).
