A new and efficient nanocatalyst was identified, synthesized and introduced and its catalytic activity was investigated in the Suzuki coupling reaction. This nanocatalyst can be synthesized by sulfonating natural asphalt as a high-carbon, cost-effective and accessible substrate using high-concentration sulfuric acid. After being neutralized by NaOH, it was transformed into sodium natural asphalt sulfonate (Na-NAS). Ultimately, the nanocatalyst was synthesized through a displacement reaction of sodium natural asphalt sulfonate with copper chloride. The solid derived (NAS@Cu) was identified using Transmission Electron Microscopy (TEM), Energy Dispersive Spectroscopy (EDS), Scanning Electron Microscopy (SEM), N2 sorption isotherms, Inductively Coupled Plasma (ICP), X-ray Diffraction (XRD), Thermogravimetric Analysis (TGA), Atomic Absorption Spectrometry (AAS) and Fourier-transform Infrared spectroscopy …
