A new nanobiocomposite (NBC) based on lignocellulosic waste peanut shell PS/ZnO was prepared via in situ hydrothermal synthesis and characterized by FT-IR analysis, Scanning Electron Microscopy (SEM), Energy-Dispersive X-ray Spectroscopy (EDX) and Energy-Dispersive X-ray Spectroscopy. Lignocellulosic waste (LCW) peanut shell is composed of cellulose, hemicellulose, and lignin. PS/ZnO has been successfully used in a sustainable catalytic method for the synthesis of pyrimido [1,2-b] benzazole derivatives through a one pot the three-component reaction between a source of amine such as 2-aminobenzimidazoles, 2-aminobenzothiazoles or guanidine, an aromatic aldehyde and C-H acidic compounds derivatives in water under microwave irradiation in a very short time and good yields.
