Inexpensive, stable, selective, and recyclable nanocatalysts, waste regeneration, utilization of safe available solvents are interest important factors in laboratory science industrial applications green chemistry. Therefore, herein, biochar nanoparticles (BNPs) were synthesized through chicken manure pyrolysis as a novel method for recycling. Then, order to improve their recyclability, the obtained BNPs magnetized using magnetic nickel nanoparticles. surface (BMNPs) was modified by (3-chloropropyl)trimethoxysilane (3-CPTMS) further neodymium Schiff-base complex immobilized on BMNPs, denoted Nd-Schiff-base@BMNPs. The supported used practical, biocompatible, commercial, reusable heterogeneous nanocatalyst. support this nanocatalyst formed from manure; therefore, it is cheap, economically viable, also compatible with principles Nd-Schiff-base@BMNPs acts selectively organic reactions can easily be recovered an external magnet reused, which This characterized wavelength-dispersive X-ray spectroscopy (WDX), scanning electron microscopy (SEM), energy-dispersive (EDS), thermogravimetric analysis (TGA), Fourier transform infrared (FT-IR), inductively coupled plasma (ICP), N
