Nano-peanut shell‑OSO3H nanoparticles were simply prepared and characterized by the scanning electron microscopy (SEM), transmission electron microscope (TEM), fourier transform infrared (FT-IR), energy dispersive X-ray spectroscopy (EDX), and thermal analysis techniques (TGA/DTG). The catalytic activity of nano-peanut shell‑OSO3H was studied in the synthesis of biologically important 4H-pyran derivatives. The reaction involves the use of Kojic […]
