We report the synthesis of bamboo stem porous activated carbon/chitosan/zinc oxide (BSPAC/CS/ZnO) ternary composite using co-precipitation method. Subsequently, the synthesized BSPAC/CS/ZnO ternary nanocomposite was confirmed by FT-IR, powder XRD, Raman, FE-SEM, EDAX with elemental mapping, HR-TEM, UV-vis DRS, TGA, XPS and BET surface analysis. The distinctive surface area of composite material has been 55.354 m
