The research was carried out the preparation of Ni-Al layered double hydroxide (LDH) with magnetite biochar (MBC) material to form a Ni-Al/magnetite biochar composite. XRD (X-Ray Diffraction) characterisation of Ni-Al/magnetite biochar interaction and the formation of bonds resulting in typical peaks of layered double hydroxide diffraction at 2θ = 11.38° and 61.20° and magnetite biochar at 2…
