(A) SEM images of boehmite (γ-AlOOH) produced from commercial aluminium chloride (AC120) and aluminium foil waste (ACFL120) along with the γ-Al2O3 produced from commercial aluminium chloride (AC550) and aluminium foil waste (ACFL550). (B) (a) TEM overview image of the TEM-BF, (b) the acquired area of SAED pattern of the un-purified ACFL550 (γ-Al2O3 prepared from Al foil) with SAED pattern.
