Copper aluminate spinel by soft chemical routes
Source abstract
Abstract
Abstract Copper aluminate spinel (CuAl 2 O 4 ) was obtained by two different chemical routes: the precursor method and the solution combustion method involving glycine-nitrates. The polynuclear complex compounds: (NH 4 ) 2 [CuAl 2 (C 4 O 6 H 4 ) 3 (OH) 4 ]·2H 2 O ( I ), (NH 4 )[CuAl 2 (C 6 O 7 H 11 ) 3 (OH) 6 ]·2H 2 O ( II ) and [CuAl 2 (NH 2 CH 2 COOH) 4.5 ]·(NO 3 ) 8 ·4H 2 O ( III ) were characterized by elemental chemical analysis, infrared spectroscopy (IR), ultraviolet–visible spectroscopy (UV–vis) and thermal analysis. The final oxide powders were characterized by X-ray diffraction (XRD), scanning electron microscopy (SEM), IR, Raman spectroscopy (RS), UV–vis and photoluminescence (PL) spectroscopy. X-ray diffraction patterns indicated the formation of the cubic phase CuAl 2 O 4 with good crystallinity. The crystallite size ranged from 18.70 to 19.50 nm. Electron microscopy revealed the morphology corresponding to the complete crystallization into CuAl 2 O 4 . The band gap values ranged between 1.97 and 2.03 eV. The photocatalytic degradation of methyl orange (MO) was investigated using copper aluminate as catalyst.
