We investigated the fabrication of Ca/Al layered double hydroxide (LDHs) via a one-step hydrothermal approach with slow hydrolysis of urea at a low temperature without further annealing required. The as-synthesized Ca/Al LDHs nanostructures obtained were defined using Fourier transforms infrared spectroscopy (FT-IR), thermogravimetric analysis (TGA), powder X-ray diffraction (XRD), and scanning electron microscopy (SEM). The results demonstrated that Ca/Al LDHs exhibit excellent adsorption performance on Congo red anionic dyes in aqueous solution. The adsorption capacity of the Ca/Al LDHs toward Congo red was found to be 59.41 mg/g.

A facile one-step solvothermal route was developed to synthesize NiO nanoflowers (200-300 nm in diameter) with the introduction of poly(vinyl-pyrrolidone)/stearic acid (PVP/SA) mixture. The product was characterized by X-ray powder diffraction (XRD), field-emission scanning electron microscopes (FESEM), Fourier transform infrared spectrometry (FT-IR), Thermal gravimetric analyze (TGA), and Brunauer-Emmett-Teller (BET). The mesoporous NiO nanoflowers showed an excellent adsorption capacity for organic pollutants (Congo red) from waste water (about 56 mg Congo red per g NiO).
