Synthesis of Ni2+–Al3+–LDHs with flower-like morphology assembled from an ultrathin platelets structure: Phenomenon of enhanced photocatalytic performance

This study was initiated to explore a method for producing higher photocatalytic performance in layered double hydroxides (LDHs) through the preparation of ultrathin nanosheets, which would generate surface area (SA). Herein, is detailed fabricating Ni2+-Al3+-LDHs with flower-like morphology assembled from an nanosheet (Ni2+-Al3+-LDHs-U) employing low temperature-reflux together surfactant. The resulting products’ structures, morphologies, porous properties, and bandgaps were investigated using series characterization techniques, confirmed formation Ni2+-Al3+-LDHs-U structure (4–8 nm) large SA (151 m2/g), nearly three times greater than comprising thick (50 nm, Ni2+-Al3+-LDHs-T). In addition, these new materials 5.11 electron volts lower Ni2+-Al3+-LDHs-T material (5.26 eV). These exhibited greatly enhanced light response that utterly decomposed methyl orange Rhodamine B water, represented far better photodegradation under similar conditions compared thicker Ni2+-Fe3+-LDHs-T. increased photoreaction efficiency explained by catalytically active sites experimental product.
