“…Therefore, it is possible to build optical sensors with adjustable properties [13,14]. Various methods for the preparation of nanocomposites (N/C) are known in literature such as ultrasonic method, microbial method, microwave-assisted heating, layer by layer, ultraviolet irradiation, solvothermal method, electrodeposition [15][16][17]. One important feature of our approach is the stabilizing possibility of NP at the growing time.…”

“…12 CuS is an important p-type semiconductor with 2.2 eV direct band gap, which belongs to the wurtzite structure with vacancies within the lattice, providing its application in optoelectronic devices. 13,14 Due to its technological importance, the fabrication of CuS remains a main focus of interest to adopt new synthetic routes for obtaining phase pure material via economically and technically viable procedures. Numerous methods have been developed for the chemical synthesis of CuS nanostructures including hydrothermal technique, non-template free chemical route, sol-gel, chemical conversion, sonochemical, photo chemical methods, [13][14][15][16] etc.…”

“…[ 3,4 ] The band gap values indicate the gaps determined for all the semiconductors that exist in the visible‐light region; hence, they can be applied in photocatalysis. [ 5 ] Zinc containing layered double hydroxides [ 6–8 ] oxides [ 9–12 ] sulfides [ 13–15 ] and other semiconductors [ 16 ] are very effective photocatalysts with unique optical properties. It is important for electrons to move from the valence band (VB) to the conduction band (CB) under less energy irradiation.…”

In this work, zinc-aluminum layered double hydroxides were synthesized with and without the presence of polyvinyl alcohol by co-formation and co-precipitation methods, respectively. The photocatalytic activity of the obtained nanocomposites was studied and a comparative analysis was performed. The mechanism of photocatalytic decomposition of Ponceau 4R (P4R) on the nanocomposites has been explained in detail by relating it to the compositional and structural properties of the nanocomposite. The structural and optical properties of nanocomposites are characterized by XRD, UV-vis, PL, and SEM in a pure state, dye loaded and after photodegradation. The bandgap of nanocomposites (E g = 3,23 eV) was reduced after sorption (E g = 3,1 eV) and photocatalytic degradation (E g = 2,87 eV) of P4R. This result is in good agreement with basal spacing determined by XRD. To study the sunlight degradation of P4R at different initial concentrations (8,12,16,20,30,40, 50 mg L À1 ), firstly sorption was developed with Langmuir and other isothermal models. The Langmuir constant value (K L = 0,102) of ZnAl-LDH/PVA is close to the Langmuir-Hinshelwood constant (K L-H = 0,094) obtained from the kinetics of the photodegradation in sunlight. The photocatalytic degradation of P4R onto the obtained nanocomposites follows the Langmuir-Hinshelwood kinetic model.
