Двумерные наноструктуры (2D) привлекли значительный интерес и большое внимание в современной науке, благодаря своей большой площади поверхности, электронным свойствам, характеристикам накопления энергии и каталитической активности. Слоистые двойные гидроксиды (СДГ) относятся к двумерным наноструктурам и обладают большой площадью поверхности, очень важными физико-химическими свойствами и биологической активностью. Однако всегда существовал большой интерес к их легированию для усиления и улучшения этих свойств, особенно фотокаталитической активностью. В данной работе были синтезированы СДГ на основе ZnAl и проведено их легирование активными (Ca, Sr), переходными (Co, Cu, Cd, Ni, Pb, Fe), благородными (Ag) и редкоземельными элементами (La) осуществлялись методом пропитки. Также было изучено удаление катионных и анионных красителей из водных растворов путем адсорбции и фотодеградации на свежесинтезированном и легированном нанокомпозите ZnAl-СДГ/ПВС. Полученные результаты сопоставлены со структурой и физикохимическими свойствами нанокомпозитов.

Due to their high surface area, electronic properties, energy storage performance and catalytic activity, two-dimensional (2D) nanostructures have attracted significant interest and great attention in developing science. Layered double hydroxides (LDHs) belong to 2D nanostructures and have a high surface area, very important physicochemical properties, and biological activity. However, there has always been great interest in their doping to enhance and improve these unique properties, especially photocatalytic activity. In this work, ZnAl-based LDHs were synthesized and their doping with active- (Ca, Sr), transition- (Co, Cu, Cd, Ni, Pb, Fe), noble- (Ag) and rare earth- (La) metals were carried out by impregnation method. The removal of cationic and anionic dyes from aqueous solutions by adsorption and photodegradation on as-synthesized and doped ZnAl-LDH/PVA nanocomposite was also studied. The obtained results were correlated with the structure and physicochemical properties of the nanocomposites.
