Green sol–gel auto combustion synthesis and characterization of double perovskite Tb₂ZnMnO₆ nanoparticles and a brief study of photocatalytic activity

Abstract

In this work, new double perovskite Tb2ZnMnO6 nanoparticles were successfully synthesized by a sol–gel auto combustion method.

Insight into nanocrystal synthesis: from precursor decomposition to combustion

“…Besides, taking the optimum maltose fuel and two different fuel/terbium ratios (1 : 2 and 3 : 2), the fuel-lean ratio (1 : 2) showed a good surface area and morphology. 79…”

Photocatalytic and antibacterial activities of Tl–Hg–I nanocomposites: sonochemical synthesis and characterization

“…Then the samples were analyzed by UV-vis spectrophotometer. The efficiency of Tl 4 HgI 6 /HgI 2 nanocomposite in photocatalytic process in decolorization is calculated as follows: 20 % decolorization= (( A t − A 0 )/ A 0 ) × 100; where A 0 and A t is the amount of dye absorption before and after exposure to light.…”

An ultra-low-cost and adjustable in-house electrospinning machine to produce PVA nanofiber

“…Apart from those studies, according to [19] , Pd/rGO nanocomposite as an efficient catalyst was synthesized by the sol immobilization method of Pd nanoparticle deposition on rGO. Indeed, a new double perovskite Tb 2 ZnMnO 6 nanoparticles were successfully synthesized by a sol–gel auto combustion method to increase the photocatalytic activity [20] . Another alternative in preparing the nanostructure was successfully reported by [21] , [22] respectively.…”
