Sonochemistry fabrication of Er2Sn2O7 nanoparticles with advanced photocatalytic performance of their carbonic nanocomposites

Abstract

The insufficiency of clean water sources has become a perilous tension for the future of the world that one of the eco-friendly and cost-effective solutions is the photocatalytic process for removal of artificial dyes and poisonous organic impurities. In the current research, a simple sonochemistry process was accomplished to gain Er 2 Sn 2 O 7 (ESO) nanoparticles with progressive photo-catalytic proficiency. Various surfactants of cationic Cetyl Trimethyl Ammonium Bromide (CTAB), anionic Sodium dodecyl sulfate (SDS) and polymeric polyethylene glycol 6000 (PEG 6000) were utilized to the creation of pure Er 2 Sn 2 O 7 nanoparticles. The figure and dimension of products were studied by various characterization procedures of spectroscopic and microscopic. The photo-degradation performances of the pure Er 2 Sn 2 O 7 nanoparticles prepared in different conditions were tested to remove of diverse synthetic dyes. Carbon-based nanocomposites of graphitic carbon nitrides (g-C 3 N 4 ), graphene quantum dots (GQDs) and graphene oxide (GO) present enhanced photocatalytic activities. The outcome of the catalyst size, type of dye, kind of carbon structure and scavenger kind was labeled on modifying ability of Er–Sn–O nano-catalyst task. Optimized Er 2 Sn 2 O 7 /g-C 3 N 4 nanocomposites have an efficiency of 93.9% for degradation of acid red dye that OH radicals support photo-degradation of contamination. • Synthesis of Er 2 Sn 2 O 7 nanoparticles via rapid ultrasonic technique. • Investigation of diverse synthesis circumstances on dimension properties of nanostructures. • Consideration of photo-degradation efficiency of Er–Sn–O nanostructures in different experimental conditions. • Investigation of photocatalytic mechanism of Er 2 Sn 2 O 7 /g-C 3 N 4 nanocomposites and kinetic study.
