Auto-combustion Fabrication and Optical Properties of Zinc Oxide Nanoparticles for Degradation of Reactive Red 195 and Methyl Orange Dyes

Abstract

We are pleased to submit the attached original research article entitled "Auto-combustion fabrication and optical properties of zinc oxide nanoparticles for degradation of reactive red 195 and methyl orange dyes" for consideration for publication as a research article Journal of Inorganic and Organometallic Polymers and Materials.In this manuscript, zinc oxide nanoparticles were synthesized using an auto-combustion technique with fuels (tartaric acid and citric acid) according to the rule of the combustion method. the obtained zinc oxide nanoparticles were studied using various tools such XRD, DRS, TEM and FTIR.The results of XRD confirmed that the formation of the hexagonal structure of the synthesized zinc oxide after calcination at 500 o C. The extracted data from XRD and TEM techniques showed that the crystallite size of the fabricated zinc oxide nanoparticles determined to be 24-39 nm. The direct band gap, lattice parameters, unit cell volume (V), the dislocation density (D) and the Zn-O bond length (L) of the synthesized zinc oxide were determined. The values of the lattice parameters (a and c), the ratio (c/a), unit cell volume (V) and Zn-O bond length (L) were determined and found in the range of 3.2333-

Microbial Mediated Synthesis of Zinc Oxide Nanoparticles, Characterization and Multifaceted Applications

“…Moreover, the synthesized ZnONPs were used as nanocatalyst for photodegradation of reactive red 195 and methyl orange as anionic dyes utilizing UV light irradiation. The degradation of reactive red 195 dye was 91-94% after 70 min over the synthesized zinc oxide and the values of degradation increased to be 99-99.8% in 50 min with H 2 O 2 under UV light irradiation [171].Therefore, these findings confirmed an effective approach to utilize ZnONPs as an efficient photocatalyst agent.…”

Auto-combustion synthesis and characterization of zirconium oxide nanoparticles for removal of crystal violet dye from aqueous solution

“…Thermodynamic parameters such as enthalpy (ΔH°) and entropy (ΔS°) in addition to Gibb's free energy (ΔG °) can be calculated for the removal of (CV) by ZrO 2 nano adsorbents (ZU sample) from the following Eq. (11,12) [11].…”

“…There were many methods used for water treatment such as microbial decomposition, oxidation, coagulation, reverse osmosis, ion exchange, photo-catalytic degradation, electrodialysis, electrolysis as well as adsorption [5,6]. Low cost, nonexistence of harmful residues and ease of operation distinguished adsorption method among various water treatment ones [7][8][9][10][11][12][13]. ZrO 2 has attracted considerable attention due to its usage in industrial and medical applications such as fire-and heat-resistant material, wide band-gap semiconductor material, catalyst, solid oxide fuel cell , oxygen sensors, dental and body implants and ceramic biomaterial owing to its remarkable physical properties, such as high melting point, high strength, good toughness, corrosion resistance and low thermal conductivity [14][15][16][17].…”
