“…The photodegradation percentage of MB is 82.88 and 85.71% at 0.2 g/L of α-Fe 2 O 3 and Coα-Fe 2 O 3 respectively. The same phenomenon was observed by other researchers [20,22,40]. When the catalyst dosage is optimised (0.2 g/L), more active sites become available on the catalyst's surface.…”

“…Furthermore, unlike α-Fe 2 O 3 , Co-α-Fe 2 O 3 has a Co 2þ impurity energy level that traps electrons, lowering the electron-hole pair recombination rate [40]. This is the main explanation for the slight improvement in photocatalytic activity of Co-α-Fe 2 O 3 compared to non-doped α-Fe 2 O 3 [25].…”

“…Owing to outstanding photocatalytic properties, semiconductor photocatalysts are highly likely considered as competitive candidate on degradation organic contaminates in water and wastewater purification processes 32 – 37 . Moreover, several studies have been reported photodegradation of azo days using various nanomaterials such as CeO 2 nanostructures 38 , CeO 2 /CuO nanocomposites 39 , Fe–doped CeO 2 films 40 , CeO 2 /Fe 2 O 3 composite 41 , phthalocyanine-TiO 2 nanocomposite 42 , In/ZnO nanocomposite 43 and V 2 O 5 -CeO 2 nanocatalyst 44 . As per economic and environmental prospective, our findings show greater efficiency rather than chemically-produced CeO 2 NPs toward same pollutant under UV irradiation 45 .…”

This contribution presents the biosynthesis, physiochemical properties, toxicity and photocatalytic activity of biogenic CeO2 NPs using, for the first time, marine oyster extract as an effective and rich source of bioreducing and capping/stabilizing agents in a one-pot recipe. CeO2 NPs formation was initially confirmed through the color change from light green to pale yellow and subsequently, their corresponding absorption peak was spectroscopically determined at 310 nm with an optical band-gap of 4.67 eV using the DR-UV technique. Further, XRD and Raman analyses indicated that nanoceria possessed face-centered cubic arrangements without any impurities, having an average crystallite size of 10 nm. TEM and SEM results revealed that biogenic CeO2 NPs was approximately spherical in shape with a median particle size of 15 ± 1 nm. The presence of various bioorganic substances on the surface of nanoparticles was deduced by FTIR and TGA results. It is found that marine-based nanoceria shows no cytotoxic effect on the normal cell, thus indicating their enhanced biocompatibility and biosafety to living organisms. Environmentally, due to energy band gap, visible light-activated CeO2 nanocatalyst revealed superior photocatalytic performance on degradation of methylene blue pollutant with removal rate of 99%. Owing to the simplicity, cost-effectiveness, and environmentally friendly nature, this novel marine biosynthetic route paves the way for prospective applications of nanoparticles in various areas.

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-
