Advanced Metal Oxide Nanostructures for Environmental Remediation: Synthesis and characterization of PbO, MgO, TiO₂ and Fe₂O₃ | Chapter 5 | Chemical and Materials Sciences: Developments and Innovations Vol. 8

Aims: This study discusses the synthesis and characterization of metal oxide nanomaterials for environmental remediation applications, with emphasis on their photocatalytic properties.

Methodology: Two kinds of metal oxides, PbO and MgO, were prepared for the degradation application of textile dye methylene blue. In parallel, a porous thin film with heterojunction of TiO₂ modified by polyethylene glycol (PEG) prepared by several molecular weights from 300 to 20.000 the best porous sample was covered by Fe₂O₃ by electrodeposition technique.

PbO and MgO oxides were synthesized by coprecipitation, while TiO₂-PEG/Fe₂O₃ heterojunction was prepared by Sol-Gel, spin coating and electrodeposition method. Structural characterization was performed by X-ray diffraction (XRD), Raman spectroscopy, and morphological analysis by atomic force microscopy (AFM) also with transmission electron microscopy (TEM). Photocatalytic performances were evaluated via the degradation of methylene blue dye.

Results: PbO and MgO oxides, as well as TiO₂-PEG/Fe₂O₃ heterojunction, demonstrated significant efficiency in the degradation of methylene blue dye, confirming their potential for environmental remediation. The results show that these nanomaterials can be effective agents for the photodegradation of organic contaminants.

Conclusion: Metal oxide nanomaterials have great potential for environmental remediation applications.

Synthesis and Evaluation of Imidazolium Based Ionic liquIds as Corrosion Inhibitor for Mild Steel in Hydrochloric Acid Medium: Electrochemical, Thermodynamic and Theoretical Studies| Chapter 4 | Research Aspects in Chemical and Materials Sciences Vol. 3

 Iimidazolium based ionic fluids (ILs, for example, 3-hexadecyl-1-methyl-1H-imidazol-3-ium bromide [C16M1Im] [Br] and 3-hexadecyl-1,2-dimethyl-1H-imidazol-3-ium bromide [C16M2Im] [Br] were combined and assessed for erosion obstruction on gentle steel in 1M HCl arrangement by weight reduction and electrochemical strategies. The outcomes uncovered that the restraint proficiency, upgraded with an ascent in the centralization of inhibitor. Furthermore, [C16M2Im] [Br] showed more noteworthy inhibitory viability than [C16M1Im] [Br] because of the expansion of more alkyl substituents. As per a polarization examination, the used inhibitors display blended type conduct however basically make anodic inhibitory impacts. The Langmuir adsorption isotherm is trailed by the inhibitors adsorbed on the gentle steel surface. Nuclear power microscopy (AFM) and filtering electron microscopy (SEM) with EDAX examination were utilized to break down the surface geography. The improvement of the Fe-inhibitor complex on the outer layer of gentle steel has been checked by UV-apparent spectroscopy. Quantum substance boundaries determined for [C16M1Im] [Br] and [C16M2Im] [Br] support the outcomes acquired from trial techniques.

Immobilization of BSA onto Graphene Oxide Synthesized from Hydrogenated Diamond-like Carbon| Chapter 1 | Progress in Chemical Science Research Vol.3

 Over the past few years, biomolecules, and Graphene oxide (GO) material studies have increased. The numerous processes for producing graphene oxide are being improved in an effort to offer safer and more efficient substitutes. Even though the Hummers method is one of the oldest, it continues to be one of the most effective ways to make graphene oxide from graphite powder or flake. In this chapter, GO has been synthesized from Hydrogenated diamond-like carbon (HDLC) which is tunable and an atomically smooth surface that can be deposited on a high-surface-area (100) wafer plate. The HDLC films were heated at a fixed temperature of 9000C for 30 min in a high vacuum of 1 × 10-6 torr and oxygenated at room temperature. This annealed HDLC (A-HDLC) was oxidized and described sequentially. FTIR confirms functional groups and Raman measurements confirm the G and D peak by Oxidation of A-HDLC. The surface morphology of BSA immobilized go, Oxidized Graphene, and A-HDLC, were studied by atomic force microscopy (AFM).
