Preparation of mesoporous ThO nanoparticles: Influence of calcination on morphology and visible-light-driven photocatalytic degradation of indigo carmine and methylene blue.

The present article reports the synthesis of thoria nanoparticles (ThO NPs) via sol-gel process and examines the effect of calcination temperature of ThO on the morphology and photocatalytic degradation of indigo carmine (IC) and methylene blue (MB) under visible-light. As-synthesized white crystals of ThO were subjected to calcination at different temperatures, viz. 700 °C (TH-700), 800 °C (TH-800), and 900 °C (TH-900).

Biosynthesized δ-BiO Nanoparticles from Flower Extract for Photocatalytic Dye Degradation and Molecular Docking.

Bioinspired delta-bismuth oxide nanoparticles (δ-BiO NPs) have been synthesized using a greener reducing agent and surfactant co-precipitation method. The originality of this work is the use of flower extract for the first time for the fabrication of NPs, which were further calcined at 800 °C to obtain δ-BiO NPs. Physicochemical studies such as FTIR spectroscopy and XPS confirmed the formation of BiO NPs, whereas XRD and Raman verified the formation of the cubic delta (δ) phase of BiO NPs.

Biogenic Synthesis of Metal/Metal Oxide Nanostructured Materials.

Nanotechnology is an emerging outlet of nanoscience in which the atoms are encompassed in nanoscale dimensions and become more receptive compared with their distinctive counterparts. Recently, the utilization of synthetic designs and physicochemical approaches has received special attention; nevertheless, the generation of noxious impressions on the eco-system has raised serious concerns of the scientific community worldwide. Presently, environment-friendly green synthesis routes are promising venues for the arrangement of Metal/Metal Oxide (M/MO) nanostructured materials by using plants and their corresponding alliances.

Bioinspired Reduced Graphene Oxide Based Nanohybrids for Photocatalysis and Antibacterial Applications.

Ultra-thin graphene has been receiving significance in the diverse sections of material science, owing to its exceptional physicochemical and thermo-mechanical characteristics. Currently, the fabrication of high-grade graphene in an economical target and green procedures area is a massive concern. Among the diverse techniques, chemical-mediated fabrication is believed to be the finest process since it is simple, scalable, and of low-cost; however, it involves noxious or hazardous chemical reducers for producing functional graphene-based Nanocomposites (NCs).

Mesoporous Octahedron-Shaped Tricobalt Tetroxide Nanoparticles for Photocatalytic Degradation of Toxic Dyes.

The present article reports a facile approach to fabrication of mesoporous octahedron-shaped tricobalt tetroxide nanoparticles (CoO NPs) with a very narrow size distribution for eco-friendly remediation of toxic dyes. CoO NPs were fabricated by a solgel process using cobalt chloride hexahydrate (CoCl·6HO) and monosodium succinate (CHONa) as a chelating/structure-directing agent and sodium dodecyl sulfate as a surfactant. Moreover, the phase structure, elemental composition, and thermal and morphological facets of CoO NPs were investigated using XRD, FT-IR, EDS, Raman, XPS, TGA, SEM, and TEM techniques.
