“…However, a lower number of nucleation sites were thermodynamically distributed on the centers of the facets of the cube, which might have resulted in the formation of hollow structures. In the nucleation process for CeVO 4 , this can be traced back to the smaller structural units, namely, the VO 4 and CeO 8 groups [ 23 ]. In order to explore their effects, the molar ratios of the precursors were modulated.…”

Ternary orthovanadate compounds have received increasing attention due to their broad light absorption and diverse crystal structure. However, their multi-assembled crystal morphologies are limited mainly due to their initially polyatomic VO4 groups. In this study, multi-prismatic hollow cubic CeVO4 microstructures were fabricated by a one-step solvothermal method without any organic agents. The increase in wall thickness is in accordance with the radial direction of the quadrangular prism. Moreover, the overdose of the V precursor is favorable for the formation of hollow micro-cubic CeVO4, and the wall thickness changes from 200 to 700 nm. Furthermore, these CeVO4 microstructures were applied to photocatalytic CO2 reduction with a maximum CO generation rate of up to 78.12 μmol g−1 h−1 under visible light irradiation, which was several times higher than that of the other samples. This superior photocatalytic activity might be attributed to its good crystallinity and unique exposed interior structure. This study provides guidelines for the multi-assembled structure fabrication of ternary compounds and expands upon the exploration of the spatial structure of multivariate compounds.

“…In some cases, the metal resists proteins exhibited the reduction and capping of NPs to overcome the aggregation of NPs and enhance their stability for a prolonged incubation period. Researchers have shown the bioreduction and capping of potassium permanganate (KMnO 4 ) into manganese dioxide (MnO 2 ) NPs using Saccharomyces cerevisiae cellular machinery [ 44 ]. Subsequently, Silver NPs (AgNPs) were synthesized from cell-free extracts of different microbial strains, i.e., Bacillus paralicheniformis , Bacillus pumilus and Sphingomonas paucimobilis .…”

Water scarcity due to contamination of water resources with different inorganic and organic contaminants is one of the foremost global concerns. It is due to rapid industrialization, fast urbanization, and the low efficiency of traditional wastewater treatment strategies. Conventional water treatment strategies, including chemical precipitation, membrane filtration, coagulation, ion exchange, solvent extraction, adsorption, and photolysis, are based on adopting various nanomaterials (NMs) with a high surface area, including carbon NMs, polymers, metals-based, and metal oxides. However, significant bottlenecks are toxicity, cost, secondary contamination, size and space constraints, energy efficiency, prolonged time consumption, output efficiency, and scalability. On the contrary, green NMs fabricated using microorganisms emerge as cost-effective, eco-friendly, sustainable, safe, and efficient substitutes for these traditional strategies. This review summarizes the state-of-the-art microbial-assisted green NMs and strategies including microbial cells, magnetotactic bacteria (MTB), bio-augmentation and integrated bioreactors for removing an extensive range of water contaminants addressing the challenges associated with traditional strategies. Furthermore, a comparative analysis of the efficacies of microbe-assisted green NM-based water remediation strategy with the traditional practices in light of crucial factors like reusability, regeneration, removal efficiency, and adsorption capacity has been presented. The associated challenges, their alternate solutions, and the cutting-edge prospects of microbial-assisted green nanobiotechnology with the integration of advanced tools including internet-of-nano-things, cloud computing, and artificial intelligence have been discussed. This review opens a new window to assist future research dedicated to sustainable and green nanobiotechnology-based strategies for environmental remediation applications.

“… 15 Lakshmana Naik and Bala Narsaiah reported that Zn 2 V 2 O 7 can be synthesized by employing a hydrothermal method on the graphene oxide scaffolds. 16 The literature 17 also reports the synthesis of CeVO 4 nanoparticles by using a variety of techniques, such as ultrasonic, hydrothermal, sol–gel, coprecipitation, microwave irradiation, solvothermal, and sonochemical methods. Although the majority of these methods can produce CeVO 4 nanoparticles with precise sizes and shapes, the hydrothermally produced Co 3 V 2 O 8 thin nanoplates were reported to work well as cathode materials for LiBs.…”

This study reports the synthesis of ferric vanadate (FeVO4) via a facile hydrothermal method, focusing on demonstrating its exceptional electrochemical (EC) properties on detecting low-density ascorbic acid (AA). The phase purity, crystallinity, structure, morphology, and chemical compositional properties were characterized by employing X-ray diffraction, energy-dispersive X-ray spectroscopy, scanning electron microscopy, Raman spectroscopy, and X-ray photoelectron spectroscopy techniques. EC impedance spectroscopy and cyclic voltammetry techniques were also adopted in order to assess the EC response of a FeVO4-modified glassy carbon electrode for sensing AA at room temperature. The AA concentration range adopted in this experiment is 0.1–0.3 mM at a working electric potential of −0.13 V. The result showed functional excellence of this material for the EC determination of AA with good stability and reproducibility, promising its potentiality in connection with relevant sensing applications.
