“…MoO 3 NPs and their composites have been used as gas sensors [14] and as electrode materials for energy conversion and storage [15,16]. They have been effectively used in various catalytic reactions such as alcohol oxidation [17], epoxide ring-opening [18], ethanol oxidation, oxygen reduction [19], n-dodecane oxidation [20], sulfide to sulfate oxidation [21], and olefin epoxidation [22]. Moreover, MoO 3 NPs are multifunctional due to their unique layered structures and the wide range of oxidation states of different polymorphs.…”

Molybdenum trioxide nanoparticles (MoO3 NPs) are recognized for their applications in novel multifunctional devices. Here, a biogenic, environmentally friendly method using Lepidagathis cristata leaf extract was employed to synthesize MoO3 NPs. The as-obtained MoO3 NPs exhibited a predominant (0 k0) orientation, representing an α-MoO3 structure. The absorption band at 984 cm-1 observed in the Fourier-transform infrared spectrum corresponded to the terminal Mo = O bond, thereby confirming that the prepared MoO3 NPs were in the orthorhombic phase. Scanning and transmission electron microscopy data revealed that the MoO3 NPs were well crystallized and uniformly distributed with grain sizes in the 70-100 nm range. The biogenic MoO3 NPs demonstrated an excellent zone of inhibition against the selected Gram -ve and Gram +ve bacterial strains, thus providing an alternative to standard antibacterial agents. During electrochemical experiments conducted in a 1 M aqueous Na2SO4 solution, cyclic voltammetry (CV) curves of the MoO3 NPs showed a pseudocapacitive nature, with a high discharge specific capacitance of 294 F/g and good cyclability. These results suggest the feasibility of the proposed biogenic, environmentally friendly method for preparing MoO3 NPs for application in multifunctional devices.

1D Coordination Polymer (CP) of [Cu I (1,3-NCS)(DAFO)]n (CP1) (DAFO = 4,5-Diaza uoren-9-one) was synthesized using a branched tube method in ethanol and compared with previously synthesized CP2. Although the synthesis methods and parameters for CPs were di erent, both of them were formed in a similar crystal system (orthorhombic) and space group (P mn2 1 ) based on their X-ray crystallography data. Optical properties and structure of CP1 were further investigated in detail. Variation of the crystallography temperature causes slight di erences in the bond lengths and angles of the geometry center. Hirshfeld surface analyses show the signi cant contribution of H{C...H (18.9%) for CP1 and H{C...H (19.9%) for CP2. The most obvious distinctions between the CP interactions were C{N (8.4%) and (3.3%), Cu{S (4.8%) and (0.0%), and Cu{N (3.3%) and (11.4%) for CP1 and CP2, respectively. Non-Covalent Interaction-Reduced Density Gradient (NCI-RDG) analysis was conducted to broaden our understanding of the structure-directing interactions in these complexes. CP1 experienced signi cant inter-and intramolecular interactions according to Hirshfeld surface and NCI-RDG analyses. Solventfree decomposition of CP1 crystals at 750 C led to the synthesis of copper oxide (CuO) nanoparticles with a particle size of 12 nm.

“…Copper molybdate is one of the significant inorganic transition metal oxides that possess high potential application in different fields such as catalysis, laser hosts, optical fibers, microwave, humidity and gas sensors applications. Recently, numerous investigations have been accounted for the synthesis of copper molybdate like precipitation [10], hydrothermal [11], flame spray strategy [12] sonochemical [13], micro-emulsion [14], etc. In many cases, these techniques more often require post high temperature calcination, time consuming, larger solution usage, complicated steps requirements, etc.…”

Spherical copper molybdate (Cu3Mo2O9 ) nanoparticles (NPs) have been prepared via the microwave combustion technique. The structural, morphological and elemental characterizations have been investigated by PXRD, SEM and EDS studies. It was found that the as-prepared sample possesses nanoplate morphology and particles size was found to be around 18 nm. The as-prepared sample was inspected in the disintegration of Methylene Blue (MB) dye envisioned using UV-Visible spectroscopy. It was found that the prepared nanocatalyst could serve as an active photocatalyst for MB under direct sun light.
