Novel bilayer 2D VO as a potential catalyst for fast photodegradation of organic dyes.

Two-dimensional (2D) materials have recently drawn interest in various applications due to their superior electronic properties, high specific surface area, and surface activity. However, studies on the catalytic properties of the 2D counterpart of VO are scarce. In the present study, the catalytic properties of 2D VO vis-à-vis bulk VO for the degradation of methylene blue dye are discussed for the first time.

Electronic and Vibrational Decoupling in Chemically Exfoliated Bilayer Thin Two-Dimensional VO.

The synthesis of high-quality two-dimensional (2D) transition metal oxides is challenging compared to 2D transition metal dichalcogenides as a result of the exotic surface changes that can appear during formation. Herein, we report the synthesis of bilayer 2D VO nanosheets with a thickness of ∼1 nm using the chemical exfoliation method and a comprehensive study on the vibrational and optical properties of bilayer 2D VO. We report, for the first time, a thickness-dependent blue shift of 1.

Investigation on CH sensing characteristics of hierarchical VO nanoflowers operated at relatively low temperature using chemiresistive approach.

Methane (CH) gas, the second most potent greenhouse gas share a substantial role in contributing to the global warming and it is a necessary pre-requisite to detect the release of CH into the environment at its early stage to combat climate change. In that front, this work is focussed to develop an effective CH gas sensor using vanadium pentoxide (VO) thin films that works at an operating temperature of ∼100 °C. To understand the effect of sputtering power towards the structural characteristics of VO films, X-ray diffraction (XRD) and high-resolution transmission electron microscopy (HR-TEM) analysis were performed from which the orthorhombic polycrystalline structure of VO thin films was confirmed with varied texture co-efficient.

N'-[(E)-5-Bromo-2-hy-droxy-3-meth-oxy-benzyl-idene]-4-meth-oxy-benzohydrazide monohydrate.

In the title compound, C(16)H(15)BrN(2)O(4)·H(2)O, the hydrazide mol-ecule is nearly planar, with a largest deviation from the mean plane through the non-H atoms of 0.106 (4) Å and a dihedral angle between the benzene rings of 1.98 (16)°.

N'-[(E)-4-Benz-yloxy-2-hy-droxy-benzyl-idene]benzohydrazide.

The title compound, C(21)H(18)N(2)O(3), exists in the E conformation with respect to the azomethane C=N double bond. The central benzene ring is almost coplanar with one of the substituent benzene rings [dihedral angle = 1.74 (5)°] and is approximately orthogonal to the other benzene ring of the mol-ecule [dihedral angle = 86.
