Photocatalytically Active YBa₂Cu₃O_7−x Nanoparticles Synthesized via a Soft Chemical Route

Abstract

YBa2Cu3O7−x(YBCO) nanoparticles (NPs) were synthesized via a soft chemical approach and they were found photocatalytically active at room temperature. Using metal acetate as precursors, a well-designed soft chemical procedure was carried out to produce YBCO NPs. The very small particle size and/or large number of defects might have led the NPs to semiconductors with vigorous photocatalytic activities. This work provides a direct and efficient route to obtain multifunction in YBCO based nanomaterials which are based on specific size and surface effects.

Effect of Processing Parameters on the Morphology, Particulate, and Superconducting Properties of Electrospun YBCO Nanostructures

“…Owing to developments in nanoscience and technology, YBCO in nanoscale was fabricated by employing various techniques with single crystal structure, pure, uniform, and high superconducting performance [6,7]. Techniques such as pulsed laser deposition (PLD), chemical vapor deposition (CVD), electron-beam lithography (E-beam) and anodic aluminum oxide (AAO) template were used for the synthesis of YBCO at nanoscales [8][9][10][11][12]; however, most of these techniques are complex and expensive. In contrast, electrospinning is relatively a simple technique and appears to be effective, cheap, controllable, and versatile diverse morphologies and functionalities [13,14].…”

Fabrication of superconducting YBCO agglomerated particles (ANPs) by electrospinning

“…Several structures of the superconducting YBa 2 Cu 3 O 7-δ (YBCO) at nanoscale were synthesized successfully by employing various techniques with structure, pure, uniform and, high performance [8]. Structures of YBCO superconductor like fibres, wires, tube, tape and particles have been prepared [9,10]. Many reports have been published introduced the preparation of YBCO at the nanoscale by several techniques such as pulsed laser deposition (PLD), chemical vapor deposition (CVD), electron-beam lithography (E-beam) and anodic aluminum oxide (AAO) template, most of these techniques are complex and expensive [11][12][13][14][15].…”

Microwave-assisted synthesis and critical analysis for YBa2Cu3O6+δnanoparticles

“…35) with a charge redistribution along the c-axis [2], leading to the generation of hole carriers in the a-b plane and the occurrence of superconductivity. Numerous studies have been carried out to understand the effects of δ on the physical properties of bulk YBCO, but only a few for YBCO nanoparticles (NPs) [3][4][5][6][7][8][9][10][11][12][13].…”

“…In the past, various wet chemical methods such as the soft chemical approach [13], citrate-gel [8], and citrate pyrolysis [9,10,12] were often used for the synthesis of YBCO NPs. Alternatively, a physical method such as microwave heating could be effective, but is less discussed [18].…”
