Synthesis of porous high-temperature superconductors via a melamine formaldehyde sacrificial template
Abstract
<p>Nanostructured high-temperature superconductors YBa<sub>2</sub>Cu<sub>3</sub>O<sub>6+δ</sub> and Bi<sub>2</sub>Sr<sub>2</sub>CaCu<sub>2</sub>O<sub>8+δ</sub> were synthesised using a melamine formaldehyde sponge as a sacrificial template, via three solution-based approaches. In the case of YBa<sub>2</sub>Cu<sub>3</sub>O<sub>6+δ</sub>, a modified Pechini method produced a material with a superconducting transition at 92 K and a specific surface area of 4.22 m<sup>2</sup> g<sup>−1</sup>. Further analysis with Hg porosimetry determined that the sponge exhibited a porosity of 82%. In the case of Bi<sub>2</sub>Sr<sub>2</sub>CaCu<sub>2</sub>O<sub>8+δ</sub>, this method produced a material that exhibited superconductivity at 86 K with a specific surface area of 9.62 m<sup>2</sup> g<sup>−1</sup>. Hg-porosimetry determined that the BSCCO sponge exhibited a porosity of 78%.</p>
