The microsized perovskite-like oxide La 2−x Sr x CuO 4 (x=0, 1) single crystallites with a rod-like morphology were fabricated with KOH as the alkaline source at a hydrothermal temperature of 180–260°C and after calcination at 850°C, and characterized by means of the XRD, BET, SEM, SAED (selected area electron diffraction), O 2 -TPD, and H 2 -TPR techniques...
The YBa2Cu3O7 nano/microsized single crystallites with spherical and rod-like morphologies were fabricated hydrothermally. The catalytic performance of the materials was evaluated for methane combustion. It is shown that there was a clear relationship between the α-oxygen desorption or initial H2 consumption rate and catalytic activity. The single-crystalline perovskite-like cuprate catalysts outperformed...
