Summary: Porous nanopetals of MnMoO4 with oxygen vacancies exhibit higher specific surface area and more diverse pore size distribution compared to MnMoO4 nanopetals. The introduction of oxygen vacancies leads to decreased energy band gap, increased electron state distribution at Fermi energy level, enhanced specific capacitance, and improved capacitance retention rate for MnMoO4-OV. These results demonstrate the beneficial effects of oxygen vacancies on the supercapacitive performance of MnMoO4-OV.

Summary: Recently, ceramic fuel cells (CFCs) have shown great potential for both small- and large-scale applications. However, the low-oxygen reduction response of cathode materials hampers the low operating temperature of CFCs. In this study, a semiconductor based on La and Ce co-doped SrCoO3 was developed and embedded in porous Ni-foam to investigate its electrochemical properties. The cathode of La0.2Sr0.8Co0.8Ce0.2O3-delta pasted on porous Ni-foam exhibited low-area-specific resistance and excellent ORR activity at temperatures as low as 450-500 degrees C. The device achieved an impressive fuel cell performance of 440 mW-cm(-2) at 550 degrees C using H-2 fuel and atmospheric air. It also showed good activation energy and improved ORR activity compared to other similar materials. These findings contribute to the development of cobalt-free electrocatalysts for low-temperature solid oxide fuel cells (LT-SOFCs).
