In article number 2002753, Lirong Zheng, Aijuan Han, Junfeng Liu and co-workers report the development of a manganese single-atomic-site catalyst anchored on porous nitrogen-doped carbon with Mn-N4 structure, which exhibits superior electrocatalytic activity stability for alkaline oxygen reduction reaction (ORR) in zinc-air batteries. Furthermore, operando XAFS is applied to uncover mechanism u...

Nanostructured thin films on a silicon substrate were obtained ceramic of zinc oxide doped with manganese by high-frequency periodic pulsed laser action f ~ 10–15 kHz, wavelength λ = 1.064 μm at power density q 150 MW/cm2 in vacuum chamber p 2.7 Pa. The surface morphology and the elemental composition studied using atomic force microscopy, scanning electron X-ray spectral microanalysis. Feature...

Mn doped ZnO nanocomposite thin film coated on glass by a simple spin-coating method was used to degrade an azo textile dye from aqueous environment. Mn doped ZnO nanocomposite thin film was characterized by means of X-ray diffraction (XRD) and scanning electron microscopy (SEM). The photo-reduction activity of photocatalyst was evaluated using an azo textile dye as organic contaminant irradiat...

Chemical Looping Combustion (CLC) is a promising carbon capture technology to contribute the development of BioEnergy with Carbon Capture and Storage (BECCS) technologies. In CLC, oxygen needed for combustion supplied by solid carrier. During last years, intensive research has been conducted identify potential carriers. Iron manganese-based minerals allowed obtaining high CO2 efficiencies, but ...
