Developing cost-effective non-noble catalysts for completely decomposing formaldehyde (HCHO) into harmless CO2 and H2O at room temperature remains great challenges indoor air purification. Herein, MnxCo3-xO4 solid solutions are prepared via the calcination of metal-organic frameworks (MOFs) with different Co/Mn molar ratios. The catalyst (Mn1Co1) achieves 100 % HCHO removal first time, possesse...

Selective catalytic reduction of NO with CO (CO-SCR) has been suggested as an attractive and promising technology for removing simultaneously from flue gas. Manganese-copper spinels are a CO−SCR material because the high stability redox properties spinel structure. Here, we synthesized CuxMn3−xO4 by citrate-based modified pechini method combining CuO MnOx, controlling molar Cu/Mn concentrations...

The solar-to-fuel energy conversion efficiency () of the MgxFe3-xO4 (x = 0.2-1.0) based CO2 splitting (CDS) cycle is estimated at steady reduction and oxidation temperatures equal to 1673 K 1273 K, respectively. analysis performed using experimental results reported in sol-gel-derived CDS cycle. redox nonstoichiometry allied with during steps determined on experimentally obtained results. Effic...

Perpendicular magnetic anisotropy (PMA) energy up to Ku = 6.1 ± 0.8 MJm−3 is demonstrated in this study by inducing large lattice distortion exceeding 3% at room temperature epitaxially distorted cobalt ferrite Co0.73Fe2.18O4 (001) thin films. Although the film materials include no rare-earth elements or noble metals, observed larger than that of neodymium-iron-boron compounds for high-performa...

Lanthanum substituted Ni-Zn ferrite nanoparticles (Ni0.5Zn0.5LaxFe1-xO4; 0.00 ≤x≤ 1.00) synthesized by sol-gel method were presented. X-ray diffraction patterns reveal the typical single phase spinel cubic ferrite structure, with the traces of secondary phase for lanthanum substituted nanocrystals. In addition, the structural analysis also demonstrates that the average crystallite size varied i...

A series of Bismuth doped Cobalt nanoferrites of chemical composition CoBixFe2-xO4 (where x = 0.00, 0.05, 0.10, 0.15, 0.20 & 0.25) were prepared by sol-gel combustion method and calcinated at 600 ̊C. The structural and morphological studies were carried out by using X-ray diffraction (XRD), Scanning Electron Microscope (SEM), Transmission Electron Microscopy (TEM), Energy Dispersive Spectroscopy...
