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...

Yb/Er codoped Gd3Ga5O12 nanocrystalline upconverting phosphors were produced by the sol-gel pechini method at 1000 °C annealing temperature. The phosphor structure, morphological features, and luminescent properties of fabricated material studied using X-ray diffraction (XRD), transmission electron microscopy (TEM), high-resolution TEM (HR-TEM), photoluminescence measurements (PL). Upconversion...

This work consisted in the preparation of platinum-based catalysts supported on carbon (Vulcan XC-72) and investigation of their physicochemical and electrochemical properties. Catalysts of the C/Pt-Ni-Sn-Me (Me = Ru or Ir) type were prepared by the Pechini method at temperature of 350°C. Four different compositions were homemade: C/Pt(60)Sn(10)Ni(30), C/Pt(60)Sn(10)Ni(20)Ru(10), C/Pt(60)Sn(10)...

Barium-strontium titanate (BST) Ba0.6Sr 0.4 TiO3 and lanthanum-lithium titanate (LLT) La0.5Li0.5TiO3 nanopowders and thin films have been obtained via the modified Pechini route. Polyesterification and complexation processes of gel formation have been examined. Hypothetical models of coordinative polymers formed in sol-gel system have been suggested. It has been shown that BST and LLT solid sol...
