In Situ Spectroscopic and Computational Studies on a MnO-CuO Catalyst for Use in Volatile Organic Compound Decomposition.

In situ near-edge X-ray absorption fine structure (NEXAFS) spectroscopy and density functional theory calculations were conducted to demonstrate the decomposition mechanism of propylene glycol methyl ether acetate (PGMEA) on a MnO-CuO catalyst. The catalytic activity of MnO-CuO was higher than that of MnO at low temperatures, although the pore properties of MnO were similar to those of MnO-CuO. In addition, whereas the chemical state of MnO remained constant following PGMEA dosing at 150 °C, MnO-CuO was reduced under identical conditions, as confirmed by in situ NEXAFS spectroscopy.

NiO/CeO2-ZnO nano-catalysts for direct synthesis of dimethyl carbonate from methanol and carbon dioxide.

XNiO/CeO2(0.7)-ZnO(0.3) (X = 0, 1, 5, 10, and 15) nano-catalysts were prepared by a wet impregnation method with a variation of NiO content (X, wt%).
