, energy-dispersive spectrometry, and X-ray powder diffraction. Results show that Na effectively inhibited S catalysis during carbon–air/CO2 reactions, and S inhibited the catalysis of Na during carbon... (Na3AlF6) will contact with the carbon anode directly, which brings the Na with strong catalysis to coke [5, 6]. It has been proved that it is the Na bringing the catalysis, no Al or F. However......

. The mechanism of RE permeating into surface layers of steels and activation and catalysis effects of RE on thermo-chemical treatment process were studied. RE atom has considerable attraction for the iron atoms on the surface and diffuses inside by the vacancy mechanism. The activation and catalysis of RE in the thermo-chemical treatment process originally arise from the special electron-layer structure......
