The Limitless Horizons of Space Art,luminescence spectra are assigned to these types of sites. Cu. ions on the channel intersection (type I) bind NO stronger than naked Cu. ions and it is suggested that these sites are catalytically active. A possible explanation of the higher catalytic activity of Cu/ZSM-5 compared to Cu/FER is proposed.作者: 迫擊炮 時間: 2025-3-22 16:34
