资源简介：
Isomorphous incorporation of Cu(II) into a SAPO-34 framework allows for isolated active sites, which are active towards a range of catalytic reactions (such as deNOx and CO2-reduction). However, prolonged exposure to the gaseous precursors have shown that the catalytic activity decreases. Decreasing the diffusion distances of the gasses (by reducing the particle size) have demonstrated an improved catalytic activity and a slower decrease in catalytic activity. Shorter diffusion distances may prevent clogging of the porous structure and reduce the risk of poisoning the active site. Measuring the Cu K-edge in-situ for different diffusion conditions will reveal how the Cu(II) active sites changes during operation. Comparing the change in the active sites to the change in catalytic activity could therefore help decide how to design these catalyst to make them more active and more durable.
