Using periodic DFT-D3-U methods, the present work give a mechanistic insight into the high silica B-, Al-, Ga- and Fe-MOR with H, Li, Na, and K as charge balance ions. The acid properties of the zeolite were probed via NH3 and pyridine adsorption. It is found that the charge balance ions influence the location of the trivalent ions, the cell volumes, as well as the synthesis difficulty of the zeolites...
In this paper, the sol-gel method is used to prepare the nano GaN powder. In which we use Ga2O3 as the gallium source, citric acid as the chelating agent to prepare the former drive material, after to be jello, we put it into NH3 environment to get the GaN sample. The two photoluminescence peaks by PL show that GaN has good optical performance, through the first principle calculation we know that...
