利用FT-IR,XRD,SEM,TEM,TGA,BET和XPS对产物进行表征,表明材料的成功制备.根据表征结果可以看出,经磷酸功能化修饰后的PCN-224-HEDP依然保持规整的晶体结构.比表面积与孔径略有降低,这是由于孔道内部接枝了大量的磷酸官能团.对PCN-224-HEDP进行水溶液中铀吸附性能研究,其最大吸附容量为295 mg·g-1.通过对PCN-224...
Based on the well-matched electronic band structures, a staggered S-scheme charge-transfer model was revealed through density functional theory (DFT) calculations, in situ irradiation X-ray photoelectron spectroscopy (ISI-XPS), and fluorescence decay analysis. This band-bending and charge-migration ...
