从SEM图中可以看出TpPa-1 FAG由中空微米级COF纤维交联缠绕组成,在其表面生长有大量的纳米级COF纤维(图2b-c)。TEM及选区电子衍射结果确认了微米与纳米COF纤维的结晶度(图2d-f)。XRD与FT-IR结果进一步表明PAN的完全去除以及TpPa-1 COF的成功制备(图2g-h)。通过氮气吸附-脱附等温线可以看出,与TpPa-1粉末相比,TpP...
synthesized by template-assisted replication of nanometer sized ZnO-nanorods. The hollow structures composed of microporous TpPa shells have high periodicity, moderate porosity, chemical stability and capsule shaped morphology as revealed by X-ray diffraction, porosity measurements, and SEM and TEM ...

1)通过球差矫正高角环形暗场STEM清晰地直接观察到MS-c的存在,并利用TEM图像和AC HAADF-STEM图像得到MS-c在MS-c@TpPa-1中的尺寸分布图,确认MS-c的平均尺寸约为0.98 nm。 2)研究表明MS-c中的Mo原子与TpPa-1-COF中的不饱和配位N原子之间形成了Mo−N的配位键,在原子层面上明确了TpPa-1-COF与MS-c的之间...
