Selenium is an essential trace element nutrient for human life; but it can be extremely toxic if taken excess. Various adsorbents have been applied for the removal of selenium from water but performed poorly in Se (VI) removal, which is more bioavailable and more difficult to remove. Herein, we reported a new method to prepare the dendrimer, a different generations of poly (amido amine), functionalized...
Hierarchical porous activated carbon (AC) was obtained by the carbonization of dried spinach leaves followed by activation with KOH. The product was characterized by nitrogen adsorption, FT-IR, FE-SEM and electrochemical tests. The AC has a dominant number of micropores, a medium number of mesopores and a few macropores with a specific surface area up to 2616m2/g and a large number of oxygen-containing...
The microstructures of mesoporous carbon nanofibers were characterized by scanning electron microscopy, transmission electron microscopy, nano-Raman, nitrogen adsorption–desorption and optical transmission. They possessed a high specific surface area 840m 2 g −1 and a 1.07eV band gap. All mesoporous carbon nanofiber network can act as the channel material in p-type field-effect transistor...
