Structure and Properties of Epoxy Resin/Graphene Oxide Composites Prepared from Silicon Dioxide-Modified Graphene Oxide.

In this study, graphene oxide (GO) was modified via electrostatic interactions and chemical grafting by silica (SiO), and two SiO@GO hybrids (GO-A and GO-B, respectively) with different structures were obtained and carefully characterized. Results confirmed the successful grafting of SiO onto the GO surface using both strategies. The distribution of SiO particles on the surface of GO-A was denser and more agglomerated, while it was more uniform on the surface of GO-B.

Effective removal of humic acid by mesoporous Zr-MOF adjusted through SDBS.

Humic acid (HA) in makeup water is one of the important safety issues of high-parameter power plants. Herein, the Zr-based metal-organic frameworks (NH-UiO-66) was applied to remove humic acid in water. The mesoporous of NH-UiO-66 was controlled by surfactants sodium dodecyl benzene sulfonate (SDBS) to increase the adsorption of HA.
