Fabrication and photocatalysis of TiO2-graphene sandwich nanosheets with smooth surface and controlled thickness

Facile hydrothermal synthesis of Bi/BiOBr composites with enhanced visible-light photocatalytic activities for the degradation of rhodamine B

“…The intercepts of the tangent to the x-axis will give a good approximation of the band gap energies for the BiOBr and Bi/BiOBr samples. The Photoluminescence emission spectrum was usually used to research the efficiency of charge trapping, immigration, transfer, and to understand the behavior of electron-hole pairs [22]. Fig.…”

Enhanced photoactivity of graphene/titanium dioxide nanotubes for removal of Acetaminophen

“…In order to prepare GR-TNT hybrids, generally two methods are used: using Ti and graphene precursors [25,26] and direct compounding [27]. Compared to the former method, direct compounding is easy and time-saving.…”

Preparation and characterization of graphene oxide/Ag2CO3 photocatalyst and its visible light photocatalytic activity

“…Graphene oxide (GO) is a derivative of graphene and it was made of graphite oxide stripping and formation of graphene single chips [30]. Existing literatures show [31][32][33][34][35][36][37][38] that coupling the semiconductor catalysts with different carbon materials, such as carbon nanotubes, graphene and graphene oxide can effectively improve the photocatalytic activity of semiconductor catalyst. For example, Dong et al [39] fabricated a series of nitrogen-doped graphene-Ag 2 CO 3 composites.…”
