Here, we report the in situ direct growth of a graphene/hexagonal boron nitride (hBN) heterostructure on a SiO2 substrate without a metal catalyst by chemical vapor deposition (CVD). The hBN could be grown easily on a SiO2 substrate, while graphene growth was difficult and time-consuming as graphite could be grown only partially on the dielectric substrate, even after 5 h. Graphene was grown directly...
Heteropoly acids have attracted increasing attentions in oxidative desulfurization (ODS) field, but the solubility and low surface area hindered their applications. Moreover, bulk silicotungstic acid (HSiW) was less researched, owing to its relative lower activity. Herein, a layered-structure hexagonal boron nitride (h-BN) was employed for dispersion of HSiW by impregnation method. Interestingly,...
Hexagonal boron nitride (h-BN), a layer structure material, has gained increasing attentions as a support. Herein, a few-layer h-BN is constructed and employed as an interlayer confining support for heterogenization of phosphotungstic acid (HPW/h-BN). The obtained HPW/h-BN is applied in oxidative desulfurization (ODS) and a ∼100% of sulfur removal can be achieved. Detailed experiments show that porous...
