Synthesis And Performance Of Cu_xO/h-BN Compound

With the development of nano science and technology,nano copper oxide has attracted more and more attention,because size changes result in the unique physical and chemical properties change.However,the strong interactions of the oxides particles,especially for their nanostructured counterparts,cause them to clump and aggregate,thereby deteriorating the relevant properties.We found that the hexagonal boron nitride?h-BN?is a good sheet of basement setoff/stabilizer,which can be used to disperse nanoparticles.Compared with the traditional chained stabilizer,h-BN can expose particles with more of the active surface.The paper mainly revolves around Cu_xO and h-BN,after calcinations,Cu_xO can be uniformly scattered over the h-BN.This move would not only shed light on our mechanistic understanding of chemical formation of the composites in general,but also allow us to better integrate these merits of h-BN and metal oxides in advanced device design and practical applications.This thesis mainly carried out the following three aspects:?1?we reported the feasibility using Cu₂O/h-BN composites as a catalyst for the reduction of p-nitrophenol to p-aminophenol.The Cu₂O/h-BN composites are thus obtained by dispersing Cu₂O octahedrons on the surfaces of two-dimensional h-BN nanosheets.The-OH and-NH groups on the surfaces of h-BN nanosheets are found to be beneficial for anchoring Cu₂O octahedrons.Moreover,the Cu₂O/h-BN composites exhibit superior activity for the reduction of p-nitrophenol to pure Cu₂O crystals and h-BN nanosheets.?2?The antibacterial properties of Cu₂O/h-BN composites were carried out:E.coli,P.aeruginosa.B.suhtilis and S.aureus were chose to test the contacted antibacterial of the compound.Bacterial surface morphology before and after the test were observed,preliminary exploration of the mechanism of the antibacterial effect of Cu₂O/h-BN compound.?3?The Catalytic performance from ammonia borane hydrolysis of CuO/h-BN composites were investigated:In order to further understand the Cu_xO,in the presence of h-BN nanosheets,H₂O₂ was used to synthesis supported CuO/h-BN compound,which was found to be superior active for the generation of hydrogen from ammonia-borane to pure Cu₂O crystals and h-BN nanosheets.Innovation of this paper:The supported catalyst between CuXO and a new 2D sheet material not only shed light on our mechanistic understanding of chemical formation of the composites in general,but also has significance for future research.
