Photocatalytic Composite Materials Based on Graphene and Titanium Oxide Prepared by Different Methods
Titanium(IV) oxide graphene [1] or graphene oxide nano composite [2] were prepared by one-pot thermal hydrolysis of suspension graphene or graphene oxide nanosheets and titanium oxide in three different forms as a starting materials. Graphene nanosheets were produced in a large quantity from natural graphite using a high intensity cavitation field in a pressurized ultrasonic reactor [3]. The gr...
متن کاملOverpotential deposition of Ag monolayer and bilayer on Au(1 1 1) mediated by Pb adlayer underpotential deposition/stripping cycles
Ultra-thin Ag films on the Au(1 1 1) surface were prepared via overpotential deposition (OPD) in the presence of Pb2þ ions. By carrying out repetitive Pb adlayer underpotential deposition (UPD) and stripping cycles during Ag bulk deposition, the two-dimensional growth of Ag films was significantly enhanced in high OPD. The Ag monolayer sample was made by comparing the voltammetry curves, in whi...
متن کاملSb Surface Modification of Pd by Mimetic Underpotential Deposition for Formic Acid Oxidation
The newly proposed mimetic underpotential deposition (MUPD) technique was extended to modify Pd surfaces with Sb through immersing a Pd film electrode or dispersing Pd/C powder in a Sb(III)-containing solution blended with ascorbic acid (AA). The introduction of AA shifts down the open circuit potential of Pd substrate available to achieve suitable Sb modification. The electrocatalytic activity...
متن کاملNovel Polyimide Materials Produced by Electrospinning
Due to one-dimentional nanostructures’ unique properties and their intriguing applications, there has being a great demanding on the technologies which are able to produce such structures. Among the applicable strategies, electrospinning seems to be the simplest approach to generate continues nanofibers with ultrathin and uniform diameters (Li & Xia, 2004). Electrospinning is a spin technology ...
متن کاملMR imaging artifacts produced by dental materials.
This report evaluates a variety of dental materials with respect to MR imaging artifacts and their mechanisms of production. A 0.15-T superconducting system and an MR phantom were used in assessing imaging artifacts. Several in-vivo studies were also carried out. The dental materials were analyzed for composition and magnetic permeability and the results were compared with the artifacts produce...
