Amphiphilic Molecule Controlled Synthesis Of Nanomaterials At Room Temperature

The fabrication of nanoparticles is one of the important sections of nanoscience and nanotechnology, and also the base to investigate the distinctive properties and applications of nanostructures. Among all the synthesis methods to nanoparticles, liquid methods, especially the method using water as solvent, have attracted intensive interest because of their low cost and environmental benign characteristic. In this paper, by a controllable synthesis of amphiphilic molecule, we obtained cupric oxide (CuO) nano/micro superstructure film with hydrophilicity and superhydrophilicity surface on Cu foil via a solution-immersion process at room-temperature, and discussed Ag/AgX photocatalyst material under visible light.In recent years, functional surfaces with wettability have become very sought-after because of their value in fundamental research and industrial application. Wettability could be controlled in a rational manner by individually and simultaneously manipulating surface topography and chemical structure. This paper described how we obtained CuO superstructure film with hydrophilicity and superhydrophilicity surfaceds by a controllable synthesis of amphiphilic molecule on Cu foil via a solution-immersion process at room-temperature. The conditions of the experiment are simple and mild. A series of control experiments indicated that the concentration of NaOH, the concentration and the species of amphiphilic molecule had directly influenced the morphology and wettability of the product.Silver halide are photosensitive materials extensively used as source materials in photographic films. On absorbing a photon, a silver halide particle generates an electron and a hole, and subsequently the photogenerated electron combines with an Ag+ ion to form an Ag0 atom. Due to this instability under sunlight, which provides the very basis for chemical photography, silver halides are seldom used as photocatalysts. By the amphiphilic molecule controlled, we obtained Ag/AgX nano/micro material at room-temperature. It was found that Ag/AgBr is the best photocatalyst active and stable under visible light. Furthermore, A series of control experiments indicated that the species of amphiphilic molecule had directly influenced the photocatalyst active of silver halides. And in the polymer system, such as PVP or PEG, the photocatalyst active is the best.
