Abstract:

Principles of plasma electrolytic oxidation of the AL25 aluminum alloy in diphosphate alkali solutions containing cobalt(2+) cations are discussed. It has been established that a variation in the concentration of the electrolyte components provides the formation of mixed-oxide coatings consisting of the basic matrix materials and the cobalt oxides of different content. An increase in the cobalt oxide content in the coating is achieved by the variation in electrolysis current density as well as the treatment time due to both the electrochemical and thermo-chemical reactions at substrate surface

Abstract:

Design of high efficiency energy accumulators has recently become an important issue of science and technology. Electrochemical capacitors are distinguished for a greater power, a longer self-discharge time and a greater number of work cycles as compared to those of traditional electrochemical batteries. Effective supercapacitors are mainly produced of RuO2, which is distinguished from other metals for its nearly highest specific capacity, however its practical application is limited by its high price, therefore efforts are under way to find cheaper substitutes.

Abstract:

The three-way catalyst (TWC) greatly reduces emissions of hydrocarbons, carbon monoxide and nitrogen oxides from gasoline powered vehicles. However up to 80% of all hydrocarbons are emitted in the first 120 seconds after the engine is started, before the TWC achieves light-off. Catalysts which are active at lower temperatures offer a potential solution to this ‘cold-start’ problem. Co3O4 is one of the most active transition metal oxide catalysts for the total oxidation of hydrocarbons. In this work the synthesis of bulk and supported cobalt oxide catalysts has been investigated. The catalysts

The practical application of DMS requires a Curie temperature well above room temperature and an intrinsic ferromagnetism. There are several types of DMS materials.

碩士<br>國立清華大學<br>化學系<br>90<br>ABSTRACT Catalysts of Co3O4 and Au/Co3O4 were prepared for sensing materials of CO sensor. Two types of CO sensors i.e. Solid electrolyte (SES) and semiconductor (SCS) were developed. For the sake of applicability, low working temperature, high sensitivity, good selectivity, fast response time and low cost are expected from the prepared sensors. Sensitivity of prepared catalysts towards CH4 and H2 also were tested in the experiment. In SES, yttria stabilized zirconia (YSZ) was used as the conductor of oxygen ions. Different oxides i.e. CoOx, S

In addition, transition metal (TM) doped ZnO has also been considered as a potentials for realized magnetic semiconductor for spintronics application. However, whether coating a TM on semiconductor nanostructures can make them ferromagnetic by interfacial charge transfer is also worthy of investigation. 　　In this work, the room-temperature ferromagnetic ZnO spin-polarized semiconduct

碩士<br>國立中正大學<br>應用地球物理研究所<br>104<br>Nano cobalt oxide was synthesized as an anode material for super capacitor electrode by a microbial induced precipitation method. The microorganism, Bacillus pasteurii, secreted high active urease which performed the hydrolysis of urea to an ammonia ion and a carbonate ion that subsequently produced precipitates with cobalt ion. The effects of concentration of cobalt ion and dilutions of bacterial broth for precipitation yield were investigated. The optimum parameters for the production yield were 0.1 M cobalt ion and original bacterial broth (named as 01BP3
