纳米WC粉体的制备及其催化应用
The progress in the preparation and catalytic application of WC nano-powders
摘要
Abstract
The preparation methods and catalytic application of tungsten carbide ( WC) nano-powders were described in this paper. Based on the analysis of three kinds of preparation ways, liquid-phase method and gas-phase method have become the mainstream of the preparation methods of nano-WC powders. Among them, the spray-drying technology, because of the lower cost of its process, has the potential of industrial research. Chemical vapor deposition ( CVD) has been systemically investigated as its process is simple and product has some characters such as high purity, good dispersity, small diameter and narrow size distribution, even if its cost is higher and device is sophisticated. RF-PCVD has two distinctive advantages; continuous flow at high temperature and rapid quenching, which is one of the more promising ways to be industrial studied. WC catalyst has electronic catalytic activation " similar to Pt" and is taken as the alternative of noble metal Pt, used in acid fuel cell and dehydrogenation and hydrogenation reaction.关键词
