Progress of preparation and application of nanoscale zero-valent iron
摘要
Abstract
Nanoscale zero-valent iron catalytic materials have advantages of low cost,high reaction activity,high specific surface area and excellent adsorption properties. The excellent performances of these materials in various environmental pollutants(e.g. heavy metals,inorganic anions,radioactive elements,halogenated organic compounds,nitroaromatic compounds and endocrine-disrupting chemicals)remediation through different degradation mechanisms have made them be regarded as a new type of material that having broad application prospect. In this review,the typical preparation methods,including physical method,chemical liquid phase reduction method,thermal decomposition method,carbothermal synthesis and polyol process,and novel green synthesis technology,of nanoscale zero-valent iron are introduced in detail. Moreover,the applications as well as the reaction mechanism and efficiency of nanoscale zero-valent iron in environmental pollution treatment and catalysis are summarized. In addition,some unresolved scientific problems including the oxidation and the agglomeration of nanoscale zero-valent iron are mentioned. It also suggests that the future research should be focused on the improvement or development of new synthetic method to reduce the cost and to extend the application field of the nanoscale zero-valent iron materials.关键词
