摘要

纳米材料是纳米科学和纳米技术的支柱,为了充分发挥其在各种潜在应用中的潜力,需要建立简单、快速和具有成本效益的合成方法/路线。纳米材料合成的湿化学方法已被证明是最通用和有效的途径之一,可以精细地定制具有不同成分和结构复杂性的纳米晶体。微波辅助溶液路线代表了一种高效的湿化学方法来合成纳米材料,它提供了额外的优势,如快速体积加热,高反应速率,通过调整反应参数来控制尺寸和形状,以及能源效率。此外,微波合成中反应物的均匀加热使热梯度最小化,并提供均匀的成核和生长条件,从而形成具有均匀尺寸分布的纳米材料。本章介绍微波化学的基本原理及其在纳米材料催化合成中的应用。

Principles and Advantages of Microwave-Assisted Methods for the Synthesis of Nanomaterials for Water Purification
Nanomaterials are the pillars of nanoscience and nanotechnology and to realize their full potential in various potential applications, synthetic methodologies/routes need to be established that are simple, fast and cost-effective. Wet-chemical approaches for nanomaterial synthesis have proven to be among the most versatile and effective routes to finely tailor nanocrystals with varying compositional and architectural complexity. Microwave-assisted solution route represents an efficient wet-chemical approach for the synthesis of nanomaterials that offers additional advantages, such as rapid volumetric heating, high reaction rates, size and shape control by tuning reaction parameters, and energy efficiency. In addition, the homogenous heating of the reactants in microwave synthesis minimizes thermal gradients and provides uniform nucleation and growth conditions that leads to the formation of nanomaterials with uniform size distribution. This chapter deals with the basics of microwave chemistry and its applications towards the synthesis of nanomaterials for catalytic applications.
