替代传统的焦耳加热，电磁波和粒子束形式的辐射提供了一种有前途的途径，以高的时间效率，简单性，可扩展性和环境友好性为纳米材料的绿色合成和改性提供能量。原子/分子和光子/高速粒子之间的基本相互作用导致了几种辐射效应，为化学反应和物理过程铺平了道路。本文综述了辐射诱导金属、金属化合物和碳材料的合成与改性研究进展。我们涵盖电磁波和亚原子粒子束全谱的电离和非电离辐射。前者包括γ射线和X射线、电子束、中子束和其他高能粒子束，而后者包括紫外线、可见光、红外线和微波辐射。根据辐射源的能量和强度，我们制定不同的辐解，光解，撞击，和光热效应介导的合成和修改。重点放在辐射的按需利用和所得材料结构参数（尺寸、组成和分散性）的精细控制上。最后，我们提出了改进的新设计和实施的辐射技术，合成和修改先进的无机纳米材料。
Alternative to conventional Joule heating, radiation in the forms of electromagnetic waves and particle beams offers a promising route to energize the green synthesis and modification of nanomaterials with high time efficiency, simplicity, scalability, and environmental friendliness. Fundamental interactions between the atoms/molecules and the photons/high-velocity particles lead to several radiation effects that pave the way for chemical reactions and physical processes. Here, a comprehensive review is provided to summarize numerous studies concerning radiation-induced synthesis and modification of metals, metal compounds and carbon materials. We cover both ionizing and non-ionizing radiation of the full spectrum of electromagnetic waves and subatomic particle beams. The former includes γ- and X-rays, electron beams, neutron beams, and other high-energy particle beams, while the latter consists of ultraviolet, visible light, infrared, and microwave radiation. Depending on the energy and intensity of the radiation source, we formulate distinct radiolysis, photolysis, knock-on, and photothermal effects that mediate the synthesis and modification. Emphasis is placed on the on-demand utilization of radiation and the fine control of structural parameters (size, composition and dispersity) of resulting materials. Lastly, we propose improvements for the novel design and implementation of radiation techniques to synthesize and modify advanced inorganic nanomaterials.
