Nanomaterials (NMs) with unique structures and compositions can give rise to exotic physicochemical properties and applications. Despite the advancement in solution-based methods, scalable access to a wide range of crystal phases and intricate compositions is still challenging. Solid-state reaction (SSR) syntheses have high potential owing to their flexibility toward multielemental phases under feasibly high temperatures and solvent-free conditions as well as their scalability and simplicity. Controlling the nanoscale features through SSRs demands a strategic nanospace-confinement approach due to the risk of heat-induced reshaping and sintering. Here, we describe advanced SSR strategies for NM synthesis, focusing on mechanistic insights, novel nanoscale phenomena, and underlying principles using a series of examples under different categories. After introducing the history of classical SSRs, key theories, and definitions central to the topic, we categorize various modern SSR strategies based on the surrounding solid-state media used for nanostructure growth, conversion, and migration under nanospace or dimensional confinement. This comprehensive review will advance the quest for new materials design, synthesis, and applications.
具有独特结构和组成的纳米材料（NMs）能够产生奇异的物理化学性质及应用。尽管基于溶液的方法取得了进展，但要大规模获取多种晶相和复杂组成仍具有挑战性。固态反应（SSR）合成具有很大潜力，因为它在可行的高温和无溶剂条件下对多元素相具有灵活性，且具有可扩展性和简便性。由于存在热诱导重塑和烧结的风险，通过SSR控制纳米级特征需要一种策略性的纳米空间限制方法。在此，我们描述用于NM合成的先进SSR策略，通过不同类别的一系列示例，重点关注机理见解、新型纳米级现象和基本原理。在介绍经典SSR的历史、关键理论以及该主题的核心定义之后，我们根据用于纳米结构生长、转化和在纳米空间或尺寸限制下迁移的周围固态介质，对各种现代SSR策略进行分类。这一全面综述将推动新型材料设计、合成及应用的探索。
