Pyrogallic acid (PG) was used as a modeling carbon source in fabricating nano‐structured hollow carbon materials (HCMs) by a chemical vapor deposition (CVD) method. We found that non‐isothermal deposition can improve the integrity of the obtained HCMs. The different pyrolyzed species from PG under varied temperatures lead to the temperature‐dependent deposition yield, graphitization degree and morphology of the HCMs. HCMs including hollow spheres of varied sizes, cubic boxes with yolk‐shell structure, nanotubes, mesoporous particles and double‐shelled fibers, were prepared by using different templates, demonstrating the universality of this strategy. The carbon source has been extended to other plant polyphenols. The abundant and renewable solid precursors for CVD method endow this strategy excellent operation safety, improved storage and transportation convenience and low cost, and would boost the production of morphology‐ and size‐controlled HCMs and their applications in the fields such as water treatment, electrode materials, adsorbent, drug delivery, and so forth.

非等温化学气相沉积多酚的纳米结构空心碳材料

邻苯二酸（PG）被用作通过化学气相沉积（CVD）方法制造纳米结构空心碳材料（HCM）的模型碳源。我们发现非等温沉积可以改善所获得的HCM的完整性。PG在不同温度下的不同热解物种导致HCM的温度依赖性沉积产率，石墨化程度和形态。HCM包括不同大小的空心球，具有卵黄壳结构的立方盒，纳米管，中孔颗粒和双壳纤维，是通过使用不同的模板制备的，证明了该策略的普遍性。碳源已扩展到其他植物多酚。CVD方法具有丰富且可再生的固体前驱物，因此该策略具有出色的操作安全性，
