A facile and robust strategy to fabricate organocatalyst-functionalized hollow double-shelled nano-bowl was developed for the first time by hard-templating synthesis. After the core was etched by DMF, the outer shell thicknesses below 50 nm and above 50 nm deformed into hollow nano-bowl and hollow nanosphere, respectively. Furthermore, the outer shell with the average thickness of 20–50 nm deformed into hollow double-shelled nano-bowl with a void between two semi-shells. However, the shell with the thicknesses below 20 nm severely deformed into hollow nano-bowl with no void owing to the overlapping of two semi-shells. Compared with hollow nanosphere and nano-bowl with no void, hollow double-shelled nano-bowl displayed superior catalytic performances owing to the thin shell thickness and a void between two semi-shells. In heterogeneous asymmetric Michael addition, the double-shelled nano-bowl exhibited good to excellent yields (86–98%), stereoselectivities (syn/anti = 81–93/19–7 and 93–99%ee syn) and good reusability.

通过硬模板合成法首次开发了一种简便而稳健的策略来制备有机催化剂功能化的中空双壳纳米碗。在通过DMF蚀刻核之后，低于50nm和高于50nm的外壳厚度分别变形为空心纳米碗和空心纳米球。此外，平均厚度为20–50 nm的外壳变形为空心的双壳纳米碗，两个半壳之间有空隙。然而，由于两个半壳的重叠，厚度小于20 nm的壳严重变形为空心纳米碗，没有空隙。与空心纳米球和没有空隙的纳米碗相比，空心双壳纳米碗由于薄的壳厚度和两个半壳之间的空隙而显示出优异的催化性能。syn / anti  = 81–93 / 19–7和93–99％ee syn）和良好的可重用性。
