Two-dimensional carbon architectures are attracting tremendous interests for various promising applications due to their outstanding electronic and mechanical properties, although it is a great challenge to rationally devise facile and operative methodologies to engineer their structural traits owing to complex synthetic processes. Herein, for the first time, we fabricate two-dimensional carbon nanoribbons via direct thermal exfoliation of one-dimensional Ni-based metal–organic framework (MOF) nanorods, in which interconnected graphitic carbon nanocages are self-assembled into a belt-like superstructure with carbon-encapsulated Ni nanoparticles immobilized on the surface. Due to the unparalleled structural superiority, the MOF-derived carbon nanobelts exhibit excellent catalytic performances in electrocatalytic hydrogen evolution. Importantly, the practical synthetic strategy may trigger the rapid development of carbon-based superstructures in many frontier fields.

石墨烯纳米笼的纳米带超结构，可有效释放电催化氢。

二维碳结构由于其出色的电子和机械性能而吸引了各种有前途的应用的兴趣，尽管由于复杂的合成过程，合理设计可行的和可操作的方法学来设计其结构特征是一个巨大的挑战。在此，我们首次通过直接热剥落一维Ni基金属-有机骨架（MOF）纳米棒来制造二维碳纳米带，其中互连的石墨碳纳米笼自组装成带状超结构碳封装的镍纳米粒子固定在表面上。由于无与伦比的结构优势，MOF衍生的碳纳米带在电催化制氢方面表现出出色的催化性能。重要的，
