Fullerene-based low-dimensional (LD) heterostructures have emerged as excellent energy conversion materials. We constructed van der Waals 1T-MoS2/C60 0D-2D heterostructures via a one-pot synthetic approach for catalytic hydrogen generation. The interfacial 1T-MoS2-C60 and C60-C60 interactions as well as their electrocatalytic properties were finely controlled by varying the weight percentages of the fullerenes. 1T-MoS2 platforms provided a novel template for the formation of C60 nanosheets (NSs) within a very narrow fullerene concentration range. The heterostructure domains of 1T-MoS2 and C60 NSs exhibited excellent hydrogen evolution reaction (HER) performances, with one of the lowest onset potentials and ΔGH* values for LD non-precious nanomaterials reported to date.

定制范德华1T-MoS2/C60异质结构的界面相互作用，用于高性能析氢反应电催化

基于富勒烯的低维 (LD) 异质结构已成为出色的能量转换材料。我们通过一锅法合成催化制氢方法构建了范德华1T-MoS2/C60 0D-2D异质结构。通过改变富勒烯的重量百分比可以很好地控制界面 1T-MoS2-C60 和 C60-C60 相互作用以及它们的电催化性能。1T-MoS2 平台为在非常窄的富勒烯浓度范围内形成 C60 纳米片 (NSs) 提供了新模板。1T-MoS2 和 C60 NSs 的异质结构域表现出优异的析氢反应 (HER) 性能，是迄今为止报道的 LD 非贵重纳米材料的最低起始电位和 ΔGH* 值之一。
