Vesicle, a microscopic unit that encloses a volume with an ultrathin wall, is ubiquitous in ***, it remains a huge challenge to create its inorganic metal-based artificial counterparts. Here,inspired by the formation of biological vesicles, we proposed a novel biomimetic strategy of curling the ultrathin nanosheets into nanovesicles, which was driven by the interfacial strain. Trapped by the interfacial strain between the initially formed substrate Rh layer and subsequently formed RhRu overlayer, the nanosheet begins to deform in order to release a certain amount of strain. Density functional theory（DFT）calculations reveal that the Ru atoms make the curling of nanosheets more favorable in thermodynamics applications. Owing to the unique vesicular structure, the RhRu nanovesicles/c displays excellent hydrogen oxidation reaction（HOR） activity and stability, which has been proven by both experiments and DFT calculations. Specifically, the HOR mass activity of RhRu nanovesicles/c are 7.52 A mg（Rh+Ru）-1at an overpotential of 50 m V at the rotating disk electrode（RDE） level; this is 24.19 times that of commercial Pt/c(0.31 m A mgPt-1). moreover, the hydroxide exchange membrane fuel cell（HEmFc） with RhRu nanovesicles/c displays a peak power density of 1.62 W cm-2in the H2-O2condition, much better than that of commercial Pt/c(1.18 W cm-2). This work creates a new biomimetic strategy to synthesize inorganic nanomaterials, paving a pathway for designing catalytic reactors.

Popularization of lithium-sulfur batteries(LSBs) is still hindered by shuttle effect and volume ***, a new modularized sulfur storage strategy is proposed to solve above problems and accomplished via employing 100% space utilization host material of cobalt loaded carbon nanoparticles derived from ZIF-67. The modular dispersed storage of sulfur not only greatly increases the proportion of active sulfur,but also inhibits the occurrence of volume expansion. meanwhile, 100% space utilization host material can greatly improve the conductivity of the cathode, provide a larger electrolyte wetting interface and effectively suppress the shuttle effect. moreover, loaded cobalt particles have high catalytic activity for electrochemical reaction and can effectively improve the redox kinetics. The cell with new cathode host material carbonized at 650 ℃(ZIF-67(650 ℃)) exhibits superior rate performance and can maintain a high specific capacity of 950 m Ah/g after 100 cycles at 0.2 c, showing a good cycle stability.
