Hydrogen Evolution: Self‐Limited on‐Site Conversion of MoO₃ Nanodots into Vertically Aligned Ultrasmall Monolayer MoS₂ for Efficient Hydrogen Evolution (Adv. Energy Mater. 21/2018)

In article number 1800734, by Yun Zhang, Jin-Song Hu and co-workers, a self-limited on-site conversion strategy is developed to achieve well-dispersed ultrasmall MoS2 monolayers. By vertically-aligning and downsizing these monolayers to maximize the accessible highly-active catalytic sites, they exhibit superior electrocatalytic performance for hydrogen evolution, suggesting that the present strategy opens up opportunities for exploring well-dispersed ultrasmall nanomaterials as efficient catalysts.
