Plant leaves represent a unique 2D/1D heterostructure for enhanced surface reaction and efficient mass transport. Inspired by plant leaves, a 2D/1D CoO x heterostructure is developed that is composed of ultrathin CoO x nanosheets further assembled into a nanotube structure. This bio-inspired architecture allows a highly active Co2+ electronic structure for an efficient oxygen evolution reaction...

The two-dimensional molybdenum disulfide (MoS2) nanosheet has been extensively studied as a novel photothermal transducing agent. However, top-down exfoliation to produce MoS2 nanosheets is inefficient, and MoS2 nanosheet surface modification procedures are complex.
