Novel functions and advanced structure, where each single component could not be produced individually, can exhibit from the collective and synergistic behavior of component systems. This synergetic strategy has been successfully demonstrated for co‐assembly of polymer–polymer to construct hierarchical nanomaterials. However, differences in the natures of polymer and small molecules impose challenges...
The limited cycle life of Li–air batteries (LABs) with high areal capacity remains the chief challenge that hinders their practical applications. Here, the study proposes a hierarchical porous electrode (HPE) design strategy, in which porous MnO nanoflowers are built into mesopore/macropore electrodes through a combination of chemical dealloying and physical de‐templating procedures. The MnO nanoflowers...
The restricted charge transfer and slow oxygen evolution reaction (OER) dynamics tremendously hamper the realistic implementation of SnS2 photoanodes for photoelectrochemical (PEC) water splitting. Here, a novel strategy is developed to construct interfacial NCuS bonds between NC skeletons and SnS2 (CuNC@SnS2) for efficient PEC water splitting. Compared with SnS2, the PEC activity of CuNC@SnS...
Perovskite solar cells (PSCs) have attracted unprecedented attention due to their rapidly rising photoelectric conversion efficiency (PCE). In order to further improve the PCE of PSCs, new possible optimization path needs to be found. Here, quasi‐heteroface PSCs (QHF‐PSCs) is designed by a double‐layer perovskite film. Such brand new PSCs have good carrier separation capabilities, effectively suppress...
A robust and transparent silica‐like coating that imparts superhydrophobicity to a surface through its hierarchical multilevel self‐assembled structure is demonstrated. This approach involves iterative steps of spin‐coating, annealing, and etching of polystyrene‐block‐polydimethylsiloxane block copolymer thin films to form a tailored multilayer nanoscale topographic pattern with a water contact angle...
