    In article number 1805976, Lei Fu and co‐workers demonstrate the disassembly of 2D vertical heterostructures with the activation of specific disassembly promoters (DPs) and the weakening of the interlayer van der Waals interaction, which initially establishes the inverse process to 2D material assembly. The unique disassembly process has remarkable prospects toward the modification and functionalization of 2D materials, which opens up a novel pathway to functionally integrated devices.

  • Jinxin Liu, Lei Fu*, "Controllable Growth of Graphene on Liquid Surfaces", Adv. Mater. 2019, 31, 1800690. 

    As Lei Fu and Jinxin Liu discuss in article number 1800690, the exciting progress in controlled growth, etching, self‐assembly, and delivery of graphene on a liquid surface can be achieved, promoting its future industrial applications. The poem in the cover translates as “The pools in south China are suitable for gathering lotus. How dense and flourishing are the lotus leaves!” The lotus leaves floating in the pools represent graphene single crystals grown on liquid substrates.

    The two-dimensional (2D) GaN single crystals can be grown on liquid metals with urea as precursors via a surface-confined nitridation reaction strategy, which can pave the way to further explore the electronic and optical properties of GaN in the 2D limit.

    In article number 1801690, Lei Fu and co‐workers present a new catalyst; nanometric Ni5P4 clusters nested on NiCo2O4 nanoflakes. Due to the small energy barrier of water dissociation on NiCo2O4 and the low hydrogen adsorption free energy of Ni5P4, the as‐demonstrated nanocomposite exhibits superior catalytic activity for alkaline water electrolysis, which outperforms many other non‐noble electrocatalysts.

    In article 1800181, Mengqi Zeng, Lei Fu, and co‐workers review a class of high‐efficiency atomic scale materials (ASMs) catalysts. The distinct structural characteristics endow them with great catalytic advantages, especially the maximum atomic utilization. ASMs catalysts have demonstrated their superior catalytic performance in various core catalytic reaction systems. It is envisioned that these will open up a new territory in catalysis.

  • Mengqi Zeng, Lei Fu*, "Controllable Fabrication of Graphene and Related Two-Dimensional Materials on Liquid Metals via Chemical Vapor Deposition", Acc. Chem. Res. 2018, 51, 2839-2847.

    A change of the metal catalyst in the physical state from the traditional solid to liquid brings about a qualitative change and improvement in the controllable fabrication of two-dimensional (2D) materials. The unique self-limited growth, self-assembly, and sliding transfer behaviors of 2D materials on liquid metals are fully exhibited. See article by Lei Fu and Mengqi Zeng (10.1021/acs.accounts.8b00293).

    In article number 1804559, Lei Fu and co‐workers enforce a smart self‐adapting wettability (SAQ) of ReS2 under sustained light irradiation, which breaks the stereotype that a single stimulus leads to a monotonic change in properties or structure. This unique SAW provides a brand‐new insight to broaden the applications of responsive materials, which will undoubtedly pave a novel way in further device optimization.

    A liquid metal solvent based co-segregation strategy was proposed to fabricate a high uniformity of 2D WC crystals embedded in the few-layer graphene by chemical vapor deposition (CVD) in one step. In addition, the efficient catalytic ability of the 2D WC for the hydrogen evolution, for the first time, was experimentally exhibited.

    A Cu-assisted self-limited growth method is proposed to achieve the ultra-fast growth of strictly monolayer and high-quality WSe2 crystals, by L. Fu and co-workers on page 5741. Cu can prevent the layer accumulation since it occupies the surface of the WSe2 crystals, thus the W atoms can only adsorb on the edge site to achieve the size extension.

    A hexagonal-boron nitride (h-BN) self-aligned single-crystal array (SASCA) is reported by Lei Fu and co-workers in article number 1500223. The h-BN SASCA shows orderly alignment and uniformly distribution. Moreover, it exhibits highly accordant spatial orientation and homogenous domain size, which can realize highly integrated and individually switching field-effect transistors (FETs) when serving as gate dielectrics. Additionally, circular h-BN single-crystals, which are considered as the building blocks of h-BN SASCA, are also observed.

    We first synthesized ultra-uniformly distributed vertical ReS2 nanowalls grown on three-dimensional graphene foam by chemical vapor deposition. The ReS2 nanowalls expose more active sulfur edge sites, which improves easy lithium intercalation and deintercalation, as well as shorten the pathways and facilitates fast diffusion of both Li+ and electrolyte ions.
