  Beijing Institute of Technology, Feb 17th, 2020: Recently, the team of Zhang Jiatao, who is the Dean of the School of Chemistry and Chemical Engineering, BIT, published a review entitled Nanointerface Chemistry: Lattice-Mismatched-Directed Synthesis and Application of Hybrid Nanocrystals in the top international journal Chemical Reviews (Impact Factor 54.3). A comprehensive and systematic explanation of the important role of the lattice mismatch degree in the synthesis and application of hybrid nanocrystals.

  Hybrid nanocrystals, which are based on metal or semiconductor materials of nanometer or quantum scale, have important application prospects in catalysis, energy conversion and storage, photoelectric devices, biomedical diagnosis and treatment, quantum information processing and other fields. A large number of studies have shown that the lattice structure and electronic properties of the hybrid interface between different components play a key role in the overall performance of the hybrid nanocrystals. The more important reason is that the lattice mismatch degree at the interface determines the different mechanism of crystal growth from the thermodynamics. Therefore, the lattice mismatch degree is an important parameter in the synthesis and application of hybrid nanocrystals. It is not only closely related to the difficulty of hybrid nanocrystals synthesis, but also has a direct impact on the lattice defects and lattice strain state at the interface of the synthesized materials, so it can be further used to control the electronic and optical properties of hybrid nanocrystals.

  Based on detailed literature research, the team reviewed the research results accumulated in the research of hybrid nanocrystals synthesis under the large lattice mismatch degree (>40%) in recent years. In this review, the synthesis and performance control methods of metal@metal, semiconductor@semiconductor and metal@semiconductor hybrid nanocrystals under three different conditions, namely, small lattice mismatch degree (<5%), medium lattice mismatch degree (5%-20%) and large lattice mismatch degree (>20%), are systematically analyzed under different lattice mismatch degree (Figure 1). For example, the epitaxial seed growth method and the cation exchange method can be applied to the controllable synthesis of metal@metal and semiconductor@semiconductor hybrid nanocrystals under lattice mismatch less than 20%. Based on the original “breaking the thermodynamic limit” reverse competitive cation exchange methodology, the team proposed a new non-epitaxial growth strategy, breaking the lattice mismatch degree limit of hybrid-nanocrystals-epitaxial growth, breaking the critical dimension thickness of hybrid-nanocrystals-epitaxial growth, and preparing metal@single crystal semiconductor core-shell nanocrystals with different shapes and thicknesses, which provides an effective method for the control of nanointerface under large lattice mismatch degree. Besides, this review also discusses in detail how to regulate the physical and chemical properties of hybrid nanocrystals in catalysis, luminescence, energy conversion and other applications through changing the lattice mismatch degree, and shows the outstanding performance advantages of non epitaxial metal@semiconductor heterogeneous nanocrystals with ordered atomic level heterogeneous interface in quantum information, clean energy, medical diagnosis and treatment applications.

  The above research results are supported by the platform of Beijing Key Laboratory of Structural Controllable Advanced Functional Materials and Green Application and Experiment Center of Advanced Materials (ECAM), School of Materials Science and Engineering, funded by the National Natural Science Foundation of China (Grant No. 51702016, 51631001, 51872030, 21643003, and 51501010) and the Support Plan for Innovative Talents of the Institute of science and technology, BIT.
