英文摘要：

Different types of intercalated agents can be in-situ intercalated into two-dimensional（2D） layered transition metal oxides and chalcogens（TMOCs）, which can engineer its electronic structure at the atomic scale and tune its intrinsic physical and chemical properties（i.e. carrier concentration and mobility, magnetic, optical, and other properties）. Such intercalations provide a facile way to create new types of multifunctional materials, thus largely extend 2D material＇s applications for opto-electronic devices, energy storage and conversion, photoelectrocatalysis, etc. Recently, many efforts have been focused on seeking suitable synthesis routes to achieve different types of intercalated nanomaterials. Here, we concisely reviewed the recent development on TMOC-based intercalations produced by various intercalated agents in-situ intercalating. The synthetic strategy of alkali metal and non-alkali metal intercalation, polymer intercalation, small organic molecules intercalation and reduced graphene oxide intercalation were mainly reviewed. Through affecting the interlayer interactions and the crystal anisotropy can realize the strategy of in-situ intercalated layered materials.
