Over the past decades,there have been many synthesis methods on producing well-defined crystals,due to their enormous application potentials in industrial field.Among them,high temperature gas-phase reactions(HTGR)approach may be one of the most promising processes for fabrication of well-defined crystals with controllable structure,size,shape,and composition.This review is focused on the recent progresses in synthesizing well-defined crystalline TiO2dominated with,respectively,{001}facets and{105}facets,one-dimensional ZnO and SnO2nanorods/nanowires,MoS2nanosheets as well as GaP,InP,and GaAs nanowires via HTGR approach.Although these research works were currently carried out on experimental scale,it is worth to note that the industrial importance of this HTGR approach for design and fabrication of well-defined crystals in the future owing to its advantages of continuous and scalable production with controlled dimensions and low cost.
