Porous carbon fibres(PCF) was extensively applied to energy storage, environment pollution control and healthcare due to their superior electrical conductivity, diverse aperture,high specific surface area and super electrochemical stability.This paper reviewed the methods of preparing porous carbon fibres.The preparing PCF technology mainly included template methods( hard templates,soft templates, dual-templates), electrospinning technology and polymer blend technology. The working principles of different pore-forming techniques were summarized.The contributions of different preparation techniques to improve material properties such as electrochemical properties,adsorption performance,drug sustained-release materials and catalitic activity in practical applications were described.The different preparation methods had their superiorities and places needed improving.It was proposed that develop more advanced template methods to prepare PCF with reasonable cost, zero environmental pollution, high efficiency and easy removal.
