The invention discloses a pAg-SiO2f one-dimensional porous composite material as well as a preparation method and application thereof, and belongs to the technical field of electrochemical functional materials. The composite material sequentially comprises a framework layer, a metal silver layer, a SiO2-based fiber layer and a metal silver layer from inside to outside, the preparation method comprises the following steps: taking a skeleton layer as a collection template, carrying out electrostatic spinning to obtain thermoplastic elastic fibers, sequentially dipping the thermoplastic elastic fibers in a silver ion solution and a reducing agent solution, then taking the thermoplastic elastic fibers as the collection template, carrying out electrostatic spinning on spinnable precursor sol containing a silicon source, coating PVA, and carrying out electrostatic spinning to collect the thermoplastic elastic fibers, so as to obtain the composite material. Then sequentially dipping in a silver ion solution and a re
