Highly porous 1D nanostructures with controlled size, morphology and high conductivity are beneficial for a number of applications, including highly efficient gas sensors and batteries. Here, we have synthesized composite metal/metal oxide graphene-based nanofibers from an electrospun polymer-metal precursor. Upon heat treatment, metal species diffuse throughout the polymer matrix, nucleate as metal nanoparticles, and subsequently catalyze the formation of crystalline carbon. In this study, we investigate the role of polymer matrix and annealing conditions on metal diffusion, clustering, and growth as well as the subsequent evolution of crystalline carbon. We utilize these parameters to control the size and surface area of metal and metal oxide nanostructures that allow us to tune our material for gas sensing applications. Investigation of the particle growth of these nanostructures within polymer matrix will provide insight to the controlled synthesis and assembly of the nanoparticle constituents and their effect on gas sensing sensitivity.
