Diagram of self-catalyzed and saturated VLS crystal growth mechanism for ZnO nanowire synthesis in the miniature quartz tube reactor. ZnO/C undergo a carbothermal reduction a reaction at high temperature to produce Zn+ZnO x +CO vapors. These vapors are transported downstream and condense on the FTO glass substrate to form liquid Zn droplets (b) and ZnO nanoparticles (c). Further reaction time results in (d) adsorption and nucleation ZnO nanowires
