Direct Graphene Growth on Anodic Aluminum Oxide Membrane Using Chemial Vapour Deposition for Solar Evaporator Performance Enhancment

Abstract

In this paper, we have demonstrated additive-free direct CVD graphene growth on anodic alumina oxide (AAO) membranes at lower temperature benchmark (1000oC) for thermal desalination absorber applications. Various film deposition parameters are optimized to obtain the best absorption performance. The absorbance is varying between 95 to 97 % (vs. 20 % for AAO) which leads to maximizing the heat energy absorption in the system leading to more vapor for condensing process.
