A protocol aiming at making use of the huge amount of naturally existing wastes such as defoliation, pericarp and egg shell for nanostructured composite materials was proposed. In this study, a green synthetic route using naturally existing membrane as support was developed for the synthesis of nanostructured and porous metal- or metal oxide-carbon composite films. Different metallic ions (Co2+, Ni2+, Fe3+, Mn2+ or Cu2+) can be easily adsorbed onto egg membranes and the followed calcination process results in the formation of Co/C, Ni/C, Fe3O4/C, MnO/C or Cu/Cu2O/CuO/C composite films. The electrochemical studies demonstrate that such composite films would have potential applications in energy fields. This method would provide a general green concept for chemical synthesis and be beneficial to the global sustainable future.
