Particulate matter which has aerodynamic diameter less than 2.5 µm (PM2.5) has seriously impacted on human health such as cardio-respiratory diseases. Graphene foam is a 3-dimensional graphene, in which carbon atoms are arranged into a honeycomb lattice. In this study, PM2.5 capture using graphene foam filter is demonstrated. The graphene foam is synthesized by chemical vapor deposition using nickel foam and palm oil as a template and carbon source, respectively. After that the sample is soaked with FeCl3 to dissolve the nickel foam template. The presence of graphene on nickel foam is confirmed by Raman spectroscopy. The morphologies of graphene and PM2.5 particles are measured by field emission scanning electron microscope. The element composition of PM2.5 is investigated by energy-dispersive X-ray spectroscopy (EDX). The results show that graphene foam can capture various types of PM2.5 particles (such as aluminium, silicon, phosphorus and so on) without additional energy.
