Effect of ZnO-Loading Method on Adsorption and Decomposition Capacities of Expanded Graphite/ZnO Composites for Crude Oil

Abstract:

Three expanded graphite/ZnO composites, marked as EG/ZnO-1, EG/ZnO-2 and EG/ZnO-3, were prepared by heating a mixture of zinc acetate and water-washed expandable graphite, dried expandable graphite and EG, respectively. The adsorption capacity of the composites for spilled crude oil was measured, and under UV irradiation, the decomposition of the absorbed crude oil was investigated by oil weight loss method. The results show that the composites have adsorption and photocatalysis capacity for crude oil at the same time, and the adsorption and photocatalysis capacity are influenced by ZnO-loading method.
