Abstract
In this study, HPP-RGO aerogels, which were based on a hydrothermal pomelo peel (HPP) and reduced graphene oxide (RGO), were fabricated by using a green and eco-friendly two-step hydrothermal method. The characterization results showed that the HPP-RGO aerogel was endowed with extremely low density, high specific area, robust thermal stability, good mechanical property, stable acid–alkali resistance, superior recyclability, and excellent hydrophobicity and lipophilicity. Remarkably, the typical 40%-HPP-RGO aerogel presented a preferable adsorption capacity (45–80 g·g–1). Moreover, continuous water/oil separation was achieved via the water ring vacuum pump. The successful preparation of the HPP-RGO aerogel endows the pomelo peel with high value-added properties and improves the comprehensive utilization of agricultural wastes. Furthermore, it would open up bright prospects for the field of oil adsorption and water/oil separation.Keywords
