With the current development of nanotechnology field, many different high-quality with cost-effective nanomaterials have come into use in various applications. However, the needs for renewable resources-based nanomaterials are inevitable and increasing gradually in the last few years. Therefore, the scientists attempt to use the renewable resources as the feedstocks for the development of their desired products. The current special issue “Current advances in green nanomaterials applications” presents to readers the articles covering different aspects of the synthesis, characterizations and applications of the renewable resources-based nanomaterials.

Herein, we reported a method to prepare magnetic sodalite sphere by using the mud from backwash wastewater after polyaluminum chloride (PAC) coagulation. The results showed that approximately 100% of Fe in the wastewater was precipitated as flocculent iron mud (FM) by adding PAC. FM was converted to spherical magnetic sodalite (FMP) with a diameter of 3 μm via a facile alkali hydrothermal method without adding Al/Si resources or reductant. The product FMP had the saturated magnetization of 10.9 emu g−1 and high Zn2+ adsorption capacity of 50.6 mg g−1. Without coagulation with PAC, the removal rate of Fe from the… More >
