Abstract
In this study, a simple and environmentally friendly method was developed for synthesizing 3D porous cellulose supported palladium nanoparticles (PdNPs) catalysts. PdNPs (3.1 ± 1.4 nm) can be synthesized directly by cellulose solution through microwave heating (60 °C, 4 h) and prepared into microspheres by freeze-drying to degrade methylene blue (MB) and Congo red (CR) rapidly. In addition, the reduction ability of cellulose hydroxyl group was proved by XPS and FTIR results. And the contact angle of 38.20° proves its hydrophilic ability. Cellulose-PdNPs microspheres showed high catalytic efficiency achieved 99 % and after multiple cycles it was still higher than 90 %. Therefore, the method proposed in this paper provides some new applications for cellulose, and the cellulose-Pd catalysts prepared by the research also have potential application value in the field of environment.
