Smart electrocatalysts are synthesized from chitosan polymer and magnetic particles to enhance power by plant based sediment microbial fuel cell (P-SMFC). Cross-linked procedure is performed gelatinous microspheres as supporting metals (Cu, Pd, Mn, Pt, and Ni) and magnetic particles which create a porous structure on smart catalysts for increase ORR activity. A high and quick OCV rising is achieved with addition of Mag-Pd-Ch in reactor, and OCV value immediately increase from 0.408 V to 0.819 V within 10 minutes. The highest power density is also obtained as 1298 mW m-2 for reactor with Mag-Pd-Ch, which was 15 times higher than control. Significant metal leaching is observed using plant growth for smart catalyst containing Cu. Consequently, high power production, good stabilization, easy separation from water environment due to magnetic property, and relatively low cost make use of Mag-Pd-Ch both economic and environment friendly tools to enhance power generation in P-SMFC.

新型基于壳聚糖的智能阴极电催化剂，可用于植物基沉积微生物燃料电池中的高发电。

由壳聚糖聚合物和磁性颗粒合成智能电催化剂，可通过植物基沉积物微生物燃料电池（P-SMFC）增强功率。进行交联的过程是凝胶状微球体，作为支撑金属（Cu，Pd，Mn，Pt和Ni）和磁性颗粒，它们在智能催化剂上形成多孔结构以提高ORR活性。通过在反应器中添加Mag-Pd-Ch，可实现OCV的快速快速上升，并且OCV值在10分钟内立即从0.408 V上升至0.819V。对于具有Mag-Pd-Ch的反应堆，最高功率密度为1298 mW m-2，比对照高15倍。使用植物生长的含铜智能催化剂可观察到大量金属浸出。因此，由于具有磁性，因此产生的功率高，稳定性好，易于与水环境分离，
