Biosynthesis based on the electrochemically active bacterial reduction capacity is an environmentally friendly method for recycling metal resources and is commonly used to reduce metal ions to nanoparticles. However, these bio-nanoparticles cannot be directly used as a catalyst due to poor conductivity. Recently, Liu et al. solved this problem by hydrothermal reaction, and carried out doping of heteroatoms and alloying of Pd-Cu. Using the protective effect of graphene, they avoid the aggregation of nanoparticles and maintain a porous structure. These measures result in better electrocatalytic activity and stability than Pd/C commercial catalysts. This synthetic approach opens up new ideas for making full use of natural resource design catalysts. (Science Advances DOI: 10.1126/sciadv.1600858)
