a Schematic illustration of the microbial vulcanization of ZIF-67 to synthesize MV-S/Co(OH)2/MI. b SEM image of microbial cells and MV-S/Co(OH)2/MI. c PXRD monitoring of ZIF-67 by microbial vulcanization under different times. d SEM and sample photos of the transitions from ZIF-67 to MV-S/Co(OH)2/MI using different vulcanizing time (the scale bars are 400 nm). e Double aberration-corrected HAADF-STEM image (inset: metal arrays of Co(OH)2 lattice), f AFM (inset: thickness profile), and g elemental mapping images of MV-S/Co(OH)2/MI. h Photograph of MV-S/Co(OH)2/MI laboratory preparation process. i The MV-S/Co(OH)2/MI obtained by one lab-scale preparation. j Plates (LMEC represents Lab of Molecule-based Energy Chemistry) marked with bacteria after vulcanization of ZIF-67.
