3866 | 680 | Mn3O4 nanozyme coating accelerates nitrate reduction and decreases N2O emission during photoelectrotrophic denitrification by Thiobacillus denitrificans-CdS | https://doi.org/10.1021/acs.est.0c02709 | Metal oxide | This work successfully constructed a Mn3O4 nanozyme-coated biosemiconductor, Thiobacillus denitrificans-cadmium sulfide (T. denitrificans-CdS@Mn3O4), via a simple, fast, and economic method. After Mn3O4 coating, the ROS were greatly eliminated; the concentrations of hydroxyl radicals, superoxide radicals, and hydrogen peroxide were reduced by 90%, 77.6%, and 26%, respectively, during photoelectrotrophic denitrification (PEDeN). T. denitrificans-CdS@Mn3O4 showed a 28% higher rate of nitrate reduction and 78% lower emission of nitrous oxide (at 68 h) than that of T. |

7897 | 680 | Mn3O4 | 10-100 | nm | TEM | The TEM image of the T. denitrificans-CdS@Mn3O4 system also revealed that the particles were distributed on the bacterial cells and that the diameter of those particles ranged from 10 to 100 nm (Figure 2d), similar to that of T. denitrificans-CdS |
