The discovery of efficient,selective,and stable electrocatalysts can be a key point to produce the largescale chemical fuels via electrochemical CO_(2) reduction(ECR).In this study,an earth-abundant and nontoxic ZnO-based electrocatalyst was developed for use in gas-diffusion electrodes(GDE),and the effect of nitrogen(N)doping on the ECR activity of ZnO electrocatalysts was ***,a ZnO nanosheet was prepared via the hydrothermal method,and nitridation was performed at different times to control the N-doping *** an increase in the N-doping content,the morphological properties of the nanosheet changed significantly,namely,the 2D nanosheets transformed into irregularly shaped ***,the ECR performance of Zn O electrocatalysts with different N-doping content was assessed in 1.0 M KHCO_(3) electrolyte using a gas-diffusion electrode-based ECR *** the ECR activity increased after a small amount of N doping,it decreased for higher N doping *** them,the N:ZnO-1 h electrocatalysts showed the best CO selectivity,with a faradaic efficiency(FE_(CO))of 92.7%at-0.73 V *** hydrogen electrode(RHE),which was greater than that of an undoped Zn O electrocatalyst(FE_(CO)of 63.4%at-0.78 V_(RHE)).Also,the N:ZnO-1 h electrocatalyst exhibited outstanding durability for 16 h,with a partial current density of-92.1 mA cm^(-2).This improvement of N:ZnO-1 h electrocatalyst can be explained by density functional theory calculations,demonstrating that this improvement of N:ZnO-1 h electrocatalyst comes from(ⅰ)the optimized active sites lowering the free energy barrier for the rate-determining step(RDS),and(ⅱ)the modification of electronic structure enhancing the electron transfer rate by N doping.

Salmonella grows better under aerobic conditions as a facultative anaerobic foodborne pathogenic bacteria. The oxygen-scavenging activity of Lactococcus lactis in the intestinal tract is a promising strategy for preventing Salmonella infection. In this study， the aerobic respiration requirement and preventive mechanism of Lactococcus lactis subsp. lactis (L. lactis) KLDS 4.0325 in murine models infected by Salmonella enterica subsp. enterica serovar Typhimurium (S. Typhimurium) SL1344 were investigated. Results indicate that L. lactis KLDS 4.0325 is capable of aerobic respiratory metabolism in the host intestine when exogenous heme exists， and decrease intestinal oxygen concentration， which in turn trigger autophagy of intestinal cells to reduce S. Typhimurium load， improve gut microbiota composition， alleviate intestinal barrier injury and inflammation response. These results suggest that aerobic respiration L. lactis KLDS 4.0325 can prevent S. Typhimurium infection in a new way in which by restoring intestinal cell hypoxia， maintaining immune balance and regulating intestinal flora.
