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.

To the Editor:5q spinal muscular atrophy(5qSMA)is an autosomal recessive neuromuscular disorder caused by the lack of the survival motor neuron(SMN)protein encoded by the SMN1 gene,located at 5q11.2-q13.3.[1]The incidence is 1/10,000-1/6000 live births,and the mutation carrier rate in China is 1/42.[1]Spinal muscular atrophy(SMA)is mainly divided into four subtypes:SMA type I,II,III,and IV,based on the motor milestones ever *** I-III occur in children,[1]which often result in progressive muscular atrophy and weakness as well as multi-system dysfunction,including nutritional and metabolic issues.[2]Children with SMA may have hidden nutritional and lipid imbalances,despite normal body appearance and anthropometric measurements,making it difcult to detect early and intervene.
