Nevertheless, the latter is highly demanding in efficient mass-production of hydrogen. A SiO2 nanospheres template-synthesis is used to prepare mesoporous molybdenum carbide nanocrystals-embedded nitrogen-doped carbon foams (mp-Mo2C/NC). The material shows much more excellent catalytic activity than the non-etched Mo2C/NC toward hydrogen evolution reaction (HER) in acidic medium. More interestingly mp-Mo2C/NC still has larger overpotential than Pt/C at lower current densities, but possess remarkably smaller overpotential than the latter at higher current densities for much better electrocatalytic performance. An approach is developed to investigate the electrode kinetics by Tafel plots, especially with eliminating the diffusion effect, indicating that Pt/C and mp-Mo2C/NC display different reaction mechanisms. At low current densities the former presents reversible reaction, while the latter shows mixed electrochemical polarization/reversible electrode process. In the region of higher current densities, the former becomes totally gas-diffusion controlled with large overpotential, while the latter can still retain an electrode polarization process for much lower overpotential at the same current density. Result endorses that the meso-porously structured mp-Mo2C/NC plays a critical role in avoiding gas diffusion control-resulting large overpotential at high current densities. This work holds great potential for an inexpensive catalyst better than Pt/C in practical applications of mass-production hydrogen at high current densities, while clearly shedding fundamental lights on designs of rational HER catalysts for the uses at high current densities.</div>","PeriodicalId":61638,"journal":{"name":"材料导报:能源(英文)","volume":"3 3","pages":"Article 100215"},"PeriodicalIF":0.0,"publicationDate":"2023-08-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"43506331","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

In the current work, we have optimised Sn loading on Cu gas diffusion electrodes (GDEs) by electrochemical spontaneous precipitation. Samples with various Sn loadings were tested in a three-chamber GDE reactor to evaluate their CO2 reduction performances. The best performance of 92% CO Faradaic efficiency at a cathodic current density of 120 mA cm−2 was obtained from the 20 min Sn deposited Cu2O sample operated at −1.13 V vs. RHE. The electrocatalyst had ∼13% surface coverage of Sn on Cu GDE surface, and had Sn in oxide form and copper in metallic form. The catalyst also showed stable performance and was operable for >3 h under chronoamperometric conditions. The surface of the GDE reduces from Cu2O to Cu during eCO2R and goes further reconstruction during the eCO2R.
