Herein, a phosphorus-doped MoO2 nanorods-supported Pt catalyst was proposed which exhibited remarkably enhanced catalytic performance toward MOR in comparison with Pt/MoO2 and commercial Pt/C. Specifically, the Pt/MoO2-P possessed the highest peak current density of 62.63 mA cm−2, about 1.38 and 2.21 times higher than that of Pt/MoO2 (45.24 mA cm−2) and Pt/C (28.40 mA cm−2), respectively. Meanwhile, the Pt/MoO2-P possessed high intrinsic activity expressed by specific activity and mass activity, and largely improved catalytic kinetics. Moreover, the chronoamperometry and CO-stripping testing successfully revealed the superior stability and CO-poisoning resistance of Pt/MoO2-P, rendering Pt/MoO2-P a promising catalyst for MOR. The theoretical calculation revealed the electron redistribution and strong metal-support interaction among Pt/MoO2-P catalysts. The greatly enhanced catalytic performance could be attributed to the heteroatom doping engineering, greatly enhancing the conductivity, and inducing electron redistribution, thereby leading to the strong metal-support interaction and high CO-anti poisoning ability.","PeriodicalId":142,"journal":{"name":"ChemElectroChem","volume":"11 24","pages":""},"PeriodicalIF":3.5,"publicationDate":"2024-11-07","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://onlinelibrary.wiley.com/doi/epdf/10.1002/celc.202400505","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143113038","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":4,"RegionCategory":"化学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"OA","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

However, the lack of a penetrating liquid electrolyte requires a much different approach to the design of cathodes. The solid catholyte must enable good Li+ conduction, form good interfaces with active material particles, and have the strength to bind the cathode together during repeated volume changes. Catholyte formulation is often simply adapted from Li-ion design principles, adding a Li salt to the PVDF binder. Here we show that such a PVDF binder at 10 wt % loading is a starved catholyte condition that compromises cell performance. By substituting a 70 : 30 blend of PVDF:PEO, performance is improved while maintaining nearly the same areal loading of LFP active material. Increasing the catholyte fraction to 16 % can also improve performance, but in this case the benefit of including PEO is lessened, with PVDF alone being an adequate catholyte. EIS analysis shows that PEO helps to form charge transfer interfaces at 10 % catholyte, but that its inclusion can degrade interfaces when there is ample catholyte at 16 %. It is also shown that catholyte agglomeration can impede bulk Li conduction, indicating that microstructural factors are of critical importance.","PeriodicalId":142,"journal":{"name":"ChemElectroChem","volume":"11 22","pages":""},"PeriodicalIF":3.5,"publicationDate":"2024-10-30","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://onlinelibrary.wiley.com/doi/epdf/10.1002/celc.202400472","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"142674384","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":4,"RegionCategory":"化学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"OA","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

This often restricts efficiency and product selectivity, since requirements may deviate for electrochemical (catalyst activation) and chemical (organic synthesis) steps, as well as for paired anode- and cathode reactions. Breaking this barrier, we report ex situ electro-organic synthesis as a versatile method that enables unique product selectivity and unusual product pairs. We exemplify the concept for pairing H2 evolution (HER) with anodic alcohol oxidation. The two-step method accomplishes this by separating cathode reactions from organic substrate oxidation, and anodic electrocatalyst activation from chemical conversion of organic substrates in time and space. First, the electro-oxidation of Ni(OH)2 anodes to NiOOH is paired with H2 production by alkaline water electrolysis. Then, “charged” NiOOH electrodes are removed from the electrolyzer and used in external vessels to oxidize model substrate benzyl alcohol under regeneration of Ni(OH)2. Free choice of reaction media outside the electrolyzer allows to selectively obtain benzoic acid (in water) or benzaldehyde (in n-hexane), whereas classic in situ electrosynthesis only produces the acid together with H2. Perspectively, the method enables electrosynthesis of previously inaccessible products paired to H2 generation.","PeriodicalId":142,"journal":{"name":"ChemElectroChem","volume":"11 22","pages":""},"PeriodicalIF":3.5,"publicationDate":"2024-10-30","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://onlinelibrary.wiley.com/doi/epdf/10.1002/celc.202400489","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"142674383","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":4,"RegionCategory":"化学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"OA","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

This work advances the 2,7-AQDS/ferrocyanide flow battery with an ammonium sulphate supporting electrolyte (pH 5) by studying the suitability of six commercially available cation exchange membranes: E-620, NR-212, FS-930, F-1075-PK, F-1850 and N-115. Cell cycling under galvanostatic regime plus potential hold was performed to determine coulombic efficiency, energy efficiency and accessible capacity for each membrane as well as capacity fade rate for three selected membranes under extended operation. Cell cycling under galvanostatic control only was carried out to observe transient membrane behavior alongside accessible capacity and apparent capacity fade rate. It was found that the capacity set by the limiting negolyte is consistent with 1.5 electrons per 2,7-AQDS molecule and that energy efficiency shows a simple direct relationship to membrane thickness, with one exception. Meanwhile, four membranes displayed similar apparent capacity fade rates at this laboratory scale irrespective of their thickness, with capacity loss explained in terms of crossover. The best overall performance was attained by the thinnest membranes, E-620 and NR-212.","PeriodicalId":142,"journal":{"name":"ChemElectroChem","volume":"11 22","pages":""},"PeriodicalIF":3.5,"publicationDate":"2024-10-30","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://onlinelibrary.wiley.com/doi/epdf/10.1002/celc.202400516","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"142674382","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":4,"RegionCategory":"化学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"OA","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

V-based layer-like oxides are promising candidates as cathode materials for ZIBs; however, they face challenges such as low electrical conductivity, poor cycling stability, and limited Zn2+ storage capacity. In this study, Li-V3O7 ⋅ H2O electrode materials were successfully synthesized using a hydrothermal method. The doping of lithium ions has led to a significant expansion of the interlayer spacing within the electrode structure, which enhances ion mobility and improves ion transport speed as well as charge-discharge rates. Additionally, the increased spacing allows for the accommodation of more zinc ions, resulting in greater specific capacity and energy storage. More importantly, this modification reduces structural strain, minimizes the dissolution of vanadium-based materials, and maintains electrode integrity over multiple cycles, thereby improving cycling stability. Consequently, the properties of V3O7 ⋅ H2O electrodes were substantially enhanced through lithium-ion doping. The Li-V3O7 ⋅ H2O cathode has a specific capacity of 411.8 mAh g−1 at low current and maintains 83 % of its capacity at 4.0 A g−1 for 4800 cycles, indicating a noteworthy improvement over pristine V3O7 ⋅ H2O.

The reactivity of single-atom catalysts (SACs) is typically modeled with first principles approaches taking insight from heterogenous catalysis. An increasing number of studies show that the chemistry of SACs is more complex than often assumed, and shares many aspects in common with coordination chemistry. This evidence raises challenges for computational electrocatalysis of SACs. In this perspective we highlight a few fundamental ingredients that one need to consider to provide reliable predictions on the reactivity of SACs for electrochemical applications. We discuss the role of the local coordination of the metal active phase, the need to use self-interaction corrected functionals, in particular when systems have magnetic ground states. We highlight the formation of unconventional intermediates with respect to classical metal electrodes, the need to include the stability of SACs in electrochemical conditions and the role of solvation in the analysis of new potential catalytic systems. This brief account can be considered as a tutorial underlining the importance of treating the reactivity of SACs. In fact, neglecting some of these aspects could lead to unreliable predictions failing in the design of new electrocatalysts.","PeriodicalId":142,"journal":{"name":"ChemElectroChem","volume":"11 22","pages":""},"PeriodicalIF":3.5,"publicationDate":"2024-10-29","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://onlinelibrary.wiley.com/doi/epdf/10.1002/celc.202400476","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"142674107","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":4,"RegionCategory":"化学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"OA","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
