To seek suitable electrode materials with excellent NH₄⁺-storage is still in the exploratory stage and full of challenge. Herein, an inorganic-polymer hybrid, poly(3,4-ethylenedioxithiophene) (PEDOT) intercalated hydrated vanadium oxide (VOH), named as VOH/PEDOT, is developed to tune the structure of VOH for boosting NH₄⁺ storage. By the intercalation of PEDOT, the interlayer space of VOH is increased from 11.5 Å to 14.2 Å, which notably facilitates the rapid transport of electrons and charges between layers and improves the electrochemical properties for NH₄⁺ storage. The achieved performances are much better than progressive NH₄⁺ hosting materials. In addition, the concentration of polyvinyl alcohol/ammonium chloride (PVA/NH₄Cl) electrolyte exerts a great impact on the NH₄⁺ storage in VOH/PEDOT. The VOH/PEDOT electrode delivers specific capacitance of 327 F g⁻¹ in 1 M PVA/NH₄Cl electrolyte at −0.2–1 V. Furthermore, the quasi-solid-state VOH/PEDOT//active carbon hybrid supercapacitor (QSS VOH/PEDOT//AC HSC) device is assembled for NH₄⁺ storage, and it exhibits the capacitance of 328 mF cm⁻² at 1 mA cm⁻². The energy density of QSS VOH/PEDOT//AC NH₄⁺-HSC can reach 2.9 Wh m⁻² (2.6 mWh cm⁻³, 10.4 Wh kg⁻¹) at 1 W m⁻² (0.9 mWh cm⁻³, 35.7 W kg⁻¹). This work not only proves that the PEDOT intercalation can boost the NH₄⁺ storage capacity of vanadium oxides, but also provides a novel direction for the development of NH₄⁺ storage materials.</p></div>","PeriodicalId":100036,"journal":{"name":"Advanced Sensor and Energy Materials","volume":"1 2","pages":"Article 100013"},"PeriodicalIF":0.0,"publicationDate":"2022-06-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://www.sciencedirect.com/science/article/pii/S2773045X22000139/pdfft?md5=663b8c1d68b3510600fd1c4a5cbbd915&pid=1-s2.0-S2773045X22000139-main.pdf","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"88342236","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"OA","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

In line with the distinctive catalytic nature of Pd to reversibly drive both FAOR and CO₂RR, we first illustrate the intimate mechanistic relation between these two reversed reactions over Pd surfaces. Next, recent advances in developing Pd-based bifunctional catalysts and relevant optimization strategies are briefly summarized, including geometric structure engineering with preferential facet exposure, construction of crystallographic ordering intermetallic, electronic structure manipulation through metal or metalloid doping to fine tune the binding strength for active and poisoning intermediates.
