The synthesis and characterization of catalysts, namely Ni-Co-Cd/CNFs, with a metal fixed ratio of 20 % wt. for DAFC applications are the main goals of this work. Two different catalyst concentrations were prepared with fixed nickel concentrations (Ni₁₂Co₆Cd₂ &amp; Ni₁₂Co₄Cd₄). This research represents the first preparation of ternary Ni-Co-Cd/CNF for DAFC applications. Various methods, including electrochemical tests, transmission electron microscopy, scanning electron microscopy, and x-ray diffraction, are used to characterize the catalysts. Scanning electron microscopy (SEM) revealed that the fabricated sample exhibited a good nanofiber form and a distinct nanoparticle look. The samples' capacity for alcohol electrocatalysis was assessed using cyclic voltammetry, impedance spectroscopy, chronoamperometry, scan rate, and response time. The oxidation peak current density and electrode stability both rise when the concentration of Cd in Ni-Co-Cd/CNF increases. The oxidation peak current density of Ni₁₂Co₄Cd₄ at the optimum ethanol concentration (1 M ethanol in 1 M KOH) is found to be 29.7 mA/cm². While the maximum current density is found to equal 38.86 mA/cm². In addition, the CV results yield the oxidation peak current density to be 3.5 mA/cm² at the optimum methanol concentration (1 M methanol in 1 M KOH). Ni₁₂Co₄Cd₄ exhibits promoted electrochemical properties to ethanol electrooxidation rather than methanol oxidation. Furthermore, these findings are enhanced by the highly calculated diffusion coefficient of Ni₁₂Co₄Cd₄ towards ethanol in comparison with methanol (2.30 × 10⁻⁶ cm²/s for ethanol and 3.07 × 10⁻⁷ cm²/s for methanol). This work has demonstrated how to use a unique technique to develop an efficient alcohol electrooxidation catalyst based on nickel, cobalt, and cadmium nanoparticles.</div></div>","PeriodicalId":431,"journal":{"name":"Solid State Ionics","volume":"423 ","pages":"Article 116846"},"PeriodicalIF":3.0,"publicationDate":"2025-03-19","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143642963","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":4,"RegionCategory":"材料科学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

This review provides a comprehensive analysis of dopant-driven modifications in Li₇P₃S₁₁, emphasizing their impact on structural evolution, ionic transport, electrochemical performance, and long-term stability. Both cationic (e.g., transition and alkali metals) and anionic (e.g., oxygen) doping strategies are examined, offering insights into their roles in optimizing ionic conductivity and interfacial compatibility. Sulfide dopants enhance lithium-ion mobility and interfacial stability with lithium metal and sulfur cathodes, while oxide dopants improve air stability and suppress dendrite formation. Nitride dopants, though beneficial for interfacial compatibility, may introduce additional resistance at electrode-electrolyte interfaces. Despite these advancements, challenges such as dopant-induced phase instability, synthesis complexity, and environmental sensitivity persist, necessitating a strategic approach to doping. By categorizing dopants based on their chemical interactions with the Li₇P₃S₁₁ matrix, this review outlines a framework for rational dopant selection and design.
