Abstract

Halloysit nanotüp (HNTs) temelli, MoS₂ ve Pd içeren nanokompozitler (HNTs@MoS2, HNTs@Pd ve HNTs@Pd–MoS2) hazırlanmış ve süperkapasitör uygulamaları için elektrokimyasal özellikleri değerlendirilmiştir. Sentezlenen malzemelerin yapısal ve morfolojik özellikleri çeşitli karakterizasyon teknikleri ile incelenmiş, HNT’lerin tübüler yapısını korurken MoS₂ ve Pd ile etkin şekilde kaplandığı doğrulanmıştır. 1 M KOH ortamında gerçekleştirilen elektrokimyasal ölçümler, HNTs@Pd–MoS2 nanokompozitinin 1 A g-1 akım yoğunluğunda 553.2 F g-1 kapasite sergileyerek diğer numunelere kıyasla üstün performans gösterdiğini ortaya koymuştur. Ayrıca bu elektrot daha düşük iç direnç ve daha iyi yük taşınım özellikleri sergilemiştir. Döngü kararlılığı açısından değerlendirildiğinde, HNTs@Pd–MoS2 elektrodu 500 çevrim sonunda başlangıç kapasitesinin %93.4’ünü koruyarak uzun dönemli stabil performans göstermiştir. Elde edilen bu sonuçlar, sentezlenen kompozit yapıların yeni nesil enerji depolama uygulamaları için umut verici bir potansiyel sunduğunu göstermektedir.

Halloysite Nanotube-Based Pd–MoS2 Hybrid Electrodes for High-Performance Supercapacitors

Abstract

Halloysite nanotubes (HNTs)-based nanocomposites incorporating MoS2 and Pd (HNTs@MoS2, HNTs@Pd, and HNTs@Pd–MoS2) were prepared and their electrochemical properties were evaluated for supercapacitor applications. Various characterization techniques were used to examine the synthesized materials, demonstrating effective decoration of HNTs with MoS₂ and Pd while retaining their tubular structure. Electrochemical measurements in 1 M KOH revealed that the HNTs@Pd–MoS2 nanocomposite delivered 553.2 F g-1 at 1 A g-1, demonstrating superior performance relative to the other samples. In addition, this electrode showed lower internal resistance and improved charge transport behavior. From the cycling stability perspective, the HNTs@Pd–MoS2 electrode retained 93.4% of its initial capacitance after 500 cycles, indicating stable long-term performance. These findings demonstrate that the HNTs@Pd–MoS₂ hybrid is a promising electrode material for high-performance supercapacitor applications.
