MoS2 ile dekore edilmiş TiO2 Nanotüp Elektrotların Sentezi, Karakterizasyonu ve Fotoelektrokimyasal Özellikleri

Bu araştırmada, TiO2/MoS2 nanokompozit elektrotlar fotoelektrokimyasal performanslarını araştırmak için sentezlenmiştir. İlk olarak, Ti folyo üzerinde anodik oksidasyonla TiO2 nanotüp dizileri üretilmiştir. Daha sonra; MoS2 nano yapıları, TiO2 nanotüpler üzerinde hidrotermal yöntemle sentezlenmiştir. Hazırlanan nanokompozit elektrotlar, X-Ray kırınımı (XRD) ve alan emisyonu taramalı elektron mikroskobu (FESEM) kullanılarak karakterize edilmiştir. Geçici foto-akım tepkisi, elektrotların fotoelektrokimyasal aktivitesini araştırmak için analiz edilmiştir. Elde edilen sonuçlar, TiO2 nanotüp dizileri etrafına MoS2 nanoyapılar ile homojen bir şekilde kaplandığı belirlenmiştir. Ayrıca, TiO2/MoS2 yapıların TiO2 elektrota göre daha iyi fotoelektrokimyal aktivite gösterdiği belirlenmiştir.

Synthesis, Characterization and Photoelectrochemical Properties of MoS2 decorated TiO2 Nanotubes Electrodes

In this research, TiO2/MoS2 nanocomposite electrodes were synthesized to investigate the photoelectrochemical performances. Firstly, TiO2 nanotubes were fabricated by anodic oxidation on Ti foil. Then, MoS2 nanostructures were synthesis by hydrothermal method on TiO2 nanotubes. The prepared nanocomposite films were characterized by using X-Ray diffraction (XRD) and field emission scanning electron microscopy (FESEM). The transient photocurrent response was analyzed to investigate photoelectrochemical activity of electrodes. The results show that TiO2 nanotube arrays coated with MoS2 nanostructure homogeneously. Furthermore, TiO2/MoS2 nanocomposite electrode were shown better photoelectrochemical activity then bare TiO2 electrode.
