$MoS_2$ ile dekore edilmiş $TiO_2$ Nanotüp Elektrotların Sentezi, Karakterizasyonu ve Fotoelektrokimyasal Özellikleri

Bu araştırmada, $TiO_2$/$MoS_2$ nanokompozit elektrotlar fotoelektrokimyasal performanslarını araştırmak için sentezlenmiştir. İlk olarak, Ti folyo üzerinde anodik oksidasyonla $TiO_2$ nanotüp dizileri üretilmiştir. Daha sonra; $MoS_2$ nano yapıları, $TiO_2$ 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, $TiO_2$ nanotüp dizileri etrafına $MoS_2$ nanoyapılar ile homojen bir şekilde kaplandığı belirlenmiştir. Ayrıca, $TiO_2$/$MoS_2$ yapıların $TiO_2$ elektrota göre daha iyi fotoelektrokimyal aktivite gösterdiği belirlenmiştir.

Synthesis, Characterization and Photoelectrochemical Properties of $MoS_2$ decorated $TiO_2$ Nanotubes Electrodes

In this research, $TiO_2$/$MoS_2$nanocomposite electrodes were synthesized to investigate the photoelectrochemical performances. Firstly, $TiO_2$ nanotubes were fabricated by anodic oxidation on Ti foil. Then, $MoS_2$ nanostructures were synthesis by hydrothermal method on $TiO_2$ 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 $MoS_2$ nanostructure homogeneously. Furthermore, $TiO_2$/$MoS_2$ nanocomposite electrode were shown better photoelectrochemical activity then bare $TiO_2$ electrode.
