Comparing defect-assisted interfacial charge transfer in CdS/PSA and CdS/TiO2NTAs nanoheterojunctions for enhanced photodegradation and biosensing

Comparing defect-assisted interfacial charge transfer in CdS/PSA and CdS/TiO2NTAs nanoheterojunctions for enhanced photodegradation and biosensing

Firstly, oxygen vacancy defects are intentionally introduced in the preparation process of TiO2 nanotube arrays (TiO2-NTAs) and porous silicon arrays (PSA) films through the anodic oxidation method after annealing treatment, as expected. Then, CdS/TiO2-NTAs and CdS/PSA heterostructures are successfu...
