- •
In the photodeposition of CdSe on TiO2 (CdSe/TiO2), the addition of mercaptoacetic acid (MAA) decreases the particle size.
- •
The MAA addition decreases the contact angle of CdSe particle against the TiO2 surface.
- •
The MAA addition significantly increases the TiO2-surface coverage by CdSe.
- •
The performance of photoelectrochemical cells using CdSe/TiO2 as the photoanode was evaluated under simulated sunlight.
- •
The use of the CdSe/TiO2 photoanode prepared by adding MAA greatly enhances the generation of H2 from water.
