WaPoDe employs surface-to-bulk (S-to-B) defects ratio to improve selectivity, sensitivity and response time of ZnO-based nanoparticles as ECS for Diclofenac, Tetracycline, Doxorubicin, Fluoxetine and Chlorpyrifos. We use XRD, SEM, TEM, BET, Raman, FTIR, XPS, UV-Vis DRS and PL spectroscopy to study properties of synthetized ZnO-based nanoparticles. A variety of electrochemical techniques are applied to test the electrochemical activity of modified electrodes. One of the goals is to correlate S-to-B defects ratio in the nanoparticles with their electrochemical activity. Theoretical modeling us used to comprehend the mechanism of pollutants molecule interaction with materials surfaces allowing further improvement of response time.

WaPoDe will have impact on:

• transformation of local economy by promoting new technologies through communication, dissemination and implementation of our results,
• building human capacity for the high-tech companies by training young researchers, and
• increasing environmental awareness in society.
