In the field of photocatalysis, various semiconductor materials have been widely used, precisely because of their electronic structure, which allows them to operate under the different types of irradiations. Titanium dioxide, TiO2, is the most widely used photocatalyst due to its biological and chemical inertness, non-toxicity, availability and affordability. Nevertheless, the inefficient utilization of visible light and high recombination rate of electrons and holes, limit its practicalapplication. Two types of modifications have been used to improve certain properties of TiO2andtake the advantages of the good ones: changing the phase structure, crystallinity, or morphology and combining with various ions, noble metals, semiconductors or other materials by doping, deposition, or sensitization [1,2]. In this work, sol-gel synthesized TiO2 [3] was modified by depositing carbon quantum dots (CQD) and/or cadmium sulfide, CdS, in order to form heterojunctions and so-called"Z" scheme [4]. C...QDs were deposited by decomposition of citric acid in hydrothermal conditions (sample CQD-TiO2), and CdS by thermal decomposition of thiourea in the presence of cadmium acetate (samples CQD-TiO2 and CQD-TiO2-CdS). ...
