Description
Summary:In this conceptual review, we present the optical and electronic characteristics of quantum dots for the designing of organic synthesis experiments through the photocatalysis. We discuss the control parameters associated to the charge recombination processes on the semiconductor interface. The positioning of bands and control of intragap states, such as charge donors and acceptors, can define the performance of faradaic processes. Electrochemical strategies, such as voltammetry, can be used as a powerful tool for the determining of the electronic band edges with good precision. Quantum dots are the investigative focus of many research groups due to the quantum confinement effect observed. Thus, the photocatalysis has emerging as an important research branch applied to organic synthesis. In this article, the properties and concepts of these semiconductor nanocrystals are related and discussed for a better understanding and guidance to catalysis applications.
