Abstract: The analytical tools have given not only chemistry but science as a whole, new horizons when it comes to the comprehension of chemical phenomena. With precise information, new possibilities emerged in the identification and characterization of novel compounds and advances in several areas of chemistry. In this context, spectroelectrochemistry (SEC) combines complementary tools to that the electrochemistry techniques drive the reactions and spectroscopic methods are focused on species analysis. Thus, this strategy provides a way to monitor what is happening in situ or in operando, making it a powerful tool for the identification of intermediates of reaction, mechanistic, kinetic studies, and even quantitative analysis. However, SEC comes with a somewhat inconvenient drawback: even though it has been rising in popularity, setting up the SEC cells might be complicated for newcomers. On the other hand, 3D printing becomes interesting and, at the same time, incredibly effective technology for the user to create customized SEC cells to support any necessity. In this review, we will go over the importance of 3D printing in the design and use of spectroelectrochemical cells Ver menos
