3D-printed photo-spectroelectrochemical devices forin situandin operandoX-ray absorption spectroscopy investigation

What is it about?

Three-dimensional printed multi-purpose electrochemical devices for X-ray absorption spectroscopy are presented in this paper. The aim of this work is to show how three-dimensional printing can be a strategy for the creation of electrochemical cells for in situ and in operando experiments by means of synchrotron radiation. As a case study, the description of two cells which have been employed in experiments on photoanodes for photoelectrochemical water splitting are presented. The main advantages of these electrochemical devices are associated with their compactness and with the precision of the three-dimensional printing systems which allows details to be obtained that would otherwise be difficult. Thanks to these systems it was possible to combine synchrotron-based methods with complementary techniques in order to study the mechanism of the photoelectrocatalytic process.

Why is it important?

3D printing is an easy way of building complex objects. We have demonstrated that it can be successfully employed in building cells for complex operando experiments at synchrotron radiation sources. As such, this approach can be easily extended to other and more complex pieces of instrumentation.
