What is it about?
We developed a 3D printed operando cell that allowed us to perform photodeposition of Pd on TiO2 and control this process by XANES and EXAFS spectroscopies. At the same time, we showed that the geometry of the cell allowed achieving much better size distribution of Pd nanoparticles compared to standard laboratory synthesis procedure.

Why is it important?
Development of in situ and operando methodologies is important for better understanding of the structural parameters in functional materials (e.g. catalysts) and their effect on the materials' properties. The cell and the method that we proposed can be used to study a big variety of photoactive materials, especially metal-promoted photocatalysts.
Perspectives
We hope one can you the simple cell design in future studies, and also take advantage of the insights about formation of Pd nanoparticles on TiO2 that we presented.
