<p class="MsoNormal" style="text-align:justify;text-indent:18.0pt"><span lang="EN-GB" style="font-size:11.0pt;font-family:"Arial","sans-serif"">Recent years have witnessed the introduction of spatiotemporal spectroscopy for the characterization of catalytic
solids at previously unattainable resolution and sensitivity. They have revealed that heterogeneous catalysts are more heterogeneous than often expected. Dynamic changes in the nature of active sites, such as their distribution and accessibility, occur both
between and within particles. Scientists now have micro- and nano-spectroscopic methods at hand to improve the understanding of catalyst heterogeneities and exploit them in rational catalyst design. In this lecture the latest developments within this field
are discussed. The trends include detection of single catalyst particles or molecules, super-resolution chemical imaging, the transition from two- to three-dimensional imaging, selective staining, integration of spectroscopy with electron microscopy or scanning
probe methods, and measuring under realistic reaction conditions. Such approaches change the hitherto somewhat static picture of heterogeneous catalysis into one that acknowledges that catalyst materials behave almost like living objects — explaining why many
characterization methods from the life sciences are being incorporated into the field of heterogeneous catalysis research. As a showcase, I present the life and death of a catalytic cracking particle. By combining tools it has been possible to investigate
inter- and intraparticle heterogeneities in great detail. <o:p></o:p></span></p>
