Profiling a catalyst: In this work, we report the profiles of deactivating species (coke) along the catalyst used in the cracking of waste polyethylene, using combined visible, FTIR, and Raman microscopies. The results show a gradient of concentration of aromatic and aliphatic structures within the particles.
