Experimental methods in chemical engineering: Temperature‐programmed oxidation—TPO

The Canadian Journal of Chemical Engineering, EarlyView.
Abstract Temperature‐programmed oxidation (TPO) probes the oxidative capacity and redox properties of solid materials—catalysts, metal oxides, perovskites, and carbonaceous deposits. It identifies coke type, distribution, and reactivity. TPO instruments pass an oxidizing gas (diluted O2$$ {\mathrm{O}}_2 $$, air, or less commonly N2O$$ {\mathrm{N}}_2 ...

Experimental methods in chemical engineering: Temperature‐programmed desorption—TPD

The Canadian Journal of Chemical Engineering, EarlyView.
Abstract Temperature‐programmed desorption (TPD) characterizes the surface active sites of functional materials, such as adsorbents (metal hydrides, porous carbons, zeolites, metal–organic frameworks, for example) and catalysts. Solids surfaces are pre‐treated to remove moisture, contaminants, and previously adsorbed species, then a probe molecule (NH3$

Ni–Pd Catalytic Synergy on Rod‐Shaped CeO2 for Boosting Low‐Temperature CH4 Oxidation

EcoEnergy, EarlyView.
Introducing Ni into Pd/CeO2 markedly accelerates deep CH4 oxidation by inducing a synergistic interaction between Ni and Pd species. This synergistic effect significantly improves low‐temperature activity and long‐term stability, providing a rational strategy for efficient CH4 abatement over Pd‐based catalysts under lean CH4 conditions while reducing ...
