We propose that these metal oxides undergo hydrogen spillover <em>via</em> initial hydride transfer followed by tautomerization of the surface hydride, giving reduced sites and OH bonds. This mechanism is in contrast to the traditional spillover mechanism involving discrete proton- and electron transfer steps.

The study showed that different calcination temperatures and calcination atmospheres affected the activation state of Pt species, showing significant differences in the photothermal catalytic toluene oxidation reaction efficiency. The Pt-P25-800N sample activated in a nitrogen atmosphere at 800 °C exhibits better activity compared to other samples, achieving a toluene conversion rate of 95% and mineralization rate of 65% under a light intensity of 400 mW cm<small>⁻²</small>. Characterization results demonstrate that low-valent Pt species are positively correlated with toluene oxidation activity and play a major role in the reaction. The ultraviolet (UV), visible (vis) and infrared (IR) components in the spectrum all contribute to the toluene oxidation process. The catalytic bed is heated to the required temperature mainly through thermal effects, thus overcoming the reaction energy barrier. The traditional photocatalytic process over TiO<small>₂</small> also plays an auxiliary enhancement role. Due to the efficient conversion capability of the active sites, Pt-P25-800N achieves long-term stability of at least 50 hours under low light intensity input and water vapor conditions, accompanied by minimal accumulation of intermediate products.

In this study, the effect of thermal aging on the nanostructure and TWC performance of the physically mixed powder catalyst (Pd/A + Cu/A) was investigated under different environments, that is, simulated exhaust gas mixtures dynamically fluctuating among stoichiometric, fuel-lean, and fuel-rich (SLR) compositions, compared with static fuel-lean (L) and air at 600–900 °C. The observed thermal deactivation was strongly dependent on aging atmosphere, and it increased in the sequence air &lt; L &lt; SLR with increasing aging temperature.

During SLR aging, some of the incorporated Cu<small>²⁺</small> species migrated to the surface, reduced to the metallic state, and immediately reacted with Pd metal to form a Pd–Cu random alloy with face-centered cubic structure.

Therefore, catalysts play an important role in lowering the activation barrier, and thereby enhancing the activity and reaction rate, and they also govern the product selectivity <em>via</em> control of the reaction pathway on the catalyst surface. The metal–support interaction (MSI) is a unique interaction occurring at the interface of metal nanoparticles and metal oxide supports in the solid-phase heterogeneous catalysts, which changes the electronic properties of the catalyst surface and hence the catalytic process. The control of MSI in the design of heterogeneous catalysts provided many opportunities for developing advanced catalysts having better catalytic performance.
