P-Band Intermediate States Mediate Electron Transfer at Confined Nanoscale

The nature of crystal facet effect of TiO2-supported Pd/Pt catalysts on selective hydrogenation of cinnamaldehyde: electron transfer process promoted by interfacial oxygen species

“…In addition, according to molecular orbital (MO) theory, the strength of the PBIS depends on the degree of overlap of O 2p orbitals at the interface, which is related to the electronic structure and spatial orientation of the oxygen species, as well as the spatial distance between them. 59 Based on this model, the crystal facet effect of the TiO 2 supports, and the metal effect on the activity and selectivity in the hydrogenation reaction can therefore be attributed to the differences (density and binding strength) in the interfacial oxygen species of each crystal facet and metal. Taking TiO 2 -100-Pd and TiO 2 -101-Pt catalysts as examples (Fig.…”

Rare earth oxide based electrocatalysts: synthesis, properties and applications

“…The results of Raman and XPS spectra show that the oxygen vacancy and co-redox at the interface of CeO 2 and CuO enhance the catalytic activity. 77 In addition to enhancing the HER activity of CeO 2 by building a heterogeneous interface, and the other composite strategies can also improve its electronic structure and enhance its catalytic activity. Du et al prepared selective selenium (Se)doped Co 3 O 4 @CeO 2 NPs point-like nanoneedle array by three continuous operations: mild hydrothermal, air calcination and selective selenization.…”
