“…The average pressure at entrance and exit of the reaction cell is defined to be the pressure of gas around the catalyst loaded on a sample holder assembled in the reaction cell. A more detailed description of the inhouse AP-XPS system can be found in our previous publications [7,25,[29][30][31][32][33][34].…”

Low temperature water-gas shift (WGS) catalysts, Pd nanoparticles supported on a-MnO 2 nanorods termed Pd/a-MnO 2 and Pt nanoparticles supported on aMnO 2 nanorods termed Pt/a-MnO 2 were synthesized by introducing Pd or Pt precursor to well-prepared a-MnO 2 nanorods through precipitation deposition with a following annealing at 300°C. They are quite active for WGS in the temperature range of 140-350°C. Activation energies for WGS on Pd/a-MnO 2 and Pt/a-MnO 2 are 45.3 and 56.4 kJ/mol respectively, comparable to precious metal supported on CeO 2 and TiO 2 for WGS. Surface chemistries of the two catalysts during WGS were tracked with ambient pressure X-ray photoelectron spectroscopy. Different from the preservation of the surface and bulk phase of other oxide support such as CeO 2 , TiO 2 in CeO 2 -or TiO 2 -based WGS catalysts, both surface and bulk of aMnO 2 nanorods of Pd/a-MnO 2 and Pt/a-MnO 2 are transited to MnO during WGS. In-situ studies identified oxygen vacancies of the formed MnO support during WGS and the metallic state of Pd and Pt nanoparticles supported on the nonstoichiometric MnO. Graphical Abstract

“…This along with the absence of peaks at 930.4 eV (Cu 0 ) and at 932.7 eV (Cu 1+ ) indicates that Cu is fully oxidized in its Cu 2+ state. The peak can be attributed to the formation of CuFe 2 O 4 and CuO [37]. After annealing, we observe the formation of a new peak at $932.5 eV.…”

“…Second, the welldefined model catalysts can be characterized by surface-sensitive instruments under various pretreatment and reaction conditions, thus helping with the identification of reaction intermediates and the correlation of kinetics data with active sites. [154][155][156] Rodriguez and co-workers performed pioneering surface science studies on low-temperature WGS catalysts. They nicely studied gold nanoclusters/nanoparticles supported on a well-defined CeO 2 (111) or rough CeO 2 films as model catalysts.…”

Since the pioneering finding by Haruta et al. that small gold nanoparticles on reducible supports can be highly active for low-temperature CO oxidation, the synthesis, characterization, and application of supported gold catalysts have attracted much attention. The water-gas shift reaction (WGSR: CO + H 2 O = CO 2 + H 2 ) is important for removing CO and upgrading the purity of H 2 for fuel cell applications, ammonia synthesis, and selective hydrogenation processes. In recent years, much attention has been paid to exploration the possibility of using supported gold nanocatalysts for WGSR and understanding the fundamental aspects related to catalyst deactivation mechanisms, nature of active sites, and reaction mechanisms. Here we summarize recent advances in the development of supported gold catalysts for this reaction and fundamental insights that can be gained, and furnish our assessment on the status of research progress.
