Summary: This study investigates the catalytic activity of ceria supported Au nanoclusters with different ligands (thiolates, phosphines, and a mixture) in CO oxidation reaction. The results show that thiolate-protected Au-25/CeO2 exhibits significantly higher CO conversion after activation at 250 degrees C compared to cluster catalysts with phosphine ligands. It was also found that the phosphine ligands decompose and expose the free Au surface, but temperatures higher than 250 degrees C are needed for their efficient removal from the catalyst system. Furthermore, the residues on the support have a greater influence on reactivity than the gold particle size.

Summary: MnOx-based oxides are efficient catalysts for elemental mercury oxidation in flue gas, and combining with CeO2 or CeO2-ZrO2 enhances their catalytic activity. The new MnOx-CeO2-ZrO2 solid solution catalyst showed better Hg-0 oxidation performance compared to the MnOx/CeO2-ZrO2 supported catalyst. Mn4+ and surface active oxygen were identified as the active species in Hg-0 oxidation reactions, and SO2 significantly inhibited the activity of MnOx/CeO2-ZrO2 but had less impact on MnOx-CeO2-ZrO2 solid solution.

Summary: A designed Au4Cu4/CNT nanocluster system catalyzes the CuAAC reaction of terminal alkynes without alkyne deprotonation, unlike the classic mechanism involving a sigma,pi-alkynyl intermediate. DFT results confirmed the activation of HC CPh by pi-complexation with Au4Cu4. The specificity of Au4Cu4 involving synergy between Cu and Au was shown by the inactivity of internal alkynes under the same conditions for both Au-11/CNT and Cu-11/CNT catalysts.
