TL;DR: This investigation reveals a pre-edge feature in the O K-edge of highly catalytically active X-ray amorphous iridium oxides that is identified as O 2p hole states forming in conjunction with Ir(III) and these electronic defects in the near-surface region of the anionic and cationic framework are likely critical for the enhanced activity of amorphously irium oxides relative to their crystalline counterparts.

TL;DR: In this article, the intermetallic compounds PdGa and Pd3Ga7 are introduced as selective catalysts for the hydrogenation of acetylene, and they are shown to have high thermal stability up to temperatures of about 600 K.

TL;DR: This study on atomically dispersed Ni species brings new fundamental understanding of Ni active sites for reactions involving CO2 and clearly evidence the limits of single-atom catalysis for complex reactions.

TL;DR: A reduction of solvent volume and a controlled washing protocol allow the synthesis of high surface area SBA-15 materials with a narrow monomodal pore size distribution for larger batch sizes.

TL;DR: In this paper, the Pd/ZnO/Al2O3 catalysts have better long-term stability when compared with commercial Cu/ZNO/al2O 3 catalysts, and are also stable under redox cycling.
