Journal ArticleDOI

Aqueous Au-Pd colloids catalyze selective CH4 oxidation to CH3OH with O2 under mild conditions

TL;DR: It is demonstrated that the resulting methanol incorporated a substantial fraction of gas-phase O2, suggesting that the controlled breakdown of H2O2 activates methane, which subsequently incorporates molecular oxygen through a radical process.
Journal ArticleDOI

Palladium-tin catalysts for the direct synthesis of H2O2 with high selectivity

TL;DR: It is shown that the addition of tin to palladium catalysts coupled with an appropriate heat treatment cycle switches off the sequential hydrogenation and decomposition reactions, enabling selectivities of >95% toward H2O2.
Journal ArticleDOI

Identification of single-site gold catalysis in acetylene hydrochlorination

TL;DR: An in situ x-ray absorption fine structure study of gold/carbon (Au/C) catalysts under acetylene hydrochlorination reaction conditions is performed and it is demonstrated that highly active catalysts comprise single-site cationic Au entities whose activity correlates with the ratio of Au(I):Au(III) present.
Journal ArticleDOI

The X-ray photoelectron spectra of Ir, IrO2 and IrCl3 revisited

TL;DR: In this article, the X-ray photoelectron spectra of metallic iridium and the technologically important iridium compounds, IrO2 and IrCl3, have been studied and the results not only improve the accuracy of published data but also expand the binding energy database of other iridium core-levels.
Journal ArticleDOI

Strategies for designing supported gold-palladium bimetallic catalysts for the direct synthesis of hydrogen peroxide.

TL;DR: Through treatment of the support with acids prior to the deposition of the gold-palladium bimetallic particles, the author can obtain a catalyst that can make hydrogen peroxide at a very high rate without decomposing or hydrogenating the product.
