Developing sustainable and clean electrochemical energy conversion technologies is a
crucial step in addressing the challenges of energy shortage and environmental pollution …

Au is usually viewed as an inert metal, but surprisingly it has been found that Au
nanoparticles less than 3–5 nm in diameter are catalytically active for several chemical …

The prevailing view of CO oxidation on gold-titanium oxide (Au/TiO2) catalysts is that the
reaction occurs on metal sites at the Au/TiO2 interface. We observed dual catalytic sites at …

We provide direct evidence of a water-mediated reaction mechanism for room-temperature
CO oxidation over Au/TiO2 catalysts. A hydrogen/deuterium kinetic isotope effect of nearly 2 …

The development of new catalysts for energy technology and environmental remediation
requires a thorough knowledge of how the physical and chemical properties of a catalyst …

The strong metal–support interaction (SMSI), which affects the catalytic performance of
supported metal catalysts, plays a central role in the modern chemical industry. However …

Density functional theory was used to study the CO oxidation catalytic activity of CeO2-
supported Au nanoparticles (NPs). Experimental observations on CeO2 show that the …

The high catalytic activity of gold clusters on oxides has been attributed to structural effects
(including particle thickness and shape and metal oxidation state), as well as to support …

Redox-active oxides find use in many applications, including catalysts, photovoltaic devices,
self-cleaning glasses, chemical sensors and electronic components. Their utility derives …

Fifteen commercial titania (titanium (IV) oxide; TiO2) powders were modified with gold by
photodeposition to prepare photocatalysts that work under irradiation with light in the visible …
