Gold nanoparticles (partially below 5 nm in diameter) were successfully deposited on hexagonal and monoclinic WO3 supports by deposition–precipitation, which had been considered previously not feasible owing to the low isoelectronic point of WO3. The catalysts were characterized by TEM, SEM, N2-adsorption, XRD, and XPS. In CO oxidation m-WO3/Au showed better catalytic activity over 100 °C than h-WO...
