Abstract
A silicon micromonolith containing ca.40000 regular channels of 3.3 μm in diameter per square millimeter has been successfully functionalized with anAu/TiO2 catalyst for CO preferential oxidation(CO-PrOx) in the presence of hydrogen. The functionalization of the silicon microchannels has been accomplished by growing a SiO2 layer on the channel walls, followed by exchange with a titanium alkoxy deprecursor and decomposition intoTiO2 and, finally, by anchoring carbosilanethiol dendron protected p...
