2D-Arrays of Nanoparticles as Model Catalysts

摘要: From studies on supported model catalysts, we know that the reactivity of catalysts depends size and shape metal nanoparticles but also for some reactions it can depend distance between them. We discuss recent methods to prepare regular arrays catalysts. One these is based growth clusters a template (graphene or h-BN monolayers ultrathin oxide film single crystal) allows study effects down few atoms. A second method uses self-assembled micelles from diblock co-polymers, produces hexagonal large area flat supports which are well suited (1–10 nm) density clusters. third using colloidal synthesis able produce in quantity with very narrow distribution spontaneously self-organize area. This promising studying effect particles catalytic activity selectivity. other like electron beam nanosphere lithography less fabrication Finally make remarks about likely evolution
