                                主讲内容:Semiconducting nanostructures are currently under intense scrutiny for their ability to harvest light, and to generate charge carriers which can promote the splitting of water or the reduction of CO2, leading to the sustainable formation of fuels such as hydrogen, methanol or methane. Two main routes are currently exploited. In the first one (so called Z scheme), the nanostructure is bound to the surface of an electrode, which either serves of photoanode or of photocathode. Such nanostructures, which are usually constructed by a top-down approach, can incorporate an exquisite level of refinement and complexity, but a limited active surface. Another approch consists in incorporating both the anode and the cathode within a single nanoparticle. This approach leads to materials with high surface and commensurate catalytic activity. However, usual bottom-up synthetic methods usually do not afford a high level of sophistication on the spatial arrangement of the various phases constituting these nanoparticles. To address this problem, we have developed methods whereby inorganic/organic hybrid colloids are first self-assembled before being converted into highly active photocatalysts which are able to split water under visible light. With this method in hand, we were able to conceive and prepare sophisticated free-standing photocatalytic nanoparticles with high activity in water splitting under visible light. Thus, colloid self-assembly is a powerful method to design photocatalysts for artificial photosynthesis. This communication will present several examples of nanoparticle architectures including various examples of heterojunctions, plasmonic and/or upconverting photocatalsyts, and semiconductors exploiting whispering gallery mode resonances.
