Specifically, ¿-SnWO4 spikecubes were entitled on the basis of the peculiar morphology, wherein bundles of nanopillars were self-aligned with quasi-periodicity onto each sharp face of hexahedral cube cores. Moreover, this geometric engineering was particularly carried out on a Scheelite-type (ABO4) ¿-SnWO4 crystal with a visible-light-active band gap of 2.91 eV and subtle conduction and valence band positions, endowing the photoexcited electron-hole pairs on ¿-SnWO4 with strong reducing and oxidizing power, respectively. Consequently, an outstanding photocatalytic activity in degrading organic dyes was observed for the ¿-SnWO4 spikecube with an enhancement more than 150% in comparison with a benchmark visible-light-active WO3 photocatalyst. By contrast, the design of Au@Nb@HxK1-xNbO3 emulates the growth pattern of a natural plant ¿ a peapod ¿, wherein sub-10 nm core-shell Au@Nb plasmonic bimetallics as the particulate peas seeded discretely inside the unidirectional cavity of the tubular HxK1-xNbO3 semiconductor as the pod. The biomimicry of this configuration endows the Au@Nb@HxK1-xNbO3 nanopeapods with strong light harvesting abilities, wherein the HxK1-xNbO3 nanopod and the Au@Nb nanopeas absorb ultraviolet and visible light via interband transition and surface plasmon resonance, respectively. More importantly, the strong near-field plasmon-plasmon coupling between neighboured Au@Nb nanoparticles allows the Au@Nb@HxK1-xNbO3 nanopeapod absorbing near-infrared light. Last but not least, dye photodegradation and water photoelectrolysis as proofs-of-concept manifested the full-spectrum utilization of diffusive solar energy by the Au@Nb@HxK1-xNbO3 nanopeapod for environmental remediation and fuel generation, respectively.\u003c\/p\u003e\u003cdiv class=\"aw-variant-hidden-subtitle-div\" id=\"aw-variant-subtitle-9783736997806\"\u003e\u003ch3\u003e\u003c\/h3\u003e\u003c\/div\u003e","brand":"Libri","offers":[{"title":"Softcover - 9783736997806","offer_id":39443269222493,"sku":"9783736997806","price":69.9,"currency_code":"EUR","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0940\/0622\/files\/f7922c38-bc92-4922-9287-38bfff361466.jpg?v=1781328406","url":"https:\/\/shop.autorenwelt.de\/products\/advanced-nanoarchitectures-with-photocatalytic-functionality-von-chen-ying-chu","provider":"Autorenwelt Shop","version":"1.0","type":"link"}
