原始语种摘要: Abstract(#br)The one-dimensional metal-semiconductor hybrids with directed photogenerated carrier separation rather than random flow direction of photogenerated electrons and holes possess more advantages to achieve long-distance charge separation and efficient solar energy conversion efficiency. Here, we obtained the non-centrosymmetric Au /TiO 2 nano-mushrooms (Au/TiO 2 NMs) structures. The one-dimensional hybrid simultaneously maintains directed spatial charge separation properties and tunable light absorption. Owing to the well-designed structure, the H 2 evolution rate can reach up to 52.6 μmolg −1 h −1 under sunlight irradiation from pure water without any sacrificial reagents. Based on the photocatalytic data, we can speculated that the...
