Understanding plant water-use patterns is important for improving water-use efficiency and for sustainable vegetation restoration in arid and semi-arid regions. However, seasonal variations in water sources and their control by different sand-fixing plants in water-limited desert ecosystems remain poorly understood. In this study, stable isotopic ratios of hydrogen(δ^(2)H) and oxygen(δ^(18)O) in precipitation, soil water, groundwater, and xylem water were determined to document seasonal changes in water uptake by three representative plant species(Pinus sylvestris var. mongolica Litv., Amygdalus pedunculata Pall., and salix psammophila) in the northeastern Mu Us sandy land, Northwest China. Based on the depth distribution and temporal variation of measured gravimetric soil water content(sWC), the soil water profile of the three species stands was divided into active(0.01 g g^(-1)sWC t of variation(CV) stable(0.02 g g^(-1)sWC st(0.08 g g^(-1)sWC 45%) layers. Annually, P. sylvestris, A. pedunculata, and s. psammophila obtained most water from deep(59.2%±9.7%, moist layer and groundwater),intermediate(57.4%±9.8%, stable and moist layers), and shallow(54.4%±10.5%, active and stable layers) sources, respectively. seasonally, the three plant species absorbed more than 60% of their total water uptake from the moist layer and groundwater in the early(June) dry season;then, they switched to the active and stable layers in the rainy season(July–september) for water resources(50.1%–62.5%). In the late(October–November) dry season, P. sylvestris(54.5%–66.2%) and A. pedunculata(52.9%–63.6%) mainly used water from stable and moist layers, whereas s. psammophila(52.6%–70.7%) still extracted water predominantly from active and stable layers. Variations in the soil water profile induced by seasonal fluctuations in precipitation and groundwater levels and discrepancies in plant pheno

光电极通常由半导体吸光层和导电集流体两部分组成,两者间的界面电子结构直接影响导电集流体从半导体光吸收层中收集光生电荷的效率,尤其对于具有3D界面结构的液态金属镶嵌半导体颗粒的光电极.为此,本工作通过改变金属组分改变液态金属的功函数,从而调节导电集流体与半导体吸光材料间3D界面的电子能带排列和接触类型,促进光生电荷的跨界面转移与收集,提升光电极的光电化学分解水活性.系统研究半导体与液态金属的功函数匹配关系发现,将ZnO颗粒嵌入铟锡(It)低温液态金属中,会形成欧姆接触;而将其嵌入铋铟锡(BIt)低温液态金属中,则会形成肖特基接触.由于欧姆接触不存在肖特基接触的界面能垒而有利于光生电荷的跨界面转移与收集,因此,与铟锡低温液态金属镶嵌ZnO颗粒的光电极(It/ZnO)相比铋铟锡低温液态金属镶嵌ZnO颗粒的光电极(BIt/ZnO)具有更为优异的电荷收集和分离能力,其光电化学分解水光电流密度可达0.62 mA cm^(-2),相比BIt/ZnO光电极的光电流密度(0.52 mA cm^(-2))提升了约19%,且在已报道的代表性ZnO光电极中处于前列.而与之相比,WO3、tiO_(2)或Cu2O因分别与It和BIt形成相同的欧姆或肖特基型接触,两种低温液态金属镶嵌的WO3、tiO_(2)或Cu2O光电极具有几乎相同的光电催化活性.本工作展示了通过选择具有不同功函数的液态金属来改变金属/半导体接触类型以增强低温液态金属镶嵌半导体光电极性能的潜力,为规模化构建高效光电极提供了新的策略.
