In recent years, much effort has been focused on the development of the photocatalysts with high performance under visible light irradiation. In this paper, three-dimensional porous La-doped SrTiO3 (LST) microspheres were prepared by a modified sol–gel method, in which the agarose gel/SrCO3 microsphere and La2O3 were employed as the template and the La resource, respectively. The as-prepared LST microspheres exhibit a porous structure with a diameter of about 10 µm and a surface pore size of about 100 nm. The La element was doped into the crystal lattice of SrTiO3 by the substitution of La3+ for Sr2+. Therefore, the absorption edge of LST samples shifts toward the visible light region, and their photocatalytic activity for the Cr(VI) reduction is enhanced under visible light. Among all LST samples, LST-0.5 (the La3+ doping content is 0.5 wt-%) exhibited the highest visible-light photocatalytic activity, which can reduce 84% Cr(VI) within 100 min. This LST materials may become a promising photocatalyst for the facile treatment of wastewater containing poisonous heavy metal ions.

近年来,人们对信息处理的需求日益增长,脑启发式神经形态器件得到了广泛的关注。突触器件作为一类重要的神经形态器件,在短短几年内迅速升温。在用于制备突触器件的各种材料中,半导体纳米晶体(NCs)因其优异的电学和光学性能而成为首选材料之一。本综述论文首先介绍了基于半导体纳米晶体的突触器件的研究背景及半导体纳米晶体的基本性质。然后,根据器件有源层所用纳米晶体种类的不同,分类介绍了基于纳米晶体的突触器件的最新研究进展。最后,讨论了基于半导体纳米晶体的突触器件目前仍面临的问题和挑战。

磷化锡(SnP)具有极佳的锂离子扩散能力和高理论比容量,是高功率锂离子电池的理想负极材料。然而,SnP的合成难度高,大尺寸晶粒导致的电化学不可逆也阻碍了其应用。根据密度泛函理论(DFT)计算,使用原位催化磷化方法可以显著降低SnP的相对生成能。因此,在还原氧化石墨烯(rGO)包裹的碳骨架内合成了SnP/CoP异质纳米晶。所得复合材料具有超快充放电能力(50 A·g−1时容量为260 mA·h·g−1),且循环1500次不会出现容量衰减(2 A·g−1时容量为645 mA·h·g−1)。充放电机理分析表明尺寸为4.0 nm的SnP/CoP纳米晶具有高反应可逆性,且CoP在较高电位生成的金属Co加速了低电位SnP反应的动力学,从而赋予材料超快充放电能力。相对电流密度的有限元模拟进一步验证了这一现象。
