The progress of this project has gone well with our expectation. Direct observation of near-infrared (NIR) light-induced plasmonic hot hole transfer was successfully made at a heterointerface in CdS/CuS heterostructured nanocrystals (HNCs). This part was published in the top journal (Z. Lian et al., Nature Commun. 2018, 9, 2314). The CdS/Cu7S4 HNCs with the morphology of heterodimers were successfully synthesized. They formed a novel plasmonic p-n junction, which overcame the ultrafast electron relaxation through hot electron injection and achieved extraordinarily long-lived charge separation (> 273 μs). The CdS/Cu7S4 HNCs exhibited high photocatalytic activity in hydrogen evolution under near- or short-wave infrared light irradiation. This part was published in the top journal (Z. Lian et al., J. Am. Chem. Soc. 2019, 141, 2446-2450). In addition, this article was selected as a Journal Cover Picture.Next, durian-shaped CdS/ZnSe heterostructured semiconductor nanocrystals (d-CdS/ZnSe NCs) were successfully synthesized and the mechanism of formation processes were well explored. The d-CdS/ZnSe NCs exhibited high activity for H2 evolution due to the ultra-long lived charge separation (> 6.2 ms) and efficient hole transfer to the mesoporous shell. This part was published in a specific journal (Z. Lian et al., J. Phys. Chem. Lett. 2018, 9, 2212-2217).

这个项目的进展和我们预期的一样顺利。在CdS/CuS异质结构纳米晶体（HNC）异质界面上，直接观测到近红外光诱导的等离子体激元热空穴转移.该部分已发表在顶级期刊（Z. Lian等人，自然通讯2018，9，2314）。成功合成了具有异二聚体形貌的CdS/Cu 7S 4 HNC。他们形成了一种新型的等离子体p-n结，通过热电子注入克服了超快电子弛豫，实现了超长寿命的电荷分离（> 273 μs）。CdS/Cu 7S 4 HNC在近红外或短波红外光照射下表现出较高的光催化析氢活性。该部分已发表在顶级期刊（Z. Lian等人，J. Am. 2019，141，2446-2450）。其次，成功合成了榴莲状CdS/ZnSe异质结构半导体纳米晶（d-CdS/ZnSe NCs），并对其形成机理进行了探讨。由于超长寿命的电荷分离（> 6.2 ms）和有效的空穴转移到介孔壳层，d-CdS/ZnSe纳米碳表现出高的放氢活性。这部分发表在一个特定的杂志（Z。Lian等人，《物理化学杂志》2018，9，2212-2217）。
