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).

这个项目的进步与我们的期望相处得很好。直接观察近红外（NIR）光诱导的血浆热孔转移，在CDS/CUS异质结构的纳米晶体（HNC）中成功地进行了杂气。这部分发表在《顶级期刊》（Z​​. Lian等人，自然界，2018，9，2314）中。具有异二聚体形态的CDS/CU7S4 HNC已成功合成。他们形成了一种新型的等离子P-N连接，通过热电子注入克服了超快电子弛豫，并实现了非常长的电荷分离（>273μs）。 CDS/CU7S4 HNC在近波或短波红外光照射下暴露了氢进化中的高光催化活性。该部分发表在《顶级期刊》（Z​​. Lian等，J。Am。Chem。Soc。2019，141，2446-2450）中。此外，本文被选为期刊封面图片。次要，榴莲形状的CD/ZNSE异质结构的半导体纳米晶体（D-CDS/ZNSE NC）成功合成了，并且很好地探索了地层过程的机制。由于超长的活电荷分离（> 6.2 ms）和有效的孔转移到中孔外壳，因此D-CDS/ZNSE NC暴露了H2演化的高活性。该部分发表在特定期刊上（Z. Lian等，J。Phys。Chem。Lett。2018，9，2212-2217）。
