Photothermal nanoreactor with rapid charge transfer and improved spectral utilization is a key point in photocatalysis research. Herein, silver sulfide quantum dots (Ag₂S QDs) were coating on the surface of porous graphitic carbon nitride nano vesicles (PCNNVs) to form Ag₂S/PCNNVs nanoreactors by a simple calcination method for obtaining efficient photothermal-assisted photocatalytic hydrogen (H₂) evolution under simulated/real sunlight irradiation. In particularly, the as-prepared optimal 3% Ag₂S/PCNNVs sample exhibited the H₂ production rate of 34.8 mmol h⁻¹ g⁻¹, which was 3.5 times higher than that of bare PCNNVs. The enhancement of photothermal-assisted activity over the Ag₂S/PCNNVs composite system is mainly attributed to the coupling of the photothermal conversion performance of Ag₂S QDs and the thermal insulation performance of PCNNVs based on the plasmonic coupling-boosted photothermal nanoreactor. This study presents a promising strategy for the development of high-efficient photothermal-assisted photocatalysts.

具有快速电荷转移和提高光谱利用率的光热纳米反应器是光催化研究的关键点。本文将硫化银量子点（Ag ₂ S QDs）涂覆在多孔石墨氮化碳纳米囊泡（PCNNVs）表面，通过简单的煅烧方法形成Ag ₂ S/PCNNVs纳米反应器，从而获得高效的光热辅助光催化氢（H ₂）模拟/真实阳光照射下的演化。特别是，所制备的最佳3% Ag ₂ S/PCNNVs样品的H ₂生产率为34.8 mmol h ^-1 g ^-1，比裸PCNNVs高3.5倍。_{Ag 2} S/PCNNVs复合体系光热辅助活性的增强主要归因于基于等离子体耦合增强光热纳米反应器的Ag _{2 S量子点的光热转换性能和PCNNVs的隔热性能的耦合。}这项研究为开发高效光热辅助光催化剂提供了一种有前途的策略。
