光触媒的二酸化炭素還元のための共有結合性有機構造体を利用した単一原子触媒の創製

在这一年里，我们继续专注于合成各种离子金属硫化物纳米（NC）异质结构作为潜在的光催化剂，用于CO2还原。通过阳离子交换（CE）反应中的一种特殊的形貌演化过程，合成了具有可调组分的NC异质结构。这种板状纳米碳的组成和结构的微调使得能够宽范围地调整混合异质结构中不同相的能带位置和能带对准，从而使我们能够准确地控制光催化CO2还原中中间体和产物的形成。

In this year, we continuously focused on the synthesis of various ionic metal sulfide nanocrystal (NC) heterostructures as the potential photocatalysts for CO2 reduction. The NC heterostructures integrated with tunable compositions were synthesized by a special waning and waxing morphological evolution process in cation exchange (CE) reaction. This fine-tuning of the composition and structure in plate-shaped NCs enables a wide-range adjustment of the band positions and band alignments of different phases in the hybrid heterostructures and thus allows us to an accurately control the formation of intermediates and products in the photocatalytic CO2 reduction.
