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

在这一年中，我们继续致力于各种离子金属硫化物纳米晶（NC）异质结构的合成，作为潜在的CO2还原光催化剂。在阳离子交换（CE）反应中，通过一种特殊的渐弱和渐旺的形态演变过程合成了具有可调成分的NC异质结构。这种对板状纳米结构的组成和结构的微调，使得杂化异质结构中不同相的能带位置和能带排列可以进行大范围的调整，从而使我们能够准确地控制光催化CO2还原过程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.
