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.

在这一年里，我们一直专注于各种离子金属硫化物纳米晶(NC)异质结构的合成，作为潜在的二氧化碳还原光催化剂。通过阳离子交换(CE)反应中特殊的弱化和蜡化的形态演化过程，合成了具有可调组成的纳米异质结构。这种对板状纳米碳管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在很大范围内进行调整，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。
