本项目针对当前国际尚难以控制的CO2温室气体排放难题，结合能源及化工原料日益增长的需要，拟通过"支撑液膜仿生方法"、"种子生长技术"和"层层组装手段"设计制备一系列对CO2具有优异光催化还原性能的，ZnO纳米柱与Fe系金属（或合金）超薄膜交替组装的，(ZnO-NPA/FeGM)n夹层多孔立体异质结构多功能材料。该材料内部囊括了"异质结""超薄膜""合金化""纳阵列""孔结构"等多种可用于调控性能的结构单元。用于CO2温室气体的光催化还原处理，可实现其合成碳氢燃（原）料反应的高转化率、高选择性、高性价比、高分离效率、以及对太阳光的高利用率。本项目的实施，不仅可以获得一系列新型多功能材料，而且可以大大推进CO2光催化还原反应走向实用的进程，从而有望实现消减CO2温室气体和获取碳氢燃（原）料的环保/能源双丰收。这无论从材料、化工来看，还是对能源、环保来说，都具有非常重要的意义。

For solving the current international CO2 greenhouse gas emissions which is still difficult to control and combining with rising energy and raw materials chemicals demands, the project intends to design and prepare a series of multifunctional materials processing the structure of (ZnO-NPA/FeGM)n three-dimensional heterogeneous porous sandwich construction which have excellent CO2 photocatalytic reduction and alternately assemble ZnO nano-pillar and Fe metals (or alloys) ultra-thin films, by adopting "Bionic supported liquid membrane method", "seed growing technology" and "layer assembly tools". The interior of materials includes a "heterojunction" "super-film" "alloying" "Nano-Array", " porous structure" and other structural elements which can be used to regulate the performance. Using the photocatalytic reduction of these kinds of materials for greenhouse gases CO2, can realize hydrocarbon fuel (raw) materials synthesis- reaction with high conversion, high selectivity, high cost, high separation efficiency and high utilization of sunlight. The implementation of this project, will not only obtain a series of new multifunctional materials, and also can greatly promote the photocatalytic CO2 reduction reaction towards practical process, which is supposed to achieve environmental / energy dual harvest by reducing greenhouse gase CO2 and obtaining hydrocarbon fuel (raw) materials. In terms of materials and chemical point of view, or the energy solution and environmental protection, it has a very important significance.
