    Abstract
    CO2-to-ethanol conversion is achieved using a superhydrophobic Cu2O hollow structure (O–CHS) by continuous CO2 transport, which maintains a high CO2 concentration on the catalyst surface and further lowers the energy barrier for C–C coupling.

    【要点】：本研究提出一种利用超疏水性Cu2O纳米围栏实现太阳能驱动CO2至乙醇转化的新策略，显著提高了乙醇生成速率。
    

    【方法】：通过设计超疏水性Cu2O介孔空心结构（O-CHS），该结构能在水面上浮动并作为纳米围栏，有效阻止水分渗透至内部空间，促进CO2在反应位点的高浓度积累。
    

    【实验】：实验使用O-CHS作为催化剂，在连续CO2传输的条件下进行光催化反应，实现了996.18 μmol g(-1) h(-1)的乙醇生成速率，创下了已知最高记录。
