As an analogue to the vapor–liquid–solid process, the solution–liquid–solid (SLS) method offers a mild solution‐phase route to colloidal 1D nanostructures with controlled sizes, compositions, and properties. However, direct growth of 1D nanostructure arrays through SLS processes remains in its infancy. Herein, this study shows that SLS processes are also suitable for the growth of nanorod arrays on the substrate. As a proof of concept, seedless growth of silica nanorod arrays on a variety of hydrophilic substrates such as pristine and oxide‐modified glass, metal sheets, Si wafers, and biaxially oriented polypropylene film are demonstrated. Also, the silica nanorod arrays can be used as a new platform for the fabrication of catalysts for photothermal CO2 hydrogenation and the reduction of 4‐nitrophenol reactions. This work offers some fundamental insight into the SLS growth process and opens a new avenue for the mild preparation of functional 1D nanostructure arrays for various applications.

二氧化硅纳米棒阵列的溶液-液体-固体生长和催化应用。
与气-液-固过程类似,溶液-液-固(SLS)方法为尺寸、成分和性能受控的胶体一维纳米结构提供了温和的溶液相途径。然而,通过 SLS 工艺直接生长一维纳米结构阵列仍处于起步阶段。在此,这项研究表明,SLS 工艺也适用于在基板上生长纳米棒阵列。作为概念验证,演示了二氧化硅纳米棒阵列在各种亲水基底(例如原始和氧化物改性玻璃、金属片、硅晶片和双向拉伸聚丙烯薄膜)上的无籽生长。此外,二氧化硅纳米棒阵列还可用作制造光热CO 2加氢和4-硝基苯酚还原反应催化剂的新平台。这项工作提供了对 SLS 生长过程的一些基本见解,并为温和制备用于各种应用的功能性一维纳米结构阵列开辟了新途径。
