Premade and readily transportable mononuclear zero‐valent metal atoms in stock solvents offer the potential capability for bottom‐up designable metallic material fabrication. This work demonstrates a potentially universal and practical strategy to prepare weakly shielded mononuclear metal atoms in a volatile solvent, which also constitutes a strippable ligand to the metal atoms. Herein, M₁(0) (M=Pt, Au) atoms are prepared by reducing H₂PtCl₆ and HAuCl₄ with ethanol in ethylene glycol diethyl ether (EGDE) under mild temperatures. The diether oxygens of EGDE, H⁺, and Cl⁻ coordinating to the M₁(0) atoms, make the M₁(0) atoms stable in the solvent under low pH. However, the M₁(0) atoms can be released either by evaporation of HCl and EGDE or through neutralization of the HCl with a base. The premade M₁(0) atoms can be used as primary building blocks to construct designable materials. To demonstrate a potential application, the M₁(0) atoms are conveniently transported onto the surface of TiO₂ through impregnation followed by mild heating. The atomic dispersion and reduced state of the metal atoms are well preserved, as verified by HAADF‐STEM images, XPS, and DRIFT spectroscopy.

可运输的单核金属原子作为自底向上材料制造的基础材料：储备溶液中的Pt1（0）和Au1（0）原子

预制溶剂中易于运输的预制单核零价金属原子为自下而上设计金属材料的制造提供了潜在的能力。这项工作证明了在挥发性溶剂中制备弱屏蔽的单核金属原子的潜在通用和实用策略，该溶剂也构成了金属原子的可剥离配体。在此，通过在温和的温度下用乙醇在乙二醇二乙醚（EGDE）中还原H ₂ PtCl ₆和HAuCl ₄来制备M ₁（0）（M = Pt，Au）原子。EGDE，H的二醚氧⁺和Cl ^-协调于M ₁（0）的原子中，进行中号₁（0）在低pH下在溶剂中稳定的原子。但是，M ₁（0）原子可以通过蒸发HCl和EGDE或通过用碱中和HCl来释放。预制的M ₁（0）原子可用作构建可设计材料的主要构建基块。为了证明其潜在的应用，可以通过浸渍，然后温和加热，将M ₁（0）原子方便地运输到TiO ₂的表面上。HAADF-STEM图像，XPS和DRIFT光谱证实了金属原子的原子分散和还原态得到很好的保留。
