The solution-liquid-solid (SLS) mechanism is a well-established method for forming one-dimensional (1D) nanostructures in a solution. Herein, an SLS mechanism is explored for the formation of metal oxides for the first time. Two key synthetic achievements allow this synthesis: (i) the design of a tailored catalyst with a low melting point and high stability and (ii) control over the reactivity and the oxidation of the precursors. Once these conditions are achieved, the SLS growth of indium and tin oxides ensues. Structural characterization of the products at various stages of the growth confirms the formation of 1D In2O3 and SnO2 nanoscale heterostructures using AuIn2 and Au7Sn3 as catalysts. Furthermore, SLS growth was easily adopted to insert SnO2 rods selectively between two domains of an Au/ZnO heterodimer, demonstrating the potential of achieving highly complex multicomponent metal-oxide nanostructures.
