Abstract

Preferential growth among the (110) axes occurs in the preparation of Pt nanowires by reduction of [Pt(NH₃)₄]⁺ ions in the mesopores of silica MCM[-41. The nanowires, uniformly 3.0 nm in diameter and with lengths of tens to hundreds of nanometers, consist of single crystals and are stable up to 500°C. Unsupported nanowires, released by dissolving the matrix in aqueous HF, are stable up to 300°C.
