Photoassisted Chemical Transformation of Cu₂O Nanooctahedra into Cu₂S Quantum-Dot Superstructures: Structural and Photoelectrochemical Properties.

ABSTRACT: Copper sulfides represent a broad range of chemical compounds, including naturally occurring minerals and wet-chemically synthesized nanoparticles. Tailoring the size, shape, and chemical composition of Cu_2‑x S nanoparticles enables the tuning of their optical and electronic properties allowing the switch between semiconducting and plasmonic characteristics. While the sulfidation of metals and metal oxides can even occur spontaneously under ambient storage conditions, the targeted synthesis of Cu_2‑x S nanoparticles mostly relies on the use of inorganic sulfur compounds. Inspired by the natural sulfidation reactions, a novel approach is developed in this paper to transform sacrificial Cu₂O nanooctahedra by a short-chain organic thiol (β-mercapt
