Unprotected and interconnected Ru⁰ nano-chain networks: advantages of unprotected surfaces in catalysis and electrocatalysis.

ABSTRACT: Seedless, surfactantless and support-free unprotected, metallic, interconnected nano-chain networks of ruthenium nanoparticles (NPs) were successfully synthesized via the reduction of ruthenium(iii) chloride (RuCl₃) with sodium borohydride (NaBH₄) at three different temperatures, viz. 30 °C, 45 °C and 60 °C. The molar ratio of RuCl₃ solution and borohydride was optimized to be 1 : 1.5 to produce stable colloids with the optimum final solution pH of 9.7 ± 0.2. Average diameters of the interconnected nano-chain networks prepared at 30 °C (Ru-30), 45 °C (Ru-45) and 60 °C (Ru-60) were 3.5 ± 0.5 nm, 3.0 ± 0.2 nm and 2.6 ± 0.2 nm respectively. The morphology and composition dependent catalytic and electrocatalytic activities of these unprotected Ru
