SU Chemists Develop ‘Fresh, New’ Approach to Making Alloy Nanomaterials

Potential applications include gas storage, heterogeneous catalysis and lithium-ion batteries

Chemists in The College of Arts and Sciences have figured out how to synthesize nanomaterials with stainless steel-like interfaces. Their discovery may change how the form and structure of nanomaterials are manipulated, particularly those used for gas storage, heterogeneous catalysis and lithium-ion batteries.

The findings are the subject of a July 24 article in the journal Small (Wiley-VCH, 2013), co-authored by associate professor Mathew M. Maye and research assistant Wenjie Wu G’11, G’13.

Until now, scientists have used many wet-chemical approaches—collectively known as colloidal synthesis—to manipulate reactions in which metallic ions form alloys at the nanoscale. Here, metal nanoparticles are typically 2 to 50 nanometers in size and have highly unique properties, including various colors, high reactivity and novel chemistry.

Maye and Wu are part of a growing team of international chemists and materials scientists devising new ways to alter the size, shape and composition of nanoparticles.

“At SU, we have developed a new synthetic pathway to tailor the internal microstructure of nanomaterials,” says Maye, whose research spans inorganic chemistry, catalysis, materials science, self-assembly and biotechnology.
