Abstract

Hydrogen reduction of H ₂PdCl ₄ in the presence of sodium carboxymethyl cellulose (SCMC) in dynamic thin films on a microfluidic spinning disc platform affords Pd-SCMC nano-structures. The morphology of Pd nanocomposites changed from well-connected nano-rosettes to disconnected agglomerates with an increase in SCMC concentration. These nanocomposites were drop cast on interdigitated electrodes (IDEs) to afford sensors for hydrogen gas, with a decrease and increase response in current for nano-rosettes and agglomerates structures, respectively.
