In previous work, we optimized catalytic Pd-based nanoparticles in lignocellulose, and demonstrated how to post-process them via Natural Fiber Welding (NFW) into free-standing structures to catalytically remove nitrates from drinking water. In the current study, we present a novel Pd bimetal system that exhibits distinctly different magnetic or nanomagnetic properties depending on the composition of the nanoparticle. Using a variety of spectroscopic and magnetic measurement techniques, we explore how nanoparticle composition and structure relate to each system’s observed magnetic properties, and how some show nanomagnetic behavior at low temperature. We then discuss how these sustainably-supported nanoparticle systems may be post-processed via NFW into advanced functional materials for magnetic sensing and/or catalytic applications.
