Research efforts over the past few decades have led to a vast synthetic methodology affording precise control over nanoparticles size, shape, and composition. These synthetic capabilities have facilitated the study of material properties across length scales, with nanoparticles often displaying unique or enhanced properties relative to their bulk counterparts. However, while some synthetic protocols employ water as solvent, the majority rely on non-environmentally friendly solvents. As nanoparticles transition from the lab setting to real world applications it is important to consider alternate solvents. Cyrene is a high-boiling point “green” solvent produced from cellulose. In this presentation, we will discuss the use of Cyrene as a solvent for the synthesis of Ag and Pd nanoparticles. Preliminary results from NMR, GC-MS, and FTIR analysis before and after nanoparticles synthesis suggest Cyrene plays a dual role, acting as solvent and reducing agent. The synthesized nanoparticles were characterized using powder X-ray diffraction and Transmission Electron Microscopy.
