Hydrothermal Synthesis of MoO2 Nanoparticles Directly onto a Copper Substrate Michael McCrory a, Ashok Kumar a,b and Manoj K. Ram b a Department of Mechanical Engineering, University of South Florida, Tampa, Florida 33620, USA b Clean Energy Research Center, College of Engineering, University of South Florida, Tampa, FL 33620, USA ABSTRACT Recently, molybdenum oxide (MoO2) has been found to be a chemically stable and relatively inexpensive material for the application as the anode in a lithium ion battery [1-5]. We believe the use of MoO2 in battery applications has been hindered due to a long, complicated, and multistep synthesis process. We present a simple one-pot hydrothermal technique to synthesize MoO2 nanoparticles directly onto a copper (Cu) substrate. We believe this is a first report of the synthesis of MoO2 directly onto a Cu substrate, and could lead to the ability to both fabricate other materials in a similar manner as well as depositing MoO2 onto other substrates. This technique can reduce anode production time by eliminating the coating process, and also decrease the total amount of chemicals used when compared to a typical powder synthesis and coating processes. The MoO2 coated Cu electrode was characterized using Raman Spectroscopy, Grazing Incident X-ray Diffraction (GIXRD) and scanning electron microscopy (SEM) techniques to confirm the composition, crystallinity and structure of the synthesized MoO2 nanomaterial. INTRODUCTION In an effort to speed up the process of fabricating the anode for a lithium ion battery, a method needed to be developed to synthesize MoO2 nanoparticles directly onto a copper substrate. In a normal process, the nanoparticles would have to first be synthesized, separated and dried, then mixed with a binder and solvent, coated onto the substrate and finally dried in an oven [6-8]. If these extra steps could be eliminated, it would take less time to fabricate each sample and fewer chemicals would have to be used since there would be no need for a binder and solvent. EXPERIMENTAL All chemicals used in this experiment were purchased from Sigma Aldrich and were used without any further processing unless otherwise noted. To begin the experim
