• Studied carboxylic acid reactivity on Anatase TiO2(101) single crystals and deposited nanoparticles by TPD in UHV• Designed and built a heated quartz tube (up to 500℃) ketene source for introducing ketene in situ into UHV to prove ketonization reaction mechanism• Assembled Knudson cell evaporator and deposited MoO3 clusters onto Anatase single crystal in UHV for kinetics study• Observed key reaction intermediates of carboxylic acid on anatase by reflective adsorption FTIR• Identified surface structure, surface species, and orientation of the Anatase TiO2(101) single crystals by LEED• Examined film formation and the morphology and distribution of nanoparticles deposited on substrate by SEM• Developed Python scripts to automate the processing and plotting of large-scale IR scan data (100+ files per day) and TPD data (40+ files of 10 masses per day), reducing the analysis time by 90% compared to Origin Pro• Collaborated within a multidisciplinary team with members from scanning microscopy field to ambient pressure flow reactor field
