Abstract

Metal-Organic Frameworks are crystalline structures that consist of metal ion clusters in the center with organic ligands. These structures are incredibly porous and hold promise for increasing the conductivity of chemiresistive sensors for gasses and for improving the potential in photovoltaic cells. Modifying MOF's modular framework with bimetallics utilize semiconductive properties to increase the efficiency of electron transfer. In this experiment, rhodium was used a second metal to be incorporated into a Cu3(BTC)2 MOF. Various temperatures and times were tested to optimize the amount of rhodium incorporated into the MOF. X-ray photoelectron spectroscopy (XPS) was used to calculate ratio of rhodium to copper which determined percent rhodium incorporated on the MOF. Through analysis of the inferential statistics on rhodium incorporated, it was shown that the treatments were significant (F(2,4)=43.24, p=0.013), however, time (F(5,4)=0.61, p=0.621) was not significant. A tukey test, showed that treatments 2 and 3 were significantly different than the control (treatment 1) as p<0.05. Though treatment 2 had a higher average rhodium percentage than treatment 3, a tukey test showed that there was no significant difference between the 3-2 as p=0.284. Based on the experimentation rhodium was successfully able to be integrated into the MOF structure forming a bimetallic CuRhBTC MOF.
