Funds were requested to support one student, Luis Perez, to investigate the development of sol-gel based materials containing graphene oxide (GO) and tetrapropylorthotitanate (TPOT) with and without silver-nanoparticles (NP) as possible chemical sensors by observing surface enhanced Raman spectroscopic (SERS) changes in graphene oxide or reduced graphene trapped within the materials. This project builds upon my previous research involving the development of new host materials for chemically active dyes that can be used as sensors. The goals of this project were threefold: to determine 1) if new sol-gel materials can be synthesized containing TiO2 formed from TPOT or Degussa P25 TiO2 nanoparticles, 2) are the materials conductive when they also contain GO or thermally reduced GO, and 3) are there spectroscopic changes that can be detected by SERS leading to possible sensor applications.


This research was conducted as part of a Linfield College Student-Faculty Collaborative Research Grant in 2017, funded by the Office of Academic Affairs.
