Pretreatment of lignocellulose to break down the material into monosaccharides has been researched extensively for its potential for biofuel production due to the abundance of lignocellulosic biomass waste. Byproducts of this process can limit the yields of ethanol in bioreactors making other uses of the waste material worth exploring for technologies such as cheap functional polymeric materials. By adjusting these classic aqueous treatment methods and selecting the right metal ions and applying a drying and chemically reductive heat treatment a variety of porous carbohydrate-based polymeric materials were generated for different uses including oil cleanup, sensors and battery materials. These syntheses were studied in situ using UV-vis spectroscopy and strong base titration. Thermogravimetric analysis was used to study the reductive heat treatment step in the synthesis process. The solid structures and composition of generated polymeric materials were studied using FTIR, Raman and EDXA. SEM and HRTEM were used to study the microstructure of the materials. These materials were found to exhibit a variety of properties related to the metals they were produced with and the types of carbohydrates used to make them.
