Abstract

Growing demand for petroleum has been an ongoing issue that calls for the attention of the scientific community. To accommodate this demand, various types of renewable energy and chemical feedstock sources are being assessed to establish which can efficiently sustain this demand. One of the most sustainable natural resources is biomass. The utilization of biomass derived from lignin, a complex organic polymer which is one of the most abundant plant components, is the interest of the study. When broken down into simpler molecules, lignin could provide a more sustainable source of aromatic compounds, a major constituent of petroleum, and a building block of many synthetic materials. Due to the irregular nature of its cross-linking, lignin degradation has been more difficult to study in comparison to other forms of biomass, such as cellulose. To approach this issue, we have investigated a two-step catalytic process using molybdenum and copper complexes along with an oxidizing solvent. The identity and selectivity of the aromatic fragments produced were determined by proton nuclear magnetic resonance (1H NMR) spectroscopy and gas chromatography – mass spectroscopy (GC–MS) studies.
