What Types of Catalysts are Used in Biomass Conversion?
Catalysts used in biomass conversion can be broadly classified into heterogeneous and homogeneous catalysts. Heterogeneous catalysts, such as metal oxides, zeolites, and supported metal catalysts, are widely used due to their ease of separation and reusability. Homogeneous catalysts, including acids and organometallic complexes, offer high activity and selectivity but often pose challenges in catalyst recovery.
