- Direct integration with downstream processes
- Highly tunable reaction parameters
Background:
Hydrogen peroxide is a vital industrial oxidant essential for downstream catalytic processes like alkene epoxidation. Current production relies on the anthraquinone process, requiring resource-intensive, separate synthesis and purification steps. Additionally, conventional direct synthesis is restricted to protic solvents to enable proton-coupled electron transfer, preventing integration with organic oxidations requiring aprotic environments. A need exists for continuous, direct synthesis methods that integrate seamlessly into these applications to streamline production.
Technology Overview:
Scientists at Berkeley Lab have developed a method for the continuous synthesis of hydrogen peroxide directly from hydrogen and oxygen in aprotic solvents. This technology utilizes heterogeneous metal catalysts paired with dissolved acid-base pairs that act as proton shuttles. These shuttles facilitate proton-coupled electron transfer pathways, enabling continuous generation.
Unlike the conventional anthraquinone process or methods requiring protic solvents, this approach is tunable and uses easily separable catalysts. An advantage is direct integration with downstream catalytic oxidations, like sulfoxidation and alkene epoxidation, eliminating separate synthesis, purification, and storage steps. In tests, the palladium catalyst yielded > 6 mM of hydrogen peroxide in 1.5 hours.
