- •
Pd, Rh, and Rh-Pd nanoparticles are deposited on Aluminum powder via spontaneous redox reactions in aqueous solutions at room temperature.
- •
Aluminum supported metals, an easy preparation catalysts, used for aqueous phase polybrominated diphenyl ethers in sc-CO2.
- •
The conditions for hydrobromination are green, hydrodebrominating 4- and 4,4′-bromodiphenyl ethers into diphenyl ether in sc-CO2 below 100 °C.
- •
Hydrogenolysis of diphenyl ether producing cyclohexanol and cyclohexane is the minor reaction route.
