文摘
- •
Stearic acid deoxygenation under inert conditions is a route to ‘green diesel’.
- •
Benchmark Pd/C catalyst gives ∼70% yields but unmodified silica gives yields <25%.
- •
Low performance of silica shown not to arise from Pd dispersion.
- •
Silica modified with phenyl and amine groups gives high dispersion and yields >85%.
- •
Organosilane modifications demonstrated to strongly impact supported metal catalysis.
