Better by design: nanoengineered macroporous hydrotalcites for enhanced catalytic biodiesel production

Templated, macroporous Mg-Al hydrotalcites synthesised viaalkali-free co-precipitation exhibit superior performance in the transesterification of C sub(4)-C sub(18) triglycerides for biodiesel production, with rate-enhancement increasing with alkyl chain length. Promotion reflects improved diffusion...

Zusammenfassung:Templated, macroporous Mg-Al hydrotalcites synthesised viaalkali-free co-precipitation exhibit superior performance in the transesterification of C sub(4)-C sub(18) triglycerides for biodiesel production, with rate-enhancement increasing with alkyl chain length. Promotion reflects improved diffusion of bulky triglycerides and accessibility of active sites within the hierarchical macropore-micropore architecture.
