Gas phase acetone self-condensation over unsupported and supported Mg-Zr mixed-oxides catalysts

- Acetone self-condensation can be tuned for yielding C6 or C9 adducts.
- Mg-Zr mixed oxide is an effective catalyst for this reaction.
- Dispersion on non-microporous carbons increases their performance.
- Not only basic sites, but also acid sites play a key role in reaction mechanisms.
