Transition metal-modified mesoporous Mg-Al mixed oxides: Stable base catalysts for the synthesis of diethyl carbonate from ethyl carbamate and ethanol

- Tunable basicity of calcined hydrotalcites with mesoporous structure obtained by modifying with transition metal cations.
- Effective synthesis of diethyl carbonate achieved over Mn2+ modified calcined hydrotalcites.
- Good correlation between catalytic activity and both moderate and strong basicity.
- Mn2+ modified calcined hydrotalcites presented high catalytic stability.
