Flake-like tea-leaf-templated magnesium oxide for carbon dioxide adsorption.

Flake-like mesoporous magnesium oxide (MgO-TLT) was prepared using a bio-templating method with tea leaves (TLTs) as the template. MgO-TLT exhibited smaller crystallites (7.52 nm) than MgO prepared using the thermal decomposition method (22.52 nm). These smaller crystallites led to more structural d...

MgO-TLT exhibited smaller crystallites (7.52 nm) than MgO prepared using the thermal decomposition method (22.52 nm).
