Recycling of the SILLP biocatalysts: CNTs-CONH-Oc₂PO₄ (A5) at 20 °C (blue), CNTs-CONH-Oc₂PO₄ (A5) at 40 °C (red), CNTs-CONH-Oc₂PO₄ (A5) at 60 °C (green), and CNTs-C=N-Oc₂PO₄ (I5) at 20 °C (yellow). Reaction conditions: 2-adamantanone 1 mmol (0.150 g), toluene 0.5 mL, n-octanoic acid 0.5 mL, 0.080 g of biocatalyst, 35% aq. H₂O₂ 2 mmol (0.194 g), 20–60 °C, 240 min at 20 °C; 90 min at 40 °C or 45 min at 60 °C, 400 rpm.
