a Substrate scope. b The conversion and reaction time of bulk and confined reactions of different alcohol substrates are compared. Bulk reaction condition: HTiNbO5-X nanosheets (10 mg), alcohol (0.2 M) and acetic anhydride (0.3 M) in CH3CN at 40 °C for 24 h. Confined reaction condition: HTiNbO5-X membrane (d = 11.0 Å), alcohol (0.2 M) and acetic anhydride (0.3 M) in CH3CN at 23 °C. Error bars represent standard deviation of three measurements.
