the Minnesota NMR Center and in particular Dr. Gopinath Tata for
performing the Solid-state NMR experiments.
Catalytic evaluation of UiO-66: The catalytic reactions of UiO-66 were
carried out at 90 oC. In a typical reaction, 7 mg of catalyst, 5 mL of solvent
and 0.04 g of D-glucose were added into a 20-mL thick-walled glass
reactor and sealed with a crimp top (PTFE/silicone septum) from VWR.
The reactor was placed in an oil bath. At specific reaction times, the reactor
was quenched in an ice bath, and samples were collected. For the
hydrolysis step, the catalyst was filtered out of the solution, and deionized
water (5.00 g) was added to the solution, reacting for 24 h at 90 oC. The
samples were analyzed by HPLC with a Bio-rad Aminex HPX87C (300 X
7.8 mm) column and refractive index detector. The mobile phase was
ultrapure water (ph = 7.0) at 0.6 mL min-1, and the column temperature
was 80 oC.

Isotopic labeling experiments: In the isotopic labeling experiments,
reactions were conducted at 90 oC using either D- [13C-C1, 1H-C2] or D-
[13C-C1, 2H-C2]-glucose solutions for 24 h. The collected samples were
evaporated in a rotavap and further dissolved in D2O for nuclear magnetic
resonance (NMR) measurements. 1H NMR (32 scans) and 13C NMR (512
scans) spectra were collected using a Bruker 400 MHz NMR spectrometer.

Liquid adsorption experiments: A typical adsorption experiment involved
mixing 10 mg of MOF with 250 µL of sugar solution (ranging from 0.01 to
1 wt%). The mixture was stirred for 24 h at 40 oC followed by filtration (0.2
µm filter) for MOF removal. The amount of sugar present in solution after
adsorption was determined by HPLC. The adsorption capacity (q, mg/g)

13C Solid-state NMR experiments: Around 30 mg of MOF were mixed with
750 µL of 0.5 wt% sugar solution in 1-PrOH. The mixture was stirred for
24 h at 40 oC, followed by centrifugation to separate the solid from the
sugar solution. The powder was let to dry at room temperature overnight.

Solid-state, magic angle spinning nuclear magnetic resonance (MAS-
NMR) measurements were performed using a Bruker Avance 700 MHz
spectrometer equipped with an 11.7 T magnet and a Bruker 3.2 mm MAS
probe. Samples of 30 mg powder were packed into 3.2 mm ZrO2 rotors
and spun at 10kHz for MAS experiments. 13C MAS-NMR (operating
frequency 125.5 MHz) spectra were obtained with a recycle delay time of
5 s, and 10000 scans were accumulated for each sample. The CP transfer
was achieved by fulfilling the Hartmann− Hahn matching condition. The
first 1H 90° pulse was set to 5 μs. Finally, 1H 64-step small phase
incremental alternation (SPINAL-64)68 decoupling was implemented
during the acquisition period of the 13C NMR spectrum. The 13C chemical
shifts were referenced to carbon signals in TMS.
