For comparison, pure silica SBA-15 and HPW were synthesized
according to the literature procedures;[5,42] conventional SBA-15
supported HPW was made by immersing SBA-15 powder into an
HPW solution for 3 h followed by drying at 100 °C for 24 h, and
then calcining at 300 °C for 5 h; this is denoted as HPW/SBA.

Characterization: Powder X-ray diffraction (XRD) data were re-
corded on a Siemens D5005 (30 kV, 30 mA) using nickel-filtered
Cu-Kα radiation with a wavelength of λ = 0.15418 nm, diffraction
patterns were collected under ambient conditions in the 2θ range
of 0.6–4° at a scanning rate of 0.6°/min and in the 2θ range of 4–
70° at a scanning rate of 6°/min. Transmission electron microscopy
(TEM) experiments were performed on a JEM-3010F electron
microscope (JEOL, Japan) with an acceleration voltage of 300 kV.
The nitrogen isotherms at the temperature of liquid nitrogen were
measured using a Micromeritics ASAP 2010M system. The samples
were outgassed for 10 h at 300 °C before the measurements. Infra-
red (IR ) spectroscopy was performed on a Bruker IFS 66v/S infra-
red spectrometer in the range 400–4000 cm–1 using KBr pellets in
vacuo (Ͻ0.4 Pa) at ambient temperature. The diffuse reflectance
UV/Visible spectra for powder samples were obtained on a Perkin–
Elmer Lambda 20 UV/Visible spectrometer equipped with an inte-

NMR experiments were performed with magic angle spinning
(MAS) on an Infinity Plus-400 spectrometer operating at a fre-
quency of 104.26 MHz, chemical shifts were referenced to 85%

were determined by the results of inductively-coupled plasma
analysis (ICP, Perkin–Elmer 3300DV).

Catalytic Cracking of Cumene and 1,3,5-Triisopropylbenzene
(TIPB): Catalytic cracking of cumene and 1,3,5-triisopropylben-
zene were carried out using the pulse technique in a micro-reactor,
and the analyses of the catalytic products were performed by gas
chromatography (GC-17A, Shimadzu Co.) equipped with a flame
ionization detector (FID). The catalytic cracking was performed
according to the following standard conditions: the reaction tem-
perature was 300 °C (no thermal cracking); the reaction pressure
was atmospheric pressure; the mass of the catalyst was 0.050 g;
0.2 μL of cumene or 1,3,5-triisopropylbenzene was injected for each
test; nitrogen was used as the carrier gas at a flow rate of 45 mL/
min.

Esterification of Acetic Acid with Ethanol and of Benzoic Acid with
tert-Butanol: The esterification of acetic acid with ethanol was per-
formed under nitrogen at 40 °C in a flask (50 mL) containing sus-
pended catalyst powder (60 mesh pass), acetic acid (0.15 mol), and
ethanol (0.15 mol), and with vigorous agitation for 4 h. The
amount of catalyst used was 0.10 g. The product esters were ana-
lyzed by gas chromatography (6890N, Agilent Co.) equipped with
a flame ionization detector (FID) with an HP-5 flexible quartz cap-
illary column (30 m in length).

The esterification of benzoic acid with tert-butanol was performed
under nitrogen at 80 °C in a flask (50 mL) containing suspended
catalyst powder (60 mesh pass), benzoic acid (5 mmol), and tert-
butanol (10 mmol), and with vigorous agitation for 5 h. The
amount of catalyst used was 0.10 g. The product esters were ana-
lyzed by gas chromatography (6890N, Agilent Co.) equipped with

illary column (30 m in length).
