specifically capture glycoproteins, showing a higher selectivity and better dynamic
binding capacity towards horseradish peroxidase and transferrin (Fig. 3.36). The
resulting affinity monolithic column has been successfully employed to specifically
capture transferrin from a bovine serum sample [124]. Fe-BTC gel was also employed
as a porogen to prepare molecular imprinting polymer [125]. The resulting molecularly imprinted polymer has greater-specific surface areas and can be used to identify
the levofloxacin in the water with high efficiency.
A gel of 90 and AgNO 3 forms in the presence of N,N′-methylenebisacrylamide
(MBA), acrylic acid (AAc) and benzoyl peroxide in THF [126]. The hybrid gel is
heated at 63 °C to carry out the radical copolymerization of MBA and AAc, and the
gel template is removed by excess ammonia to get P(MBA-AAc) 1D nanostructures
(Fig. 3.37). The hybrid gel can also be heated at 120 °C to reduce Ag
+ ions to
obtain Ag nanoparticles-loaded P(MBA-AAc) nanowires. The nanowires effectively catalyze the photodegradation of methylene blue. The photodegradation of
methylene blue is pH-responsive, and the rate at pH 7 is almost four times than that
at pH 2.2.
Hierarchically porous carbons can be obtained through metal–organic gel templates [127]. Casted Al-BTC xerogel has hierarchical micro-meso-macro porous
architectures (Fig. 3.38) with ultrahigh surface areas (3770 m
2 g
−1
), considerable
hydrogen uptake (2.98 wt%) and quite large pore volume (2.62 cm
3 g
−1 ). It can be
used as cathode material after sulphur impregnation for lithium–sulphur battery,
showing a discharge capacity of 1240 mA h g
−1 (74% of 1675 mA h g
−1 the
theoretical value) at the 2nd cycle. Simple pyrolysis of polypyrrole-doped Al-based
metal–organic gel at 800 °C produces nitrogen-doped porous carbon material
(N@MOG-C) with high surface area of 1542.6 m
2 g
−1 and large pore volume of
0.76 cm
3 g
−1 . The N@MOG-C-modified electrode is able to detect Cd
2+ ions
present in concentrations of 0.025–5 lmol L
−1 , with a detection limit of
2.2 lmol L
−1 [128].
