General procedure: Typically, the required amount of catalyst (0.037 mmol of Zr)was added to a round-bottom flask (25 mL). To remove absorbedwater in the catalysts, the MOFs were pre-treated by heating themat 150C under vacuum overnight. The required amount of alco-hol was introduced (5 mL) into the flask and the system sonicatedfor 15 min. After this time, the epoxide was added (1 mmol). Sub-sequently, the reaction mixture was placed in a preheated bath bathat the required temperature (i.e. 50C) and stirred magnetically.In the case of amine after the activation of the catalyst, acetoni-trile (2.5 mL) was added as solvent, the catalyst was sonicated andfinally, the amine (1.0 mmol) and the styrene oxide (1.0 mmol)were added. At the end of the reaction the catalyst was exhaustivelywashed with methanol to recover most of the adsorbed product.Product isolation was carried out by purification with flash col-umn chromatography on silica gel using hexane: dichloromethaneas eluent. The course of the reaction was periodically followed byextracting aliquots of the reaction mixture with a syringe, dilutingin methanol and injecting the mixture immediately in GC (6890Network GC system Agilent technologies) and using a calibrationplot to determine the product concentration.

In this example, a Zn-ligand complex 1 was synthesized via the following reaction: Into a 100 mL reaction bottle was prepared and, in a low temperature inert environment, hexane (20.0 mL) was added, then a 1.0 M ZnEt2/hexane solution (10.0 mL) was added, and then CH3OCH2C(CH3)2OH ligand (1.16 mL) was added. The resulting mixture was reacted at 0 C. for about 2 hours. Next, the resulting solution was added with DPM (dipivaloylmethane) (2.0 mL) at a low temperature, and the reaction was continued for 3 hours. Next, the solution was dried to obtain a white solid product 1 with a yield >98%. 1H NMR, C6D6, 200 MHz: 5.84 (s, 1H), 3.06 (s, 3H), 2.94 (s, 2H), 1.23 (s, 18H), 1.11 (s, 6H). The complex 1 was subjected to a thermogravimetric analysis (TGA) at a heating rate of 10 C./min, and the result indicates that the complex 1 has a thermal pyrolysis temperature of about 148 C. in air.

After the reaction has ended, the precipitate is filtered off and the solvent is distilled off via a Vigreux column, and the residue is distilled at standard pressure, yielding the title compound: 1 -H-NMR (200 MHz; CDCl3)=3.33/s (3H); 3.15/s (2H); 1.13/s (6H).

EXAMPLE 10 A 500 mL, five-necked, glass flask was equipped with a dropping funnel, a reflux condenser, a thermometer and a stirrer, followed by replacing the inside atmosphere of the flask with nitrogen. This flask was charged with 200.0 g (428 mmol) of a tetrakis(diethylamido)hafnium Hf[N(C2H5)2]4 containing 1,000 wtppm of zirconium, followed by cooling to 0 C. and then adding 21.2 g (208 mmol) of trifluoromethanesulfonic acid CF3SO3H from the dropping funnel in dropwise manner by spending 1 hr. After the dropping, the temperature was increased to 20 C. with stirring for 1 hr.This reaction solution was distilled under a condition of 125 C. and 0.12 kPa, thereby obtaining 134.2 g of a fraction. The obtained fraction was found by 1HNMR to contain tetrakis(diethylamido)hafnium Hf[N(C2H5)2]4 as a main component. It was found by an ICP atomic emission spectrometer that zirconium concentration of the fraction was 137 wtppm. It was found by ion chromatography that trifluoromethanesulfonic acid ion concentration of the fraction was 2.0 wt %. A bottom residue after the distillation was in 68.5 g and had a zirconium concentration of 1,884 wtppm and a trifluoromethanesulfonic acid ion concentration of 29.0 wt %.Then, 130 g of the obtained fraction was put into a 500 mL, five-necked, glass flask equipped with a dropping funnel, a reflux condenser, a thermometer and a stirrer, followed by cooling to 0 C. and then adding 20.1 g (134 mmol) of trifluoromethanesulfonic acid CF3SO3H from the dropping funnel in dropwise manner by spending 1 hr. After the dropping, the temperature was increased to 20 C. with stirring for 1 hr.This reaction solution was distilled under a condition of 125 C. and 0.12 kPa, thereby obtaining 86.9 g of a fraction. The obtained fraction was found by 1HNMR to contain tetrakis(diethylamido)hafnium Hf[N(C2H5)2]4 as a main component. It was found by an ICP atomic emission spectrometer that zirconium concentration of the fraction was 18 wtppm. It was found by ion chromatography that trifluoromethanesulfonic acid ion concentration of the fraction was 2.1 wt %. A bottom residue after the distillation was in 45.4 g and had a zirconium concentration of 355 wtppm and a trifluoromethanesulfonic acid ion concentration of 46.3 wt %.Then, 80.0 g of the obtained fraction was put into a 500 mL, five-necked, glass flask equipped with a reflux condenser, a thermometer and a stirrer, followed by adding 2.0 g (26 mmol) of lithium diethylamide LiN(C2H5)2 and then stirring at 25 C. for 1 hr. Then, this reaction solution was distilled under a condition of 125 C. and 0.12 kPa, thereby obtaining 76.3 g of a fraction. The obtained fraction was found by 1HNMR to be tetrakis(diethylamido)hafnium Hf[N(C2H5)2]4. Zirconium concentration of the fraction was 18 wtppm, and trifluoromethanesulfonic acid ion concentration of the fraction was less than 10 wtppm (detection limit). A bottom residue after the distillation was in 5.5 g and had a zirconium concentration of 30 wtppm and a trifluoromethanesulfonic acid ion concentration of 6.8 wt %.Then, 70.0 g of the obtained fraction (tetrakis(diethylamido)hafnium) was put into a 500 mL, five-necked, glass flask equipped with a dropping funnel, a reflux condenser, a thermometer and a stirrer, followed by cooling to 0 C. and then adding 93.6 g (900 mmol) of 1-methoxy-2-methyl-2-propanol C5H12O2 from the dropping funnel in dropwise manner by spending 1 hr. After the dropping, the temperature was increased to 20 C. with stirring for 1 hr.This reaction solution was distilled under a condition of 135 C. and 1.33 Pa, thereby obtaining 84.2 g of a fraction. The obtained fraction was found by 1HNMR to be tetrakis(1-methoxy-2-methyl-2-propanolato)hafnium Hf(C5H11O2)4. It was found by an ICP atomic emission spectrometer that zirconium concentration of the fraction was 18 wtppm.

2.4. Assessment the photocatalytic performance of the CdS/g-C3N4/4AZcomposite
The aqueous solution of cefoperazone (CFP) was chosen as themodel effluent to investigate the photocatalytic performance ofthe synthesized CdS/g-C3N4/4AZ nanocomposite under visible lightirradiation. A 300 W halogen lamp (OSRAM, Germany) wasselected as a visible light source with a glass optical filter for cutoff the components with k > 420 nm. In each experiment, thedesired amount of the as-synthesized ternary composite wasadded to the 100 mL of the CFP solution with a specified concentrationand pH value. Before starting each run, to establish the adsorption/desorption equilibrium, the antibiotic-photocatalyst mixturewas magnetically stirred in the dark for 60 min. The pH of the solutionwas adjusted using NaOH and HCl solutions with a concentrationof 0.1 M. At specific time intervals, 5 mL of the solution wasextracted from photo-reactor and the residual amount of CFPantibiotic was measured spectrophotometrically using a singlebeam spectrophotometer (Shimadzu UV- Mini-1240) at kmax = 229-nm. Eq. (1) was used to calculate the degradation percentages ofthe CFP.In this equation, [CFP]0 and [CFP]t represent the initial andresidual concentration of the CFP in the solution (mg L-1),respectively.To probe the degradation mechanism of the CFP in the photocatalyticprocess, the effect of the addition of the three differentscavengers, including isopropanol (IPA), benzoquinone (BQ), andsodium oxalate (NaOx) was investigated on the degradationperformance.An Agilent 6890 gas chromatograph with a 30 m to 0.25 mmHP-5MS capillary column along with an Agilent 5973 mass spectrometer(Canada) was applied to determine the produced intermediatesfrom photodecomposition of CFP.
