You will be shown an abstract from a materials science research paper. Your task is to extract all synthesis operations described in the abstract into a structured JSON format. Your output should be a JSON array. Each entry in the array should be a JSON object describing a single synthesis operation. This object should have the following fields:

- "trigger": A verbal predicate indicating a synthesis operation. This should be a string extracted directly from the abstract.
- "arguments": An array of arguments specifying aspects of the synthesis operation. Each entry in the array should be a length-2 array formatted as [<argument_text>, <argument_type>]. The `argument_text` should be a string extracted directly from the abstract. The `argument_type` should be one of the following types: ["Recipe_Precursor", "Atmospheric_Material", "Participant_Material", "Recipe_Target", "Solvent_Material"].

For instance, suppose an excerpt from the abstract reads:

Tetraethoxysilane (TEOS, 98%) and cetyltrimethylammonium bromide (CTAB, 98%) were purchased from Fluka. The MTTZ-siloxy derivative (triethoxysilyl-propyl-5-mercapto-1-methyl-tetrazole) was synthesized as previously described [38].

This excerpt includes two operations, which could be annotated as follows.

[{"arguments": [["Tetraethoxysilane", "Recipe_Precursor"], ["cetyltrimethylammonium bromide", "Recipe_Precursor"]], "trigger": "purchased"}, {"arguments": [["MTTZ-siloxy derivative", "Recipe_Target"]], "trigger": "synthesized"}]

In your response, please include the JSON and no other text.

Catalytic consequences of micropore topology, mesoporosity, and acidity on the hydrolysis of sucrose over zeolite catalysts
The conventional microporous FER, MFI, MOR, BEA, and FAU with different acidity (Si/Al ratio) were purchased from Zeolyst. MWW and PMWW were derived from the same precursor, MWW (P). The hydrothermal synthesis of MWW (P) was carried out by using the method described by Corma et al.39,40 One portion of the crystalline product MWW (P) was dried and calcined to produce MWW. The other portion of MWW (P) was swollen according to the method developed by Maheshwari et al.,41 followed by pillaring of the swollen materials using the procedure reported by Barth et al.38 The resulting solid was treated using the same conditions as those for MWW to produce PMWW. A multilamellar MFI was synthesized using the method reported by Ryoo and co-workers,43 through a coherent assembly of the zeolite layer and the structure directing agent, a diquaternary ammonium surfactant with a relatively long hydrocarbon chain. Pillaring of multilamellar MFI was done as reported by Na et al.42 to produce PMFI, using a similar pillaring procedure to that of swollen MWW (P). The as-synthesized MWW and MFI zeolites were ion-exchanged four times using 1 mol L-1 aqueous NH4NO3 (weight ratio of zeolite to NH4NO3 solution = 1:10) at 353 K for 12 h and subsequently collected by vacuum filtration, washed with deionized (DI) water three times, and dried at 343 K overnight. No ion-exchange process was applied to the commercial zeolites since they were purchased in the NH4+-form. All zeolite samples in their NH4+-form were treated in dry air (100 mL min-1, ultrapure, Airgas) by increasing the temperature from ambient temperature to 823 K at 1.45 K min-1 and holding for 4 h to thermally decompose NH4+ to NH3 and H+. To differentiate the same type of zeolite with different Si/Al ratios, each catalyst is named by its structure type and Si/Al ratio in the remainder of this paper.
