摘要

Cobalt(II) dithiocarbazate-silane complex [3APTES + AQSMDTC@Co(II) complex] was synthesized using a newly developed Schiff base (SB) ligand derived from acenaphthoquinone (AQ), S-methyldithiocarbazate (MDTC), and (3-aminopropyl)triethoxysilane (3APTES), together with cobalt(II) acetate salt. The Co(II)-MSNs [MCM 41@AQSMDTC@Co(II) complex] was fabricated by MCM 41 on the cobalt(II) dithiocarbazate-silane complex. The new confirmation of the complex was extensively characterized using various analytical techniques. FT-IR was used to confirm the formation of thione-thiol, while SEM-EDX was employed to assess surface morphology and elemental composition. TEM analyses revealed a hexagonal morphology and an average particle size distribution of 14 nm for MCM-41 and 12 nm for the Co(II)-MSNs complex. PXRD was utilized to identify the 2θ reflections corresponding to d100, d110, and d200. Additionally, TGA indicated that the residue mass of MCM-41 is 89 wt%, while the Co(II)-MSNs complex has a residue mass of 88.5 wt%. N2 absorption-desorption measurements showed that Co(II)-MSNs have a surface area of 411 m²/g, a pore volume of 0.213 cm³/g, and a pore size of 13 nm, compared to MCM-41. Additionally, the heterogeneous catalyst was monitored for catecholase (Cat-ox) activity using UV-Vis spectroscopy, which involves the conversion of 3,5-di-tert-butylcatechol (3,5-DTBC) to 3,5-di-tert-butylquinone (3,5-DTBQ). The Co(II)-MSNs could be recovered and reused without significantly losing their catalytic ability.
