Amine‐Functionalised Hexagonal Mesoporous Silica as Support for Copper(II) Acetylacetonate Catalyst

Abstract

Copper(II) acetylacetonate was anchored onto a hexagonal mesoporous silica (HMS) material using a two-step procedure: (i) functionalisation of the surface hydroxy groups with (3-aminopropyl)triethoxysilane (AMPTSi) and then (ii) anchoring of the copper(II) complex through Schiff condensation with free amine groups, using two different metal complex loadings. Upon the first step, nitrogen elemental analysis, XPS and DRIFT showed the presence of amine groups on the surface of the HMS material, and porosimetry indicated that the structure of the mesoporous material remained unchanged, although a slight decrease in surface area was observed. Atomic absorption, XPS and DRIFT showed that copper(II) acetylacetonate was anchored onto the amine-functionalised HMS by Schiff condensation between the free amine groups and the carbonyl groups of the copper(II) com-

Synthesis, Characterization and Drug Release Capability of New Cost Effective Mesoporous Silica Nano Particle for Ibuprofen Drug Delivery

“…Then the filtrate is tested for ibuprofen loading UV-visible spectrophotometer at 264 nm. The collected drug-loaded MSN's were dried overnight at RT then pressed into 0.3 g disks (13 × 3 mm 2 in size) using uniaxial pressure (5.0 MPa) for drug release experiments [3].…”

“…1 ml aliquots of the samples were withdrawn at fixed sampling times and the same quantity was replaced immediately [3]. The withdrawn sample was then filtered through a 0.1 μm filter and suitably diluted before quantifying.…”

“…Following up these lots of materials with meso structures were synthesized like SBA family, MSU (MSUs) family [3], FSMs family [4] and KIT [5] were invented by various groups. They made attracted by scientist by their exclusive properties such as ordered and easily tunable pore structure, pore volume and surface morphology, and find applications in various applications such as catalysis, adsorption, separation, purification science and as a template for synthesizing other mesoporous material such as mesoporous carbon [6][7][8][9][10].…”

A relevante potencialidade dos centros básicos nitrogenados disponíveis em polímeros inorgânicos e biopolímeros na remoção catiônica

“…A inclusão de átomos de nitrogênio em cadeia cíclica de pirazina também dá flexibilidade às moléculas pendentes ligadas covalentemente na estrutura polimérica da sílica 21 . (9) A reatividade do grupo amino pode também ser evidenciada quando da reação com 3-bromopentanodiona para imobilizar o agente quelante β-dicetoamina 22 , como ilustrado na Equação 10, na reação direta com o complexo de cobre com acetilacetona 23 ou através da reação de imobilização da molécula 2-mercaptobenzotiazol, em presença de formaldeído 24 . Fato marcante é a reação de imobilização do herbicida picloram que, além de diminuir a toxidez da microbiota do solo, age também no decréscimo da biodegradação, porém, tem ainda a capacidade de complexar cátions [25][26][27][28] .…”

High Selective Oxidation of Alcohols Based on Trivalent Ion (Cr3+and Co3+) Complexes Anchored on MCM-41 as Heterogeneous Catalysts

“…The anchoring of acetylacetonate (acac) complexes such as Co(acac) 2 , Mn(acac) 2 and Cu(acac) 2 onto the surface of amine functionalized MCM-41 has already been reported previously. [21][22][23] This work reports the successful anchoring of Cr(acac) 3 and Co(acac) 3 onto MCM-41 channels.…”
