Rationally designed Fe-MCM-41 by protein size to enhance lipase immobilization, catalytic efficiency and performance

Catalytic behavior of surfactant-containing-MCM-41 mesoporous materials for cycloaddition of 4-nitrophenyl azide

“…The lack of hydrothermal stability of the mesoporous materials has been overcome by the incorporation of heteroatoms such as Al, Ga, Ti, Fe, V, W and Cr [4][5][6][7]. These properties allow these mesoporous materials to be used in a wide range of applications such as catalysis [4][5][6][7], adsorption [8,10], extraction [11], energy [12], drug delivery systems [13], and for their luminescent character [14].…”

Preparation and catalytic performance of a novel highly dispersed bifunctional catalyst Pt@Fe-MCM-41

“…On the contrary, there are two obvious absorption peaks appearing at 218 nm and 251 nm in the 0.3% Pt@x% Fe-MCM-41 sample spectra, which may be caused by low-energy chargetransfer transitions of Fe 3+ / O 2À (tetrahedron lattice). 26,27 This absorption band proves that Fe 3+ has been introduced into the framework of the molecular sieve and is highly dispersed with tetrahedral coordination in the MCM-41 skeleton. Moreover, the radius ratio of Fe/O 2À is in the range of 0.214-0.4.…”

Modification of magnetic nanoparticle lipase designs for biodiesel production from palm oil

“…Magnetic nanoparticle immobilization of various enzymes e.g. laccase, α-amylase, β-galactosidase, and lipase also provides a large reactive surface area [13][14][15], and can improve enzyme stability [16]. Several forms of magnetic materials and covalent attachment methods have been tested for preparation of immobilized lipases using different designs, which provide immobilized enzymes that vary in their catalytic performance in aqueous and non-aqueous reactions.…”
