Approaches to the synthesis of heterogenised metalloporphyrins

Layered zeolitic materials: an approach to designing versatile functional solids

“…This is the case for the incorporation of heterogenized porphyrins and metaloporphyrins on robust solids such as purely siliceous ITQ-2 zeolites, generating active electrocatalysts for oxygen reduction processes with reduced activity lost due to the minimized desorption of active complexes. 137 Following this anchoring approach, Schiff bases complexes were stabilized onto MWW individual layers from ITQ-2 delaminated zeolites, generating active asymmetric catalysts for enantioselective epoxide ring opening reactions when grafted chromium salen complexes were incorporated. 138 Similarly, chiral delaminated ITQ-2 zeolites were formed by anchoring stabilized salen (Pd and Ni) complexes, being effectively used (TOFs around 200x10 3 h -1 ) to catalyze the hydrogenation of imines or alkenes, 139,140 and for Heck and Suzuki coupling reactions under phosphine-free conditions.…”

Electrochemical Studies of an Iron Porphyrin Immobilized on Nb2O5/SiO2 and Its Application for Simultaneous Determination of Dopamine and Ascorbic Acid Using Multivariate Calibration Methodology

“…The immobilization of metalloporphyrins is also associated with an easily recyclable solid, which can be reused [26]. Therefore, immobilized metalloporphyrins on different matrices surfaces such as clays [29], silica [30,31], zeolites [32,33] and glassy carbon [34] have been extensively used for the construction of modified electrodes for analytical determination of many different substrates, including dopamine and ascorbic acid [34 -36].…”

Synthesis of germanosilicate type CDS-1 zeolite with CDO topology and its zeolitic layered precursor

“…Among these materials, the PREFER (layered precursor of ferrierite) has been interestingly investigated [13][14][15][16][17], in particular, the delaminated PRE-FER (ITQ-6) [18,19] has applied for catalysts and novel supports as a nano-sheet silicate [20][21][22][23][24][25]. We have reported the synthesis of boron-containing [B]PLS-1 and [B]CDS-1 zeolite by dry gel conversion (DGC) method using layered silicate H-LDS which is structural resemblance of layered silicate kanemite [26][27][28], and recently reported the [Ga]PLS-1 and [Ga]CDS-1 zeolite applying on the methanol-to olefin (MTO) reaction as a solid acid catalyst [29].…”
