Cobalt-Nanoparticles Supported on Mesoporous Silica Intercalated Hydrotalcite (Co-MgAl-HT-SBA) Prospective Catalysts for Hydroformylation

Progress on layered hydrotalcite (HT) materials as potential support and catalytic materials

“…Baskaran et al later utilized silicate intercalated HT both as a support to disperse cobalt nanoparticles and for hydroformylation reaction. 191 The cobalt nanoparticles range of 1-15 wt% loaded in the SBA-15 intercalated MgAl-HT composites (MSB) support. Their HR-TEM analysis showed uniform spherical cobalt nanoparticles in the range of 3-10 nm.…”

Framework of ruthenium-containing nickel hydrotalcite-type material: preparation, characterisation, and its catalytic application

“…These materials can be used either in the as-synthesised form or in the form of mixed metal oxides derived aer calcination. [1][2][3][4][6][7][8][9][10][11][12][13][14] These types of layered HT materials possess inherent basicity and have redox properties, which are derived from the elemental composition of the octahedral layers of the materials. Catalytic properties of HTs can be modied by introducing varying divalent and trivalent cations such as Zn 2+ , Ni 2+ , Mn 2+ , Co 2+ , Fe 2+ , Cr 3+ , Fe 3+ , Mn 3+ , Co 3+ , and Ga 3+ into the framework.…”

“…Nickelbased HT was developed because it is easily available, low-cost alternative to noble metal catalysts, has electronic properties similar to noble metals, and has an excellent activity for various elementary organic transformations and reforming processes. [3][4][5][6][7][8][9][10][11][12][13][14][15] There are several studies on nickel-based HT-like catalyst for use in both ne, petro chemical and electrochemical processes such as catalytic reforming, dehydrogenation, hydrogenation, and electrocatalysis. 23 In recent years, attention has been focussed on the preparation and applications of monometallic HT-like compounds in which a single element (transition metal ions) was used in both divalent and trivalent framework sites.…”
