A comparative study of the lattice structure, optical band gap, electrical conductivity and polarization at different stages of the heat treatment of chemical routed Al(OH)3

Effect of Cu and Sb active sites on the acid–base properties and reactivity of hydrated alumina for glycerol conversion by dehydrogenation and dehydration reactions

“…41,42 The band gap of the bulk alumina has a value near 8.7 eV, characteristic of an insulator material. 43 Therefore, the DRS for the Al sample points to the structure defects (amorphous) and hydroxyl groups on the surface, 44,45 consistent with the XRD profile presented in Fig. 1 and FT-IR spectra in Fig.…”

Synthesis of tetrazoles catalyzed by a new and recoverable nanocatalyst of cobalt on modified boehmite NPs with 1,3-bis(pyridin-3-ylmethyl)thiourea

“…Because organic reactions take place at temperatures lower than the BNPs phase change. Therefore, Boehmite nanomaterials have also attracted attention in absorbent, 27 coatings, 28 flame retardant, 29 optical material, 30 ceramics, 31 vaccine adjuvants, 32 cosmetic products, 2,33 pillared clays and sweep-flocculation for fresh water treatment. 13 Consequently, we investigated a new complex of cobalt with 1,3-bis(pyridin-3-ylmethyl)thiourea on boehmite nanoparticle (Co-(PYT) 2 @BNPs) as a reusable nanocatalyst in the synthesis of tetrazole derivatives.…”

A New Neodymium Complex on Boehmite Nanoparticles with 1,3‐Bis(pyridine‐3‐ylmethyl)thiourea as a Practical and Reusable Nanocatalyst for the Chemoselective Synthesis of Tetrazoles

“…[12,45,46] Also, boehmite NPs have several unique properties e. g. great surface area, easy availability, non-toxicity, and mechanical and thermal stability. [12,47] Boehmite nanomaterials have also attracted considerable attention in absorbent, [48] coatings, [49] ceramics, [50] flame retardants, [51] vaccine adjuvants, [52] optical material, [53] cosmetic products [54] and starting material for the synthesis of alumina. [55] Therefore, in continuation of our previous work that samarium metal was stabilized on boehmite nanoparticles, [56] in this work, we introduced a new catalyst of neodymium on modified boehmite nanoparticle (Nd-bis(PYT)@boehmite NPs) as a practical, stable, reusable and stable nanocatalyst in the homoselective synthesis of 5-substituted-1H-tetrazole derivatives.…”
