The synthesis of materials with tailored properties is one of the most active areas of material science [1, 2]. Among so many materials, γ-alumina due to the significant application in catalysis, electronic and ceramic industry has been studied extensively [3]. Various processes have been employed for the preparation of high quality alumina, including sol-gel processing from aluminum alkoxides....

The treatment of titanium alkoxides with 1,5-pentanedioxime or 2,5-hexanedioxime resulted in the formation of complexes [{TiL(OR)2}2] in which the dioximate ligands (L) bridge a dimeric Ti2(μ2-OR)2 unit. The structures of the complexes were determined by single-crystal structure analysis, ESI mass spectrometry, and 1D and 2D solution NMR spectroscopy. In contrast, the treatment of titanium alko...

Abstract A prime challenge in the development of new battery chemistries is fundamental understanding generation electrode–electrolyte interface (EEI) and its evolution upon cycling. Tip‐enhanced Raman spectroscopy (TERS) under an inert gas atmosphere employed to study chemical components anode/cathode electrolyte a sodium‐ion battery. After first cycle, TERS reveals that EEI mostly consists or...

This study reports the thermodynamics of bound species derived from ethene, propene, n-butene, and isobutene on solid acids with diverse strength and confining voids. Density functional theory (DFT) and kinetic data indicate that covalently bound alkoxides form C-C bonds in the kinetically relevant step for dimerization turnovers on protons within TON (0.57 nm) and MOR (0.67 nm) zeolitic channe...

The influence of the confinement imposed by eight different zeotypes on formation alkoxides 13 primary alcohols is studied using dispersion corrected density functional theory calculations with PBE-D3 functional. Adsorption energies are computed along barriers for alkoxides, which first step stepwise dehydration mechanism. We find that variations in adsorption and transition state largely gover...
