Precursor Selection for Sol‐Gel Synthesis of Titanium Carbide Nanopowders by a New Intuitionistic Fuzzy Multi‐Attribute Group Decision‐Making Model

Abstract: This article develops a new intuitionistic fuzzy multi-attribute group decision-making model to solve precursor selection problems. The proposed model is based on a hybridization of intuitionistic fuzzy sets theory, grey relational analysis and technique for order performance by similarity to ideal solution method. To better describe the uncertain decision environment, multi-attribute group decision-making method with completely unknown weights of both experts and attributes is proposed in an intuitionistic fu… Show more

“…15 The selection of precursors for sol-gel synthesis remains a matter of current interest. 16 While 1 H NMR spectroscopy is doubtlessly the most powerful technique to characterize H-containing species and determine their structures in solution, this technique has been reported to be inconvenient for characterizing precursor solutions of alkoxides in the sol-gel process. 17 Occasionally, 1 H NMR and 13 C NMR spectroscopy have been used to support structures of titanium heterometallic oxo-alkoxy compounds.…”

“…The final macroporous structure and mechanical properties of alumina monoliths are influenced not only by the manufacturing methods but also by the simultaneous effects of different preparation parameters. Consequently, both processing of macroporous alumina with tailored porosity and the effects of different preparation parameters on porosity structure are of great importance 16,17 …”

“…The recent years have shown a rise in the number of studies that aim to synthesize MA with high specific surface area, large pore volume, and highly uniform pore size distribution owing to its high potential applications in such areas as membrane separation, catalysis, adsorption, and sensing . In the group of these studies, the sol‐gel based technique assisted by block copolymer as nonionic surfactant has been expanded to be an outstandingly interesting because this method allows to get high surface area MA with the possibility of tuning the porosity and surface properties . In this procedure, the strict experimental control of the parameters is notably important to obtain high surface area MA because the formed mesoporous structures can easily collapse during the solvent evaporation owing to the rapid rates of hydrolysis and condensation of alumina precursors and the existence of tremendous differences in the interactions among all precursors .…”
