Effect of Synthetic Route and Metal Oxide Promoter on Cobalt-Based Catalysts for Fischer–Tropsch Synthesis

Synthesis and crystal structure of a new copper (II) complex, designed to produce efficient successor of Cu2O, toward synergy of adsorption and photodegradation of MB

“…(iv) The catalytic activity of synthetic catalysts is morphology dependent. As mentioned in the previous section, the preparation of catalysts through thermolysis of Cu complex lead to creating some features such as high active phase dispersion, small particle size and high specific surface area 74–76 . By increasing the specific surface area of a catalyst, more active sites will be available for adsorption of MB and followed by degradation of dye, enhancing the photodegradation of the catalyst.…”

“…As mentioned in the previous section, the preparation of catalysts through thermolysis of Cu complex lead to creating some features such as high active phase dispersion, small particle size and high specific surface area. [74][75][76] By increasing the specific surface area of a catalyst, more active sites will be available for adsorption of MB and followed by degradation of dye, enhancing the photodegradation of the catalyst. On the other hand, by increasing the photodegradation of the adsorbed contaminant on the surface of catalyst, adsorption increases.…”

A comparative study of micro- and nano-structured di-nuclear Co(II) complex, designed to produce efficient nano-sorbent of Co3O4 applicable in the removal of Pb2+

“…The preparation method plays an important role in the performance and activity of the catalysts, because it can affect the physicochemical properties of the catalysts. As mentioned in the previous section, the preparation of Co 3 O 4 -uc and Co 3 O 4 -hc through thermolysis of dinuclear inorganic complex lead to creating some features such as high active phase dispersion, small particle size and high specific surface area [38,39]. However, adsorption efficiency can be affected by several parameters such as particles size, BET surface area, and crystalline phase.…”

“…The results of their studies have shown that nanoparticles prepared by thermal decomposition of the inorganic complex have higher catalytic performance than the catalysts which prepared by other methods, such as impregnation and co-precipitation. The use of the inorganic complex as precursor for the preparation of nanoparticles potentially provides many advantages as a new route since: (a) the nanoparticles which obtained by thermolysis of inorganic complexes have high catalytic performance due to thier high surface area and small particle size [38,39], (b) the intimate metal contact in the synthesized complexes causes their homogeneous dispersion in the catalyst structure [40]. In this study, for the first time, an effective Co 3 O 4 nanosorbent was prepared by the thermal decomposition of a binuclear inorganic complex through the following steps.…”

Synthesis new Co–Mn mixed oxide catalyst for the production of light olefins by tuning the catalyst structure

“…This method significantly optimizes the catalyst's physicochemical properties. [23][24][25][26][27][28] Herein, [Co Synthesis of Co-Mn/Al 2 O 3 catalyst (thereinafter CMS): An aqueous solution containing 3.9 g of compound 1 was mixed by 0.6 g of alumina (Sasol). The mixture was stirred at 80 C in a rotary evaporator for 5 h. The inorganic precursor was obtained by filtration and dried in oven at 100 C for 10 h, followed by calcinations at 600 C at the atmosphere of static air in an electric furnace for 6 h.…”
