Bimetallic Ru-(Cr, Ni, or Cu) and La-(Co or Mn) incorporated MCM-41 molecular sieves as catalysts for oxidation of aromatic hydrocarbons

Preparation of ceria-zirconia solid solution with enhanced oxygen storage capacity and redox performance

“…Similar adsorption-desorption isotherms with evident hysteresis looped at higher relative pressures P/P 0 were observed for all samples. They had typical porous frameworks belonging to type IV isotherms, which were characteristic of mesoporous materials with ink-bottle pores, as defined by IUPAC [15,17]. The samples prepared by UAMR exhibited adsorption volumes throughout the range of P/P 0 , which were higher than the corresponding samples fabricated by COP.…”

Oxidation of benzene over bimetallic Cu–Ce incorporated rice husk silica catalysts

“…Upon calcination at 773 K, these bands disappeared. This suggests only weak adsorption of organic molecules took place on the catalyst surface during oxidation reaction [56]. High activity of studied catalysts thus can be correlated to this weak adsorption and can be reused after removal of adsorbed species by proper heat treatment of reacted catalysts.…”

Synthesis of novel NO type bis(diazoimine)–metal complexes supported on mesoporous silica: Microwave assisted catalytic oxidation of cyclohexane, cyclooctane, cyclohexene and styrene

“…Functionalized organic or inorganic polymer supported ligand, metal complexes and their applications are one of the most studying and interesting subject for the scientists [24][25][26][27][28][29][30][31][32][33][34][35][36][37][38][39][40][41][42][43]. In the literature, there are a lot of solid supported ruthenium, iron, tungsten, manganese, cupper, cobalt, molybdenum and nickel complexes having different oxidation state [27][28][29][30][31][32][33][34][35][36][37][38][39][40][41][42][43].…”

“…Hence, it can be speculated that microwave power is very usable, easy and clean for organic and inorganic syntheses. Our silica-supported Cu(II) complexes showed the best selectivity for the oxidation of cyclohexane, cyclohexene, cyclooctane and Ni (II) complexes are the best catalysts for the oxidation of styrene under microwave power if compared the literature [9,10,12,13,[22][23][24]29,[30][31][32][33][34][35][36][37][38][39][40][41][42][43].…”
