Fast catalytic conversion of diethylene glycol to morpholine over thermally stable Zn promoted Cu-NiO/Al 2 O 3 catalyst prepared via combustion approach

Boron Modified Cu/Al2O3 Catalysts for the Selective Reductive Amination of Levulinic Acid to N‐Substituted Pyrrolidinones

“…Highly dispersed Cu-based catalysts with small particle size were deemed to possess excellent catalytic performance. [20,30] The well-dispersed Cu nanoparticles on the catalyst could provide more active sites and improve the contact efficiency of hydrogenation to generate target N-substituted-5-methyl-2-pyrrolidinones. According to the characterization results, the promotion of Cu dispersion and the reduction of Cu nanoparticles size were found in all boron modified Cu/Al 2 O 3 catalysts.…”

Hydrodesulfurization of dibenzothiophene using Pd-promoted Co–Mo/Al2O3and Ni–Mo/Al2O3catalysts coupled with ionic liquids at ambient operating conditions

“…Fig. 3A shows strong peaks for Al 2 O 3 at 2q of 47 and 67 (black rectangles), 31,32 which were weakened by the incorporation of Co, Ni, Mo or Pd, suggesting that the catalysts maintained the proper pore structure required for the HDS reaction. The peaks at 2q of 33 and 59 were ascribed to MoS 2 species in all catalysts 33,34 while Ni showed a weak peak at 2q of 60 in Ni-Mo/Al 2 O 3 and Pd-Ni-Mo/Al 2 O 3 .…”

Highly Advanced Degradation of Thiamethoxam by Synergistic Chemisorption-Catalysis Strategy Using MIL(Fe)/Fe-SPC Composites with Ultrasonic Irradiation

“…Zaltariov reported fast photodegradation rate of Congo red over Co/Cu-based MOFs as catalysts. Thus, these unsaturated open metal sites in MOFs can be motivated to generate electrons and holes that can take part in the redox reactions in their vicinity. , Moreover, catalytic activity can be further improved owing to their unique selective adsorption, marking them superior to some traditionally prepared metal-supported catalysts. , …”

“…Thus, these unsaturated open metal sites in MOFs can be motivated to generate electrons and holes that can take part in the redox reactions in their vicinity. 23,24 Moreover, catalytic activity can be further improved owing to their unique selective adsorption, marking them superior to some traditionally prepared metal-supported catalysts. 23,24 However, pure MOFs usually exhibit low quantum efficiency and poor electronic conductivity, 25 which can cause a fast recombination of the electron−hole (e − /h + ).…”

“…23,24 Moreover, catalytic activity can be further improved owing to their unique selective adsorption, marking them superior to some traditionally prepared metal-supported catalysts. 23,24 However, pure MOFs usually exhibit low quantum efficiency and poor electronic conductivity, 25 which can cause a fast recombination of the electron−hole (e − /h + ). To overcome this shortcoming, many researchers proposed the combination of MOFs with carbon substrates with good conductivity.…”
