“…Incorporation of metal species blocked the pores of the supported silica MCM-41 and reduced the specific surface area and pore volume. [56,57] The hysteresis curve indicates that the metal species distributed all over the channels of MCM-41. The metal species were not agglomerated at the opening of mesopores of MCM-41.…”

MCM-41-supported ZnOÀ Cu(OH)Cl nanoparticles were synthesized via an incipient wetness impregnation technique using zinc chloride and copper chloride salts as well as water at room temperature. The catalyst was characterized by powder X-ray diffraction (PXRD), infrared spectroscopy (IR), and TGA, whereas surface and morphological studies were performed by using scanning electron microscopy (SEM) and transmission electron microscopy (TEM). The above studies revealed the incorporation of metal species into the pores of MCM-41, leading to a decrease in surface area of the nanoparticles that was found to be 239.079 m 2 /g. The substituents attached to the ketone determine the rate of the reaction, and the utilization of the green solvent 'water' astonishingly completes the hydrogenation reaction in 45 minutes at 40°C with 100% conversion and 100% selectivity as analyzed by gas chromatography-mass spectrometry. Hence, ZnOÀ Cu(OH)Cl/MCM-41 nanoparticles with 2.46 wt% zinc and 6.39 wt% copper were demonstrated as an active catalyst for the reduction of ketones without using any gaseous hydrogen source making it highly efficient as well as environmentally and economically benign.

“…40 Therefore, MCM-41 materials applied in many elds as catalysts or catalyst supports. 41,42 The integration of MOFs on mesoporous materials as MCM-41 would produce multiple interfaces, which created synergistic effects from multiple components by integration of more than two active sites such as bimetallic or multimetallic catalysts which improve the catalytic activity. 43 Amidoalkyl naphthol derivatives are one of the multicomponent reactions (MCRs) which have a great importance nowadays because of their essential role in organic synthesis as formation of desired products in a single synthetic process without any separation problems which in role show high atom economy and high selectivity.…”

“…It is well known that insert carbon requires much oxidization temperature. The result indicated the insert carbon easily occurred at high-loading sample and supported catalyst [42]. Based on the characterization results reported elsewhere [43,44], the graphic-like carbon should be deposited onto 15%Ni-MCM-41 and 10%Ni/MCM-41, however, no diffraction peak was observed in XRD due to trace amount of coking.…”

The supporting modes of active metal over mesoporous materials play an important role in catalytic performance. The location of Ni nanoparticles inside or outside the mesoporous channel of MCM-41 has a significant influence on the reactivity in partial oxidation of methane to syngas reaction. The characterization data using different techniques (Transmission Electron Microscope (TEM), X-Ray Diffraction (XRD), N2 adsorption-desorption, H2 Temperature-Programmed Reduction (H2-TPR), and Inductively Coupled Plasma (ICP)) indicated that nickel was located outside the mesoporous channels for the impregnation method (Ni/MCM-41), while nickel was encapsulated within MCM-41 via the one-step hydrothermal crystallization method (Ni-MCM-41). The nickel atoms were mainly dispersed predominantly inside the skeleton of zeolite. When the load amount of Ni increased, both of Ni species inside the skeleton or pore channel of zeolite increased, and the ordered structure of MCM-41 was destroyed gradually. Contributed by the strong interaction with MCM-41, the Ni particles of Ni-MCM-41 were highly dispersed with smaller particle size compared with supported Ni/MCM-41 catalyst. The Ni-MCM-41 displayed higher catalytic performance than Ni/MCM-41, especially 10% Ni-MCM-41 due to high dispersity of Ni. The confinement effect of MCM-41 zeolite also afforded high resistance of sintering and coking for 10% Ni-MCM-41 catalyst. Especially, 10% Ni-MCM-41 catalyst showed outstanding catalytic stability.
