Synthesis of Mesoporous McM-41 Materials With Low-Power Microwave Heating

Effect of loading bimetallic mixture of Ni and Pd on hydrogen storage capacity of MCM-41

“…5). These results confirm that the MCM-41 synthesized at 90 W had better thermal stability as a result of synthesis conditions when compared to previous results [10,17]. However, the structure is thermally stable even after PdeNi is loaded.…”

“…All the samples have a linear increase in their adsorption isotherms at low pressures (P/ i n t e r n a t i o n a l j o u r n a l o f h y d r o g e n e n e r g y 4 0 ( 2 0 1 5 ) 7 6 3 6 e7 6 4 3 P 0 < 0.25) due to the monolayer adsorption of N 2 on the pore walls. The drastic increase in the region of 0.25 < P/P 0 < 0.40 is attributed to the capillary condensation occurring inside the walls [10]. The long plateau at higher relative pressures suggests that the adsorption is continued on the surface of the samples following the capillary condensation [4].…”

“…Recently, a good alternative to hydrothermal processing which is microwave synthesis is used for MCM-41 production [9]. Microwave synthesis allows higher yields and better purity and increased rate of reaction and crystallization when compared to the conventionally used hydrothermal method [10]. Jiang et al, has successfully synthesized transition metals loaded MCM-41 by microwave irradiation [11].…”

Microwave-assisted post-synthesis modification of layered simple hydroxides

“…It has essentially been used in organic chemistry, 37 but also in coordination chemistry [38][39][40] and in materials chemistry. 41,42 It has also been used for the post-functionalization of nanoparticles 43 or of MOFs, 25,[44][45][46][47] but to the best of our knowledge it is the first time microwave heating is used for the internal post-synthesis modification of layered hybrid solids which are stable in a reduced range of pH.…”

Recent Progress of Microwave-Assisted Synthesis of Silica Materials

“…The effect of the applied microwave power to the synthesis of MCM-41 has also been studied [ 61 ]. Two powers were selected to carry out the reactions: 80 W and 120 W. Reaction temperatures of 90 °C and 120 °C were reached with 80 and 120 W respectively.…”
