Effect of Method on Monolayer Assembly of Zeolite Microcrystals on Glass with Molecular Linkages

Abstract

The effect of method on the mode of reaction progress and the characteristic properties of the assembled monolayers were investigated during the monolayer assembly of bare zeolite microcrystals onto 3-chloropropyl-tethering glass plates. The tested methods were reflux, reflux with stirring, sonication, and sonication with stacking between the glass plates. The results revealed that the type of method sensitively affects the profiles of the coverage and the binding strength with time and that the monolayer assembly consists of four key steps: dispersion of microcrystals into the solution, attachment of microcrystals onto the substrate, migration of the randomly attached crystals leading to close packing between the microcrystals, and replacement of the substrate-bound microcrystals with those in solution.

Artificial Photosynthesis

“…1-D channel materials, such as zeolites and mesoporous silicas, are very attractive hosts for the preparation and investigation of hierarchically organized structures, presenting a successive ordering from the molecular up to macroscopic scale; thus highlighting the relationship between molecular arrangements and macroscopic properties [3][4][5][6][7][8]. The maintenance of life on earth, food, oxygen, and fossil fuels depend on the conversion of solar energy into chemical energy by biological photosynthesis carried out by green plants.…”

Effect of Mode of Binding Linkage on Monolayer Assembly of Zeolite

“…In the previously study, 20,21 we have investigated the effects of MRP on the progress of the monolayer assembly of zeolite microcrystals on glass through large numbers of molecular covalent linkages between zeolite microcrystals and glass plates and the characteristic properties of the assembled monolayers. Again, by charged amount (A C ) of zeolite microcrystals into account, we have discussed how DOC and BS are governed with the MRP undergoing of the cycle of bond-formation and bond-breakage during the courses of surface migration and replacement of the attached crystals with those in the solution.…”

“…In the previously study, [20][21][22] we have shown that the attachment of the zeolite microcrystals starts from the bottom and then propagate to the top with time through repeatedly undergoing the cycle of bond-formation and bond-breakage. Therefore, we demonstrated that the initially intruded microcrystals are pushed up by the subsequently intruding crystals, leading to higher DCPs from the beginning.…”

“…20,21 This method was named as 'sonication with stacking' (SS). Furthermore, under the SS mode, we found an interesting phenomenon that BS, DOC, and DCP gradually decrease with increasing the reaction time, despite of DOC reaches ~100% with a quite fast r A .…”
