Surfactant free synthesis of gold nanoparticles within meso-channels of non-functionalized SBA-15 for its promising catalytic activity

Encapsulation methods of active molecules for drug delivery

“…All the above methods often involve the use of toxic solvents and / or surfactants that are dangerous to the environment as well as to physiological systems [48]. Consequently, current research has been directed to explore safer techniques to develop carriers of ….…”

A comprehensive study on removal of cadmium from aqueous solution by using mesoporous SBA-15 functionalized by 1,5-diphenyl carbazide: experimental design, kinetic, thermodynamic, and isotherm aspects

“…Additionally, 55.0 mL of toluene, 1.2 mL of trimethylamine, and 0.50 g of DPC were then added to 1.0 g Cl-SBA-15. Finally, the mixture was refluxed for 24 h at 115°C under N 2 atmosphere, and the functionalized adsorbent (DPC-SBA-15) was separated and rinsed by toluene and then dried in vacuum at 80°C [36].…”

Gold nanoparticles stabilized by modified halloysite nanotubes for catalytic applications

“…The applicability of the reaction was investigated using a set of nitroarene derivatives ( Figure S4) having either electron-donating or electron-withdrawing groups in different positions with respect to the nitro group (Table 6). To achieve this scope, we chose to run the reactions in the presence of 0.1 mol% of catalyst with 50 mM NaBH 4 to clearly monitor the conversion efficiency of the [30] PMMA 6.9 7.2 × 10 -3 88.6 [31] CNs 10-30 2.1 × 10 −3 109 [27] Chitosan 3.1 1.2 × 10 −2 50.4 [32] AOBC 10.6 4.5 × 10 −3 1198 [26] CSNFs 5 5.9 × 10 −3 563 [33] NCC-G AT 0 3.5 2.8 × 10 −3 608 [34] SBA-15 2.3 1.7 × 10 −2 -a [35] NC 5.7 3.6 × 10 −3 1185 b [24] Glucan 8 1.9 × 10 −3 5922 [36] MgAlCe-LDH 3 4.1× 10 −2 1 200 000 [29] HNTs reaction. It seems clear that the presence of a strong electron-donating substituent at the para position with respect to the reacting nitro group is an important requirement for the reaction to occur (entries 1, 4, 5, 6).…”
