Mesoporous silica nanoparticles (MSNs) are experiencing rapid development in the biomedical field for imaging and use heterogeneous catalysis. Although synthesis of MSNs with various morphologies particle sizes has been reported, a pore network monodispersion control below 200 nm is still challenging. We achieved this goal using mild conditions. The reaction occurred at atmospheric pressure templating sol-gel technique cetyltrimethylammonium (CTA(+)) as surfactant small organic amines (SOAs)...
A new route to the synthesis of TS-1 has been developed using (NH4)2CO3 as a crystallization-mediating agent. In this way, framework Ti content can be significantly increased without forming extraframework species. The prepared catalyst had Si/Ti ratio low 34 in contrast 58 achieved with methods and B established by Enichem group (Clerici, M. G.; Bellussi, Romano, U. J.

Using carboxylate-protected silver nanoclusters (Ag-carboxylate NCs) as a model, we separately investigated the contribution of ligand shell and metal core to understand nature photoluminescence Ag NCs. A new Ag(0)NCs@Ag(I)-carboxylate complex core-shell structural model has been proposed. The emission from Ag-carboxylate NCs could be attributed ligand-to-metal-metal charge transfer Ag(I)-carboxylate complexes (the oxygen atom in carboxylate ligands Ag(I) ions) atoms subsequent radiative...

One of the grand challenges in industrial catalytic processes is inevitable sintering and aggregation conventional supported catalysts to large particles, leading decrease activity even deactivation with time. Herein, a surface spatial confinement strategy was employed design high-performing for dry reforming methane (DRM). Specifically, active nickel (Ni) nanoparticles (NPs) were confined on dendritic mesoporous silica (DMS) form "catalysts coronas". The Ni/DMS catalyst exhibited high...
Zeolite-confined metal nanoparticles (NPs) have attracted much attention owing to their superior sintering resistance and broad applications for thermal environmental catalytic reactions. However, the pore size of conventional zeolites is usually below 2 nm, reactants are easily blocked access active sites. Herein, a facile in situ mesoporogen-free strategy developed design synthesize palladium (Pd) NPs enveloped single-crystalline zeolite (silicalite-1, S-1) with intra-mesopores (termed...
State-of-the-art technology for cyclohexanone oxime production typically demands elevated temperature and pressure, along with the utilization of expensive hydroxylamine sulfate or oxidants. Here, we propose an electrochemistry-assisted cascade strategy efficient ammoximation under ambient conditions by using in situ cathode-generated green oxidants reactive oxygen species (ROS) such as OOH* H 2 O . This electrochemical reaction can take place at cathode, achieving over 95% yield, 99%...
A novel titanosilicate with MWW topology, Ti-MWW, has been prepared by an acid treatment on a corresponding lamellar precursor which is hydrothermally synthesized the coexistence of boron and titanium using piperidine (PI) or hexamethyleneimine (HM) as structure-directing agent.
