We demonstrate, for the first time, that organic−inorganic hybrid hollow nanospheres with controllable size (12−20 nm) and shell thickness (4−7 can be successfully synthesized through condensation of 1,2-bis(trimethoxysilyl)ethane (BTME) around an inorganic-electrolyte-stabilized F127 micelle under a mild buffer condition (NaH2PO4−Na2HPO4, pH ∼7.0). The spheres feature microwindows pore about 0.5−1.2 nm on shell, which allow guest molecules to diffuse into cavities. It was found...
Cobalt-manganese spinel catalysts performed unsatisfactory activity at low-temperature and narrow reaction temperature window, which greatly limited the application in NO reduction by CO. Herein, we synthesize a series of Cu-doped CoMn2O4 apply to The Cu0.3Co0.7Mn2O4 exhibited superior catalytic performance, reaching 100% conversion 80% N2 selectivity 250 °C. Detailed structural analysis showed that introduced Cu replaces some Co tetrahedral coordination induce strong synergistic effect...
The example of syn-aldol reaction cyclohexanone to aldehyde was demonstrated based on chiral diamine organocatalysts and it realized either by increasing the molecular size acid additives or introducing a hydrogen-bond donor into additives.
The inner-surface functionalization of hollow silica spheres has rarely been reported and is still a challenging topic. Herein, we report deacetalization-Henry cascade reaction catalyzed by dual-functionalized mesoporous nanospheres with basic amine groups (NH2 ) on the internal shell carboxylic acid (COOH) external shell. selective realized combination "step-by-step post-grafting" "cationic surfactant-assisted etching" strategy. Compared to unisolated catalyst, selectively isolated acidic...

The nanocomposites formed by SO3H-hollow-nanospheres and chiral amines are highly efficient catalysts for the direct asymmetric aldol reaction of cyclohexanone 4-nitrobenzaldehyde. catalyst showed 91% yield with 96% ee under optimized conditions. were synthesized oxidation thiol-hollow-nanospheres, which fabricated through a one-pot co-condensation 1,2-bis(trimethoxysilyl)ethane 3-mercaptopropyltrimethoxysilane around F127 micelles in presence NaOAc. Chiral could be combined facile...
Ru-TsDPEN confined in the nanocage with an amphiphilic microenvironment can be ten times more active than that a hydrophobic one transfer hydrogenation of acetophenone HCOONa–H2O, which is mainly due to enhanced diffusion rates reactants during catalytic process.
A novel SnO2 nanoparticles/multi-walled carbon nanotubes/carbon paste electrode (nanoSnO2/MWCNTs/CPE) was prepared for simultaneous detection of dopamine (DA), uric acid (UA), and ascorbic (AA) via cyclic voltammetry (CV) differential pulse (DPV). The nanoSnO2/MWCNTs/CPE showed high electrochemical catalytic behavior DA, UA, AA. three compounds could be completely separated on the in CV DPV at optimal conditions. provided larger peak potential separations higher response sensitivities AA...

Large-pore mesoporous ethane-silicas functionalized with trans-(1R,2R)-diaminocyclohexane were synthesized in an acidic medium by one-step co-condensation of 1,2-bis(trimethoxysilyl)ethane and N-[(trimethoxysilyl)benzyl]-(−)-(1R,2R)-diaminocyclohexane using triblock copolymer P123 as template. The postmodification the pore was further demonstrated reaction p-toluenesulfonyl chloride. modified material (complexed [RhCp*Cl2]2) exhibits much higher conversion ee [53% 68% (R)] than original [18%...
Chirally functionalized hollow nanospheres with different surface properties were successfully synthesized by co-condensation of (2S,1'R,2'R)-N-tert-butyloxycarbonylpyrrolidine-2-carboxylic acid [2'-(4-trimethoxysilylbenzylamide)cyclohexyl] amide 1,2-bis(trimethoxysilyl)ethane or tetramethoxysilane using F127 (EO(106)PO(70)EO(106)) as surfactant in water. The TEM and N(2) sorption characterizations show that the particle size nanosphere is 15-21 nm a core diameter 10-16 nm. These...
The dynamic adsorption/desorption behavior of VOCs (C7H8) was evaluated for mesoporous SBA-15 silicas with four kinds morphologies and pore sizes on a fixed bed unit. silica interconnected rodlike morphology exhibited exceptionally good breakthrough behavior, higher adsorption capacity, better desorption performance toluene. large VOC capacity the attributed to system micropores mesopore size, group-togethering rods which can aggregate enhance ability adsorption, together smoother surface.
