Journal ArticleDOI
Dynamic Pt-OH-·H2O-Ag species mediate coupled electron and proton transfer for catalytic hydride reduction of 4-nitrophenol at the confined nanoscale interface.
TL;DR: In this article , with Pt-Ag bimetallic nanoparticles confined in dendritic mesoporous silica nanospheres (DMSNs) as a model catalyst, the authors demonstrated that the conversion of 4-NP did not pass through the direct hydrogen transfer route with the hydride equivalents being supplied by borohydride via the bimolecular L-H mechanism, since Fourier transform infrared (FTIR) spectroscopy with the use of isotopically labeled reactants (NaBD4 and D2O) showed that the final product was composed of protons (or deuterons) that originated from the solvent water (or heavy water).

Physical Origin of Dual-Emission of Au-Ag Bimetallic Nanoclusters.
Bo Peng,Liu-Xi Zheng,Pan-Yue Wang,Jia-Feng Zhou,Meng Ding,Hao-Di Sun,Bing-Qian Shan,Kun Zhang +7 more
TL;DR: In this article, structural water molecules (SWs) confined in the nanocavity formed by surface-protective-ligand packing on the metal NCs are the real luminescent emitters of Au-Ag bimetal NCs.
Journal ArticleDOI
From ill-resolved atomic to ZSM-5 type of ordering in mesoporous lamellar aluminosilica nanoparticles
TL;DR: In this paper, a mesophase of the MFI type of zeolite has been used to synthesize mesophases of aluminosilicate-surfactant nanoparticles.
Journal ArticleDOI
Tailoring porosity and dimensionality of Co3O4 nanophase using channel interconnectivity control by steaming of nanocasting SBA-15
Ma Xiaojing,Yu Yejun,Xing Junling,Tai-Qun Yang,Koon Fung Lam,Qing-Song Xue,Belén Albela,Laurent Bonneviot,Kun Zhang +8 more
TL;DR: In this paper, a clean, efficient and facile high temperature steam post-treatment is proposed to control the microporosity and the interconnectivity of the nanocasted oxide phase.

Preparation method of mesoporous silica spherical nano particles with dendritic pore structure
TL;DR: In this paper, a method of mesoporous silica spherical nano particles with a dendritic pore structure was presented, where a template agent adopted by the method is cetyltrimethyl p-methylbenzene ammonium sulfonate, an alkali source is organic small-molecular amine, and a silicon source is tetra-alkyl silicate ester.
