Abstract
Selective hydrogenation of cinnamaldehyde (CAL) to cinnamyl alcohol (COL) is difficult due to the intrinsic difficulty with thermodynamically easier hydrogenation of C═C bonds. In this work, Pt-CoxOy hybrid nanoparticles encapsulated in mesoporous silica nanospheres (Pt-CoxOy@mSiO2) were synthesized by a sol-gel method, which showed greatly improved COL selectivity for hydrogenation of CAL. At 80 °C and 1.0 MPa of H2, Pt-CoxOy@mSiO2 achieved a CAL conversion of 98.7% with a COL selectivity of 93.5%. In contrast, Pt@mSiO2 yields 3-phenylpropanol (HCOL) as the major product with HCOL selectivity of 67.2%, while PtCo@mSiO2 yields 3-phenylpropionaldehyde with selectivity of 51.8% under the same conditions. The enhanced catalytic performance of Pt-CoxOy@mSiO2 for hydrogenation of CAL to COL is ascribed to the Pt surface electron deficiency induced by metal-oxide interaction, and the protection of active NPs by silica shells results in good catalytic stability.

Abstract
Pd-CoxOy heteroaggregate-encapsulated hollow porous silica nanoreactors (Pd-CoxOy@HPSNs) were synthesized by a reverse microemulsion system. The key design of the developed reverse microemulsion system is to use poly(ethyleneimine) in the water droplets as the void templates for silica deposition and for anchoring the catalytic functionality inside the hollow silica nanospheres. The synthesized Pd-CoxOy@HPSNs contain ∼3 nm Pd-CoxOy hybrid nanostructures in ∼10 nm central cavities of silica nanospheres and illustrated a significantly promoted efficiency for hydrodechlorination of a series of chlorophenols into phenols under mild reaction conditions. The catalytic enhancement of Pd-CoxOy@HPSNs is ascribed to the synergistic effect between Pd and CoxOy and the protection of silica shells to the inner catalytic functionality.

Abstract
Cadmium ions have been of crucial concern due to the high biological toxicity and serious environmental risks. Various fluorescent Cd-sensitive probes have been reported with improved sensing properties, but still severely suffer from poor stability and insufficient selectivity. In this work, a stable fluorescent probe based on silica encapsulated quantum dots (QDs) have been developed for rapid, sensitive and selective detection of cadmium ion. To improve fluorescence stability, the strategy of mesoporous silica encapsulation was adopted, in which the mesoporous silica shell offers numerous channels for Cd2+. Further, the Forster Resonance Energy Transfer (FRET) system, where QDs@mSiO2and rhodamine B (RB) are used as donors and acceptors respectively, has been constructed, in which the mesoporous silica shell also serves as spacers with tunable thickness for controlling the QD-RB distance. Under optimal conditions, the probes possess a sensitive fluorescence response with a detection limit of 1.25μM. Visual detection can be realized by the obvious fluorescence changes of the FRET system. In addition, the FRET system shows promising sensing performances both in tap water samples and rice-washed water samples, confirming a great potential for practical application.

Abstract
Hollow and mesoporous aluminosilica nanoreactors (HMANs) with Pt-CoOx cores (∼4.7 nm) and hollow aluminosilica shells (∼50 nm) were designed by a selective etching method. The Pt-CoOx@HMANs demonstrate a greatly enhanced activity and selectivity for the hydrogenation of various substituted nitroaromatics compared to Pt@HMANs and Pt-CoOx@SiO2.

Abstract
Nanosized Au catalysts suffer from serious sintering problems during synthesis or catalytic reactions at high temperatures. In this work, we integrate dumbbell-shaped Au-Fe3O4 heterostructures into hollow ZrO2 nanocages to make Au-Fe2O3@ZrO2 yolk-shell nanoreactors with high activity as well as ultra-high sintering resistance for high-temperature CO oxidation. The synthesis starts with the fabrication of a (Au-Fe3O4)@SiO2@ZrO2 core-shell nanostructure with a Au-Fe3O4 dumbbell nanoparticle (DB) core and SiO2/ZrO2 double shells, followed by calcination and the selective removal of the inner SiO2 shell with alkaline solution to obtain Au-Fe2O3@ZrO2 nanoreactors. The retained ZrO2 hollow (outer) shells protect the Au NPs from aggregation at temperatures up to 900 °C and show excellent long-term stability. Compared to Au@ZrO2 yolk-shell nanoreactors, Au-Fe2O3@ZrO2 shows improved activity in CO oxidation due to the active Au-Fe2O3 interface. This strategy can be extended to other yolk-shell nanoreactors with various nanocomposites and for different catalytic reactions.

Abstract
Decoration of noble metals with transition-metal oxides has been intensively studied for heterogeneous catalysis. However, controllable syntheses of metal-metal oxide heterostructures are difficult, and elucidation of such interfaces is still challenging. In this work, supported IrCo alloy nanoparticles are transformed into supported Ir-CoOx close-contact nanostructures by in situ calcination and following selective reduction. Relative to Ir/Al2O3, Ir-CoOx/Al2O3 shows greatly enhanced activities for the hydrogenation of furfural derivatives to the corresponding furfuryl alcohol derivatives with more than 99% selectivity and demonstrates significantly improved activities and selectivity for hydrogenations of α,β-unsaturated aldehydes to α,β-unsaturated alcohols. The modification of Ir surfaces with CoOx prevents Ir nanoparticles from growing, achieving high thermal and catalytic stabilities. Theoretic calculation suggests that the better catalytic performance of Ir-CoOx/Al2O3 is ascribed to the Ir-CoOx interaction, which promotes the absorption of furfural as well as desorption of furfuryl alcohol, resulting in enhanced catalytic activities.
