Abstract: Encapsulation of Pt nanoparticles (NPs) in zeolitic imidazolate frameworks (ZIFs) was achieved via assembly of ZIF nanostructures around the pre-formed "unprotected" NPs. Ptn@ZIF-8 showed efficient size-selective hydrogenation ability due to the uniform microporous structure.

Abstract: Learning from nature, one of the most prominent goals of photocatalysis is to assemble multifunctional photocatalytic units in an integrated, high performance device that is capable of using solar energy to produce “solar hydrogen” from aqueous media. By analogy with natural systems it is clear that scaffolds with multi-scale structural architectures are necessary. In this perspective, recent progress related to the use of hollow micro/nanomaterials as nanoreactors for photocatalysis is discussed. Organised, multi-scale assemblies of photocatalytic units on hollow scaffolds is an emerging area that shows much promise for the synthesis of high performance photocatalysts. Not only do improved transport and diffusion characteristics play an import role, but increased electron/hole separation lifetimes as well as improved light harvesting characteristics by the hollow structures also do so and are touched upon in this short perspective.

Abstract: In this communication we have demonstrated the synthesis of organosilica nanotubes with inner diameter of ∼6 nm and their carbonization to form carbon/silica composite nanotubes. Pd nanoparticles. encapsulated in the organosilica and carbon/silica nanotubes show different catalytic activities in the hydrogenation of cyclohexene.

Abstract: A solvothermal post-treatment method was developed to synthesize Fe(3)O(4)@mesosilica core-shell nanospheres (CSNs) with a well-preserved morphology, mesoporous structure, and tunable large pore diameters (2.5-17.6 nm) for the first time. N,N-Dimethylhexadecylamine (DMHA), which was generated in situ during the heat-treatment process, was mainly responsible for this pore-size enlargement, as characterized by NMR spectroscopy. This pore-size expansion can be strengthened with the aid of hexamethyldisilazane (HMDS), whilst the nature of the surface of the Fe(3)O(4)@mesosilica CSNs can be easily modified with trimethylsilyl groups during the pore-size-expansion process. The hydrophobicity of the Fe(3)O(4)@mesosilica CSNs increased for the enlarged mesopores and the adsorption capacity of these CSNs for benzene (up to 1.5 g g(-1)) is the highest ever reported for Fe(3)O(4)@mesosilica CSNs. The resultant Fe(3)O(4)@mesosilica CSNs (pore size: 10 nm) showed a 3.6-times higher adsorption capacity of lysozyme than those without the pore expansion (pore size: 2.5 nm), thus making them a good candidate for loading large molecules.

Abstract: We introduce the visible-light photocatalytic H2 evolution reaction as catalyzed by a cobaloxime/carbon nitride (C3N4) noble-metal-free hybrid photosystem by using a continuous-flow s ling reaction system. The photocatalytic H2 evolution rate is highly dependent on the structure of C3N4, in which porous C3N4 shows the best activity compared with bulk C3N4 (lamellar) and C3N4 nanosheets. When using porous C3N4, the system is neither affected by the solution pH, nor the C3N4 concentration, nor the structure of the cobaloxime complex.

Abstract: Smart yolk-shell nanoparticles (hollow nanoparticles with a movable core) with an acidic shell and a basic core were fabricated through an organosilane-assisted selective etching method and acted as efficient nanoreactors for catalyzing a deacetalization-Henry cascade reaction with high activity and high selectivity. This strategy is very promising for the design of multifunctional nanoreactors for cascade reactions.

Abstract: Metal-free polymeric carbon nitrides (PCNs) are promising photocatalysts for solar hydrogen production, but their structure-photoactivity relationship remains elusive. Two PCNs were characterized by dynamic-nuclear-polarization-enhanced solid-state NMR spectroscopy, which circumvented the need for specific labeling with either

Abstract: A library of 237 organic binary/ternary nanohybrids consisting of conjugated polymers donors and both fullerene and non-fullerene molecular acceptors was prepared and screened for sacrificial photocatalytic hydrogen evolution. These donor-acceptor nanohybrids (DANHs) showed significantly enhanced hydrogen evolution rates compared with the parent donor or acceptor compounds. DANHs of a polycarbazole-based donor combined with a methanofullerene acceptor (PCDTBT/PC 60 BM) showed a high hydrogen evolution rate of 105.2 mmol g -1 h -1 under visible light (λ 420 nm). This DANH photocatalyst produced 5.9 times more hydrogen than a sulfone-containing polymer (P10) under the same conditions, which is one of the most efficient organic photocatalysts reported so far. An apparent quantum yield of hydrogen evolution of 3.0 % at 595 nm was measured for this DANH. The photocatalytic activity of the DANHs, which in optimized cases reached 179.0 mmol g -1 h -1 , is attributed to efficient charge transfer at the polymer donor/molecular acceptor interface. We also show that ternary donor A -donor B -acceptor nanohybrids can give higher activities than binary donor-acceptor hybrids in some cases.

Abstract: Secondary building blocks within the cavities of primary silica-architecture building blocks are successfully engineered. The immobilized surfactant directs the selective dissolution and reassembly of dissolved silicate species for the formation of secondary building blocks (hollow nanospheres/nanorods see figure). Supported TiO(2) on nanostructures with multilevel interiors is shown to exhibit significantly enhanced activity in photocatalytic H(2) production.
