Palladium nanoparticles immobilized on core–shell magnetic fibers as a highly efficient and recyclable heterogeneous catalyst for the reduction of 4-nitrophenol and Suzuki coupling reactions
A novel core–shell magnetic fibrous nanocatalyst, Pd/Fe 3 O 4 @SiO 2 @KCC-1 with easily accessible active sites and a convenient recovery property, was successfully developed.
A new approach for rapid electrolyte wetting in tape cast electrodes for lithium-ion batteries
A dramatic acceleration of electrode wetting with liquid electrolyte was achieved by laser-assisted formation of capillary microstructures in cathode materials.
Mesoscopic TiO2/CH3NH3PbI3 perovskite solar cells with new hole-transporting materials containing butadiene derivatives
Two new triphenylamine-based hole-transporting materials (HTMs) containing butadiene derivatives are employed in CH3NH3PbI3 perovskite solar cells. Up to 11.63% of power conversion efficiency (PCE) has been achieved. Advantages such as easy synthesis, low cost and relatively good cell performance exhibit a possibility…
Porous Pd nanoparticles with high photothermal conversion efficiency for efficient ablation of cancer cells
Nanoparticle (NP) mediated photothermal effect shows great potential as a noninvasive method for cancer therapy treatment, but the development of photothermal agents with high photothermal conversion efficiency, small size and good biocompatibility is still a big challenge. Herein, we report Pd NPs with a porous struc…
Development of a Ru complex-incorporated MOF photocatalyst for hydrogen production under visible-light irradiation
A Ru complex-incorporated Ti-based MOF (Ti-MOF-Ru(tpy)2) has been synthesised by using a bis(4'-(4-carboxyphenyl)-terpyridine)Ru(ii) complex (Ru(tpy)2) as an organic linker. Ti-MOF-Ru(tpy)2 promotes photocatalytic hydrogen production from water containing a sacrificial electron donor under visible-light irradiation up…
Enlarging the d-spacing of graphite and polarizing its surface charge for driving lithium ions fast
Lithium ion movement was accelerated by enlarging the interlayer distance of graphite as well as by polarizing its surface charge. As a result, the rate performances of lithium ion batteries were significantly enhanced.
Graphene–BODIPY as a photocatalyst in the photocatalytic–biocatalytic coupled system for solar fuel production from CO2
The utilization of CO2 for production of solar fuels/chemicals is gaining increasing importance due to worldwide fossil-fuel shortage and global warming. As a means to achieve this, we herein report on the synthesis and development of a graphene-based visible light active photocatalyst (CCG–BODIPY) which is chemically…
Ultrahigh porosity in mesoporous MOFs: promises and limitations
Mesoporous MOFs are currently record holders in terms of the specific surface area with values exceeding 7000 m(2) g(-1), a textural feature unattained by traditional porous solids such as zeolites, carbons and even by graphene. They are promising candidates for high pressure gas storage and also for conversion or sep…
Aluminum–air battery based on an ionic liquid electrolyte
This study presents a novel non-aqueous Al–air battery utilizing 1-ethyl-3-methylimidazolium oligo-fluoro-hydrogenate room temperature ionic liquid. The Al–air-RTIL system can sustain current densities up to 1.5 mA cm −2 , producing capacities above 140 mA h cm −2 , thus utilizing above 70% of the theoretical Al capac…
In situ surface hydrogenation synthesis of Ti 3+ self-doped TiO 2 with enhanced visible light photoactivity
A novel one-step, vapor-fed aerosol flame synthetic process (VAFS) has been developed to prepare Ti(3+) self-doped titanium dioxide (TiO2). The freshly formed TiO2 was in situ surface hydrogenated during the condensation stage by introducing H2 above the flame, and Ti(3+) ions were created near the surface of TiO2. Th…
Straightforward access to mono- and bis-cycloplatinated helicenes displaying circularly polarized phosphorescence by using crystallization resolution methods
Enantiopure mono-cycloplatinated-[8]helicene and bis-cycloplatinated-[6]helicene derivatives were prepared through column chromatography combined with crystallization of diastereomeric complexes using a chiral ancillary sulfoxide ligand.
