Ordered Porous Pd Octahedra Covered with Monolayer Ru Atoms
Monolayer Ru atoms covered highly ordered porous Pd octahedra have been synthesized via the underpotential deposition and thermodynamic control. Shape evolution from concave nanocube to octahedron with six hollow cavities ...
Three-dimensional graphene foam supported Fe3O4 lithium battery anodes with long cycle life and high rate capability
Fe3O4 has long been regarded as a promising anode material for lithium ion battery due to its high theoretical capacity, earth abundance, low cost and nontoxic properties. However, up to now, no effective and scalable ...
Oriented molecular attachments through sol–gel chemistry for synthesis of ultrathin hydrated vanadium pentoxide nanosheets and their applications
Ultrathin single-crystalline V2O5·0.76H2O nanosheets with a thickness of 1.5–2.6 nm are prepared on the basis of molecular-level ‘oriented attachment’ through special sol–gel chemistry. The initial formation of 3–7 nm ...
Synthesis of few-layer MoS2 nanosheet-coated TiO2 nanobelt heterostructures for enhanced photocatalytic activities
MoS2 nanosheet-coated TiO2 nanobelt heterostructures—referred to as TiO2@MoS2—with a 3D hierarchical configuration are prepared via a hydrothermal reaction. The TiO2 nanobelts used as a synthetic template inhibit the growth ...
Graphene-Based Materials for Solar Cell Applications
Graphene has attracted increasing attention due to its unique electrical, optical, optoelectronic, and mechanical properties, which have opened up huge numbers of opportunities for applications. An overview of the recent ...
