Control over porosity and exposed highly reactive facets is challenging in the area of materials science. Materials with high porosity and reactivity of exposed facets are favorable candidates in catalysis and energy storage. Here we demonstrate a facile template-free route to synthesize nanoporous LiMn2O4 nanosheets composed of single-crystalline LiMn2O4 nanorods with exposed {111} facets via ...
For conventional dye or quantum dot sensitized solar cells, which are fabricated using mesoporous films, the inefficient electron transport due to defects such as grain boundaries and surface traps is a major drawback. To simultaneously increase the carrier transport efficiency as well as the surface area, optimal-assembling of hierarchical nanostructures is an attractive approach. Here, a thre...
In this work, we designed a sensitivity-enhanced surface plasmon resonance biosensor structure based on silicon nanosheet and two-dimensional transition metal dichalcogenides. This configuration contains six components: SF10 triangular prism, gold thin film, silicon nanosheet, two-dimensional MoS2/MoSe2/WS2/WSe2 (defined as MX2) layers, biomolecular analyte layer and sensing medium. The minimum...
Fe/ZSM-5 nanosheet zeolites of varying thickness were synthesized with di- and tetraquaternary ammonium structure directing agents and extensively characterized for their textural, structural, and catalytic properties. Introduction of Fe3+ ions in the framework of nanosheet zeolites was slightly less effective than in bulk ZSM-5 zeolite. Steaming was necessary to activate all catalysts for N2O ...
With an average diameter of ≈2 nm, on-surface synthesized amino-ferrocene nanoclusters are chemisorbed onto a graphene oxide nanosheet, where their Fe ions in S = 5/2 high-spin state. In this two-dimensional (2D) nanomaterial, the molecular spins given nanocluster weakly magnetic dipole interacting. It generates spin correlations and slow dynamics accessible by susceptibility Mössbauer spectros...
