The development of a highly efficient and stable bifunctional electrocatalyst for water splitting is still a challenging issue in obtaining clean and sustainable chemical fuels. Herein, a novel bifunctional catalyst consisting of 2D transition-metal phosphide nanosheets with abundant reactive sites templated by Co-centered metal-organic framework nanosheets, denoted as CoP-NS/C, has been develo...

Silica mesoporous nanocomposite films containing graphene nanosheets and gold nanoparticles have been prepared via a one-pot synthesis using silicon tetrachloride, gold(III) chloride tetrahydrate, a 1-N-vinyl-2-pyrrolidone dispersion of exfoliated graphene and Pluronic F127 as a structuring agent. The composite films have shown graphene-mediated surface-enhanced Raman scattering (G-SERS). Graph...

Vapor-phase growth of large-area two-dimensional (2D) MoS2 nanosheets via reactions of sulfur with MoO3 precursors vaporized and transferred from powder sources onto a target substrate has been rapidly progressing. Recent studies revealed that the growth yield of high quality singlelayer (SL) MoS2 is essentially controlled by quite a few parameters including the temperature, the pressure, the a...

Molecularly Thin Perovskite Ferroelectric Two-dimensional (2D) Ti0.87O2 nanosheets can serve as templates, guiding the low temperature synthesis of 2D BaTiO3 with a molecularly thin thickness (<3 nm). The 1.8-nm thick nanosheet is thinnest free-standing perovskite to experimentally confirm ferroelectricity so far. More details be found in article number 2201239 by Minoru Osada and co-workers.

Wet-chemical syntheses of quasi two-dimensional (2D) transition metal dichalcogenides (TMDs) have emerged as promising methods for straightforward solution-processing these materials. However, the photoluminescence (PL) properties colloidal TMDs are virtually unexplored due to typically nonemitting synthesis products. In this work, we demonstrate room temperature micro-PL delicate ultrathin WS2...
