Developing noble metal-free water oxidation catalysts is essential for many energy conversion/storage processes (e.g., splitting). Herein, we report the facile synthesis of hollow Co3O4 microspheres composed porous, ultrathin (<5 nm), single-crystal-like nanosheets via a novel "self-template" route. The successful preparation these nanomaterials includes three main steps: (1) solid cobalt alkoxide microspheres, (2) their subsequent self-template conversion into hydroxide nanosheets, and...
Abstract Efficient charge separation and utilization are critical factors in photocatalysis. Herein, it is demonstrated that the complete spatial of oxidation reduction cocatalysts enhances efficacy surface reaction. Specifically, a Pt@NH 2 ‐UiO‐66@MnO x (PUM) heterostructured photocatalyst with Pt MnO as designed for optimization NH ‐UiO‐66 photocatalyst. Compared pristine ‐UiO‐66, (PU), (UM) samples, PUM sample exhibits highest hydrogen production activity. As cocatalysts, favors trapping...

Its structure is composed of Zn4O(CO2)7 secondary building units linked by mixed ligands, exhibiting a three-dimensional framework. Fluorescence...
Nitrogen-doped (N-doped) photoluminescent carbon dots (CDs) were prepared by a one-pot microwave-assisted hydrothermal treatment using histidine as the sole source in absence of acid, alkali, or metal ions. With diameter 2–5 nm, synthesized CDs had apparent lattice fringes and exhibited an excitation-dependent behavior. The highly yielded, well-dispersed aqueous solution, showed high photostability solutions wide range pH salinity. They used probes to identify presence Fe3+ ions with...
Monodisperse water-soluble hexagonal phase Ln(3+)-doped NaGdF(4) upconverting nanocrystals (UCNCs) have been successfully fabricated by means of a fast, facile, and environmentally friendly microwave-assisted route with polyethylenimine as the surfactant. Fine-tuning UC emission from visible to near-IR finally white light has achieved. Furthermore, studies magnetic resonance imaging well magnetization (magnetization-magnetic field curves) targeted recognition properties FA-coupled...
Exposure to brominated flame retardants (BFRs) has been widely confirmed impair the normal functioning of human body system. However, there is a paucity study on effects serum BFRs bone mineral density (BMD). This aims investigate relationship between exposure and BMD in nationally representative sample U.S. adults.

Lanthanide-doped core–shell upconversion nanocrystals (UCNCs) have tremendous potential for applications in many fields, especially bio-imaging and medical therapy. As UCNCs are mostly synthesized organic solvents, tedious organic–aqueous phase transfer processes usually needed their use bio-applications. Herein, we demonstrate the first example of one-step synthesis highly luminescent "aqueous" under mild conditions using innocuous reagents. A microwave-assisted approach allowed...
