Visible light driven 3D hierarchical CoTiO3/BiOBr direct Z-scheme heterostructure with enhanced photocatalytic degradation performance

A series of novel three-dimensional (3D) CoTiO3/BiOBr (CTBB) hierarchical heterostructures were prepared via a simple hydrothermal method. In comparison with pure CoTiO3 and BiOBr, all the CTBB nanocomposites display enhanced...

Electrostatic repulsion strategy for highly selective and sensitive “switch–on” fluorescence sensor of ascorbic acid based on the cysteamine-coated CdTe quantum dots and cerium (IV)

In this work, cysteamine-coated CdTe quantum dots (CA-CdTe QDs) were synthesized by a simple hydrothermal method employing cadmium chloride as the cadmium source and cysteamine hydrochloride as the functional monomer....

Dual Mode Emissions with Enhanced Green Up-conversion Luminescence by Gd3+ Doping and Down-conversion from Eu3+ in NaMnF3:Yb,Er@NaGdF4:Eu

NaMnF3:Yb,Er and NaMnF3:Yb,Er@NaGdF4:xEu (x = 0, 0.3, 0.6, 0.9) samples were synthesized by a simple hydrothermal method. The as-obtained NaMnF3:Yb,Er particles show single red emitting under the irradiation of infrared...

New rationally designed hybrid polypyrrole@SnCoS4 as an efficient anode for lithium-ion batteries

Three active materials containing binary metal sulfide (SnCoS4) were obtained via a simple hydrothermal method. Also, the electrochemical performance of the anode materials was investigated in a lithium-ion half-cell.

Synthesis of palygorskite supported spherical ZnS nanocomposites with enhanced photocatalytic activity

In this paper, palygorskite (Pal) and spherical zinc sulfide (ZnS) nanopowder were successfully synthesized by using a simple hydrothermal method. The ZnS nanoparticles were supported on the framework of Pal...

Double activating peroxymonosulfate with g-C3N4/Fe2(MoO4)3 to enhanced photocatalytic activity under visible light irradiation

Fe2(MoO4)3 photocatalysts were synthesized by a simple hydrothermal method. Fe2(MoO4)3 photocatalysts showed lower photocatalytic activity for the degradation of methylene blue under visible light irradiation. After composited with g-C3N4, the...

Hollow ZnO nanorices prepared by a simple hydrothermal method for NO2 and SO2 gas sensors

Hollow ZnO nanorices with an ultrathin shell show excellent response to NO2 and SO2 gases.

Metal–organic framework-derived Ni-based catalyst for the hydrotreatment of triolein into green diesel

In this work, novel Ni-based catalysts supported on a porous carbon matrix were prepared using a simple hydrothermal method, and studied for the selective hydrotreatment of triolein.
