Ag/AgX/BiOX (X = Cl, Br) three-component visible-light-driven (VLD) photocatalysts were synthesized by a low-temperature chemical bath method and characterized X-ray diffraction patterns, photoelectron spectroscopy, field emission scanning electron microscopy, transmission high-resolution UV–vis diffuse reflectance spectra. The composites showed enhanced VLD photocatalytic activity for the degradation of rhodamine B, which was much higher than Ag/AgX BiOX. mechanisms analyzed active species...
BiOCl nanosheets (BiOCl NSs) were synthesized by hydrolyzing a hierarchical flowerlike molecular precursor (Bin(Tu)xCl3n, Tu = thiourea). High photoactivity of {001} facets NSs was observed, and the mechanism discussed.
Photocatalysis technology, using semiconductor nano-materials to decompose toxic pollutants under solar light irradiation, displays great prospects for environmental protection. This review gives an overview of the applications BiOX (X = Cl, Br and I) photocatalysts efficient photocatalytic degradation (PCD) removal in water/air, such as volatile organic compounds (VOCs), molecule pollutants, polymer biological substances. In addition, hybridization, facet effects mechanisms are highlighted...
Abstract Prompt recombination of photogenerated electrons and holes in bulk on the surface photocatalysts harshly impedes photocatalytic efficiency. However, simultaneous manipulation photocharges two locations is challenging. Herein, synchronous promotion separation photoinduced charges for prominent CO 2 photoreduction by coupling macroscopic spontaneous polarization oxygen vacancies (OVs) BiOIO 3 single crystals reported. The oriented growth single‐crystal nanostrips along [001]...
Two kinds of graphitic carbon nitride (g-C3N4) were synthesized through a pyrolysis process urea or melamine. It is found that the obtained g-C3N4, as photocatalysts, can reduce CO2 to organic fuels under visible light, and exhibit different photoactivity selectivity on formation CH3OH C2H5OH. The product derived from (denoted u-g-C3N4) shows mesoporous flake-like structure with larger surface area higher for reduction than non-porous flaky melamine m-g-C3N4). Moreover, using u-g-C3N4...

Abstract Thin layer fabrication and crystal facet engineering favor the prompt charge transfer from bulk to surface of a material spatial separation among different facets, tremendously benefitting photocatalytic activity. However, thickness composition are considered as two entwined characteristics layered materials with well‐defined tunable shapes, which possess great promise achieve simultaneous manipulation separation. Herein, it is demonstrated that one solution for aforementioned issue...
Black BiOCl with oxygen vacancies was prepared by UV light irradiation Ar blowing. The as-prepared black sample showed 20 times higher visible photocatalytic activity than white for RhB degradation. trapping experiment that the superoxide radical (O(2)(•-)) and holes (h(+)) were main active species in aqueous solution under irradiation.
Solar-energy-driven CO2 conversion into value-added chemical fuels holds great potential in renewable energy generation. However, the rapid recombination of charge carriers and deficient reactive sites, as two major obstacles, severely hampers photocatalytic reduction activity. Herein, a desirable surface halogenation strategy to address aforementioned concerns over Sillén-related layer-structured photocatalyst Bi2 O2 (OH)(NO3 ) (BON) is demonstrated. The halogen ions that are anchored on Bi...
Bismuth-rich bismuth oxyhalides (Bi–O–X; X = Cl, Br, I) display high photocatalytic reduction activity due to the promoting conduction band potential. In this work, two Bi5O7I nanosheets with different dominant facets were synthesized using either molecular precursor hydrolysis or calcination. Crystal structure characterizations, included X-ray diffraction patterns (XRD), field emission electron microscopy and fast Fourier transformation (FFT) images, showed that calcination resulted in...
Phosphorus-doped graphitic carbon nitrides (P-g-C3N4) have recently emerged as promising visible-light photocatalysts for both hydrogen generation and clean environment applications because of fast charge carrier transfer increased light absorption.
