In-situ synthesis of novel p-n heterojunction of Ag2CrO4-Bi2Sn2O7 hybrids for visible-light-driven photocatalysis

Semiconductor-based photocatalysis can utilize solar energy to solve the problems of energy crisis and environmental pollution. How to construct a visible-light-driven (VLD) photocatalyst was the key to efficient use of solar energy. In recent decades, nitrogen (N) resources have attained increasing interest benefit from its outstanding properties and abundant reserves. In addition, nitride and nitrogen-doped (N-doped) photocatalysts have attracted much attention owing to their unique structures, excellent physicochemical stability and low-cost. However, few reviews focus on the nitride and N-doped photocatalysts with high photocatalytic activity. Herein, the critical review summarized the recent progresses and advances in the preparation, properties and applications of nitride and N-doped photocatalysts in hydrogen evolution from water, environmental pollutants removal, carbon dioxide reduction etc. Meanwhile, the current challenges and prospects were also presented. This review aims to summarized the recent researches on nitride and N-doped photocatalysts for environmental applications and energy-related, and provide a constructive guidelines for this booming research topic.

Effects of ball-milling treatment on physicochemical properties and solid base activity of hexagonal boron nitrides

In277S4 nanosheets with the band gap energy of 175 eV were fast prepared via a hydrothermal process The structure, morphology and optical properties of the as-prepared samples were characterized by X-ray diffraction, transmission electron microscopy and UV–vis diffuse reflectance spectroscopy, respectively Rhodamine B, methyl orange and potassium dichromate solution were used to evaluate the degradation efficiency of the as-prepared samples under the visible light, respectively Experimental results showed that the molar ratio of thioacetamide to indium nitrate hydrate significantly influenced the structure and properties of the as-prepared products With increasing the molar ratio, the degradation efficiency of rhodamine B solution was firstly increased and then decreased When the molar ratio was 4:1, the degradation efficiency of the as-prepared sample reached to 96% in 3 min and 100% in 9 min Moreover, this semiconductor could degrade 88% of methyl orange solution in 30 min and 87% of potassium dichromate solution in 60 min, respectively

Boron nitride nanoparticles were prepared in a muffle furnace at 1000 °C by using commercial available boron nitride flakes and sodium chloride as raw materials The structure, functional groups, morphology and specific surface area of the as-prepared samples were characterized by X-ray diffracmeter, fourier-transform infrared spectrometer, transmission electron microscope and accelerated surface area/porosimetry system, respectively In order to evaluate the properties of the as-prepared products, they were mixed with epoxy resin to fabricate polymer-based composites Experimental results showed that the average size and specific surface area of the as-prepared nanoparticles were about 20 nm and 8957 m2/g Moreover, the as-prepared nanoparticles could improve the tensile strength and elongation at break of the epoxy matrix Both of them were first increased and then decreased with increasing the usage amount of the as-prepared nanoparticles When the usage amount of the boron nitride nanoparticles was 04 wt%, the tensile strength and elongation at break of the composites reached to 714 MPa and 221%, which were the maximum values of the composites, respectivley They were increased by 137 and 146% more than those of pure epoxy resin In addition, the as-prepared fillers could accelerate the solidification of the matrix

Boron Nitride Nanoparticles with High Specific Surface Area: Preparation by a Calcination Method and Application in Epoxy Resin

Nanosized Ag2CrO4/few layer boron nitride composites were prepared via in situ precipitation method. The crystal structure, morphology, optical properties, and charge carrier behavior were investigated by X-ray diffraction, transmission electrical microscopy, UV-vis diffuse reflectance spectroscopy, and electrochemical impedance spectroscopy, respectively. The photocatalytic activities of the as-prepared hybrids were discussed by degradation of rhodamine B under visible-light irradiation. Experimental results showed that the average size of pure Ag2CrO4 particles was about 20 nm. Moreover, the degradation efficiency of the as-prepared hybrids was first increased and then decreased with increasing the usage amount of few layer boron nitride nanosheets. When it was 10 wt%, in 120 min, the degradation efficiency of the as-prepared hybrids had reached the maximum of 96.7%. It was much higher than 75% of pure Ag2CrO4 nanoparticles. After 3 cycles of the degradation, the efficiency of the as-prepared composites was decreased from 96.7 to 91.8%. Trapping experiment results revealed that holes played a major role during the photocatalysis process. In addition, electrochemical impedance spectroscopy results indicated that few layer boron nitride nanosheets could enhance the separation and transfer of photogenerated electrons and holes.
