Abstract: In this paper, BiVO4 monomer was synthesized by hydrothermal method, and modified by polyvinyl alcohol to a porous ceramic carrier prepared by organic foam impregnation method to obtain a BiVO4/porous ceramic composite photocatalyst, and the composition and morphology of the catalyst were characterized by XRD, SEM and other instruments. The results show that the catalyst prepared in this experiment has excellent modification effect, has a low band gap, and improves the utilization rate of sunlight to a certain extent. In addition, the catalyst has high porosity and specific surface area, good wettability to liquid, and can effectively contact with pollutants in liquid, which improves the degradation efficiency. The photocatalytic activity of the catalyst was analyzed by the degradation of methylene blue (MB) solution by using this catalyst. The data showed that when the loading of BiVO4 was 20%, the degradation efficiency of BiVO4/porous ceramics for methylene blue solution within 2.5 h under visible light was as high as 80.83%. Cycling experiments show that BiVO4/porous ceramics have good photocatalytic performance stability, which is due to the efficient recovery of porous ceramic carriers. Therefore, this study is of great significance for the efficient application of photocatalytic technology.Abstract: In this paper, BiVO4 monomer was synthesized by hydrothermal method, and modified by polyvinyl alcohol to a porous ceramic carrier prepared by organic foam impregnation method to obtain a BiVO4/porous ceramic composite photocatalyst, and the composition and morphology of the catalyst were characterized by XRD, SEM and other instruments.

Abstract: The Yangtze River is the largest inland river in the world in terms of freight volume, Developing and applying new materials in the Yangtze River shipping is an important way and method to promote the high-quality development and green low-carbon transformation of the Yangtze River shipping. With the improvement of the control of volatile organic compounds in China, water-based anticorrosive coatings have been widely used in various industries in recent years due to its low toxicity, low flammability and low VOC content. As an important basic material for green development, graphene has many excellent properties, and a number of studies have shown that the addition of graphene to water-based anti-corrosion coatings in a certain way can improve the anti-corrosion performance of the coating. The water-based graphene heavy anti-corrosion coating produced by A company was tested as a new green coating on the buoys of the main line of the Yangtze River. Through testing and analysis in the early stage, the indicators of the coating met the relevant national standards and industry standards. After an 8-month water test, the coating performed well in appearance, color and biological adhesion resistance. Based on this analysis, the feasibility of its extensive application in wharf engineering, channel regulation engineering, ship construction and other Yangtze River shipping facilities and equipment anticorrosion is analyzed.Abstract: The Yangtze River is the largest inland river in the world in terms of freight volume, Developing and applying new materials in the Yangtze River shipping is an important way and method to promote the high-quality development and green low-carbon transformation of the Yangtze River shipping.
