Abstract
The invention belongs to the technical field of waste water processing using solar energy, and in particular to a kind of SiC/C3N4/BiVO4The preparation method of composite photo-catalyst, comprising the following steps: silicon carbide ultrasonic disperse in the aqueous solution of melamine, 10-60min is stirred at 60-100 DEG C, is then cooled down by A., and decompression filters, and obtains solid mixture A；B. it will be ground after solid mixture A drying, be heated to 400-600 DEG C from room temperature under 5-20 DEG C/min, 2-5h is then kept the temperature at 400-600 DEG C, cooling, grinding obtains SiC-C3N4；C. by SiC-C3N4It is added in ammonium metavanadate solution, then bismuth nitrate solution is added in ultrasonic disperse again, adjust the pH to 2-14 of solution, be stirred to react in a water bath, and decompression filters, and obtained mixture B is washed to neutrality, then by mixture B drying, grinding.SiC/C made from method of the invention3N4/BiVO4The light degradation ability of composite photo-catalyst is significantly improved.
Description
Technical field
The invention belongs to the technical field of waste water processing using solar energy, and in particular to a kind of SiC/C3N4/BiVO4It is compound
The preparation method of photochemical catalyst.
Background technique
The abundant and effective supply of the energy is to ensure the national economic development, and (" coal is more for the fundamental safeguarded national security
Co-production technology and Hydrogen Technology ", Xiao Yunhan etc., North China Electric Power University's journal are the 6th phase of volume 31 in 2004, the 5-9 pages, open
On November 30th, 2004 day).It is that the whole world disappears using coal, oil and natural gas as the fossil energy of representative over the past decades
The main energy of consumption.However, long-term exhaustive exploitation causes fossil energy increasingly withered with the development of economy and human society
It exhausts, in addition the production of the energy, conversion and use bring serious environmental pollution, ecosystem destruction and climate change etc. are asked
Topic constitutes serious threat (" new energy strategy and national economy sustainable development ", Lee to the survival and development of mankind itself
Fine jade, Chinese collective economy, the 5th phase in 2017, the 29-31 pages, publication date on 04 06th, 2017；" coal poly-generation technology and
Hydrogen Technology ", Xiao Yunhan etc., North China Electric Power University's journal, the 6th phase of volume 31 in 2004, the 5-9 pages, publication date 2004 years 11
The moon 30).Simultaneously as the sharp increase of the size of population, the random row of modern industry waste water left about, municipal refuse, rural area pesticide
Sprinkling etc., causing is already few freshwater resources aggravation shortage, and wherein dyeing is all to cause water all the time
(" solving dyeing water pollution problems by technological progress ", Sun Ruizhe etc., environment is protected in pollution problem more serious source
Shield, the 19th phase in 2007, the 33-35 pages, publication date on December 31st, 2007；" dyeing water pollution control technical problem with
It is recommended that ", Zhang Qiongfang, the economic guide of science and technology, the 27th phase in 2016, page 80, publication date on December 31st, 2016).Moreover, dyestuff
Waste water has that complicated component, coloration are high, concentration is big, strong toxicity, hard-degraded substance are more, water quality and quantity fluctuates big and unstable etc. spies
Point, current dye species increase in addition, and have the characteristics that anti-light solution, anti-oxidant, antibiooxidation mostly, to increase dye
Expect processing difficulty (" the composite photocatalyst Co of waste water2+/TiO2Degradation dye wastewater methylene blue ", Wan Xiang, Jiangsu are big
Learn master thesis, 2010, page 1, publication date on October 31st, 2010；" it is useless that Fenton oxidation handles methyl orange dye
The research of water ", sudden and violent refined refined, Jiangsu University's master thesis, 2006, page 2, publication date on December 31st, 2006).
Treatment method of printing and dying wastewater can be divided into physical method, chemical method and biochemical method three categories.Wherein, physical method passes through suction
