Application of in situ synthesis of H2O2 in water treatment technology:a review

Hydrogen peroxide(H₂O₂)can degrade most of organic pollutants in water by producing hydroxyl radicals(·OH).Using in-situ synthesis of H₂O₂ in water treatment technology can not only save cost,but also improve the synthesis and utilization rate of H₂O₂,which is also the current research direction and goal.In this review,from the point of view of the in-situ generation method of H₂O₂,the research on the treatment of pollutants in water by in-situ synthesis of H₂O₂ in recent years was summarized.It was analyzed that the utilization ratio of different hydrogen sources in different catalytic environment is different;the different synthetic materials and synthetic technology of catalyst also have a great influence on the adsorption and degradation ability of catalyst;the external factors such as p H value and temperature are all important factors that may limit the ability of catalyst.At the same time,the challenge and development prospect of in-situ synthesis of H₂O₂ in water treatment field were prospected,so as to provide guidance and reference for large-scale practical application of the technology.
