Photocatalytic Degradation of Acetic Acid Wastewater by Novel Catalysts

With the acceleration of industrialization, acetic acid is an crucial chemical product, and its manufacturing process will create a signifiis able tot quantity of wastewater containing acetic acid. Furthermore These wastewater not only result in serious contamination to the ecological stability, however also pose a risk to the ecological stability. As a environmentally friendly, efficient and sustainable wastewater treatment method, photocatalytic methodology has shown great possible in the treatment of acetic acid wastewater. In recent years, signifiis able tot progress has been made in the research of new catalysts to photocatalytic degradation of acetic acid wastewater. Based on my observations, This article will examine the types, mechanisms and research progress of catalysts.

1. Photocatalytic degradation of acetic acid wastewater basic principle

The core of photocatalytic methodology is to consumption the electronic transition of semiconductor materials under the condition of light, so as to trigger the redox interaction. Under the action of photocatalyst, light energy is absorbed and converted into electron kinetic energy, which in turn decomposes organic contaminants (such as acetic acid) into non-toxic small molecules, such as carbon dioxide and aquatic environments. You know what I mean?. This methodology is able to not only treat acetic acid wastewater efficiently, however also prevent the issue of secondary contamination in traditional treatment methods.

Non-metallic catalysts (such as g-C3N4 and graphene) have shown good performance in the field of photocatalysis due to their unique electronic structure and energy band distribution. From what I've seen, to instance, due to its wide light absorption range and low band gap, g-C3N4 is able to efficiently remove energy in visible light and show high catalytic efficiency in acetic acid degradation. Its catalytic performance is able to be further improved by regulating its structure (such as layered stacking, nitrogen doping, etc. ).
