Product Description
Electrocatalytic oxidation is an advanced oxidation technology based on electrochemical principles. It has a wide range of applications in environmental pollution control, energy conversion and other fields. The following is a detailed introduction:
Basic principle: Electrocatalytic oxidation is a catalytic reaction process in which reactant molecules or ions undergo electron transfer on the electrode surface. Under the action of the electric field, organic matter is directly degraded through the anode reaction, or through the anode reaction to produce highly oxidizing intermediates (such as hydroxyl radicals⋅OH, ozone, etc.) to indirectly degrade organic matter. Taking hydroxyl radicals as an example, it has an extremely high oxidation potential (about 2.8V) and can non-selectively mineralize and degrade most organic pollutants into harmless substances such as carbon dioxide and water.
Key components
Electrode materials: It is the core component of electrocatalytic oxidation and directly affects the efficiency and selectivity of the reaction. Common anode materials include lead dioxide (PbO2), boron-doped diamond (BDD), ruthenium dioxide (RuO2), etc. For example, boron-doped diamond electrodes have a wide electrochemical window, low background current, high chemical stability and catalytic activity, and are suitable for the degradation of a variety of organic pollutants; lead dioxide electrodes are relatively low in cost and have certain applications in the treatment of some organic wastewater containing phenols, dyes, etc.
Electrolyte: It plays the role of conducting current in the electrocatalytic oxidation system and affects the reaction process on the electrode surface. Commonly used electrolytes include sodium sulfate (Na2SO4), sodium chloride (NaCl), etc. For example, in an electrolyte solution containing sodium chloride, chloride ions can be oxidized on the anode surface to generate chlorine gas, which is further hydrolyzed to generate hypochlorite. Hypochlorite has strong oxidizing properties and can participate in the oxidation and degradation reaction of organic matter.
Features
High efficiency: It can quickly degrade organic pollutants, has a fast reaction rate and high treatment efficiency, and can make the organic matter in the wastewater meet the discharge standard in a relatively short time.
Flexibility: It can adapt to the treatment needs of different types of organic wastewater by adjusting parameters such as electrode materials, electrolyte types and concentrations, current density, and reaction time.
Environmentally friendly: The electrocatalytic oxidation process generally does not introduce additional chemical reagents, avoiding secondary pollution, and electricity as a clean energy source meets the requirements of sustainable development.
Easy to automate and control: The reaction process can be automated by controlling electrical parameters, which is convenient for industrial application and management.
Application areas
Wastewater treatment: It is widely used in industrial wastewater and domestic sewage treatment, such as pharmaceutical wastewater, printing and dyeing wastewater, electroplating wastewater, etc. It can effectively remove refractory organic matter in wastewater, reduce chemical oxygen demand (COD) and biochemical oxygen demand (BOD), and improve the biodegradability of wastewater.
Drinking water purification: Remove trace organic pollutants, disinfection by-product precursors, etc. in drinking water to ensure drinking water safety.
Energy field: In fuel cells, electrocatalytic oxidation reactions (such as methanol oxidation, ethanol oxidation, etc.) can convert the chemical energy of fuel into electrical energy and improve energy utilization efficiency.
