As urbanization and industrialization increase, the quality of life gradually declines, and traditional industrial waste treatment methods lead to increased hazards of groundwater, fos sil fuels, and air, adversely affecting human and animal health.
In industrial waste, dyes and volatile organic compounds play an important role in water and air pollution. Advanced oxidation processes are used to remove organic pollutants from water and air. Heterogeneous photocatalysis is an efficient and Low-cost AOP and is also considered one of the top technologies for removing organic pollutants from water and air.
Metal oxide semiconductor photocatalysts have unique physical and chemical properties, non-toxicity, and excellent photocatalytic activity, so they are widely used in the field of environmental cleaning. Titanium dioxide is a photocatalyst that has attracted much attention because of its low cost, non-toxicity and Chemically inert.
Since it can only absorb ultraviolet light and has a low utilization rate of visible light, effective design, and synthesis, visible-light-driven photocatalysts have become an important research field. Some metal oxides, such as La2O3, CdO, CeO2, CaO and ZnO, etc. It is considered a promising synergistic catalyst that can be used in combination with TiO2 to improve the efficiency of photocatalytic reactions.
Through development and research, these new photocatalytic materials and technologies can process industrial waste more effectively, reduce damage to the environment, improve the quality of life, and protect ecosystems and human health.
Nanostructured spinel-like ferrites are considered to be very promising and efficient photocatalyst candidate materials. They are low-cost, easy to produce, and have unique magnetic characteristics. In the photocatalytic process, spinel-like ferrites Spar ferrites can absorb photons from a light source and form electron-hole pairs, thereby generating active superoxide radicals.
Spinel-like ferrite has great advantages in constructing magnetic photocatalyst nanocomposites. By combining CdTiO3 with magnetic spinel-like copper ferrite nanoparticles, the light-induced charge separation effect can be improved, thereby producing powerful photocatalytic activity.
Copper ferrite has attracted much attention for its potential applications in several fields, such as electronics, sensors, drug delivery, magnetic memory, and high-frequency devices. CuFe2O4 has low cost, good photochemical stability, and excellent magnetic properties and optical properties. Due to its responsiveness and other advantages, it is considered a potential photocatalytic and photoelectrocatalyst.
Copper ferrites are widely studied and used in many applications due to their compelling electronic, thermal, magnetic, and catalytic properties. Silver, a substance added to the material, has attracted considerable interest recently. It can improve the activity of semiconductor photocatalysts and decrease the recombination rate of electrons and holes generated during the photocatalytic process.
By changing or reducing the energy of the band gap, silver-doped materials can increase the activity of photocatalysts under visible light. Graphene is a promising two-dimensional material with many special properties, including excellent mechanical, electrical, and thermal properties. , and large surface area.
To reduce graphene oxide to graphene with an aromatic structure, doping materials, and rGO can form composite materials, which can effectively reduce the recombination rate of electrons and holes and promote the transfer of charges using Copper ferrite and activated carbon fibers were synthesized by precipitation method, and ACF@rGO composite materials were prepared by ultrasonic method.
The decomposition process of these photocatalysts on colored and colorless organic wastewater under sunlight was studied, and the mechanism of photocatalysis was explored. It has important application value in wastewater treatment and realizes the synthesis of silver-copper ferrite and rGO. The nanocomposite was prepared, and its cycling stability and photodegradability were improved when the composite was formed.
First, you need to prepare a copper nitrate solution and an iron nitrate solution. Dissolve 0.01 mol of copper nitrate in 100 mL of distilled water, and dissolve 0.02 mol of iron nitrate in another 100 mL of distilled water.
Next, mix the two solutions and stir for 30 minutes under strong magnetic stirring. In order to increase the pH value of the solution, add an appropriate amount of ammonia water and continue stirring for 30 minutes. Then stop stirring.
