P-N HETEROJUNCTION PHOTOCATALYST, AIR PURIFIER INCLUDING THE SAME, AND METHOD OF PREPARING THE P-N HETEROJUNCTION PHOTOCATALYST - A simplified explanation of the abstract
This abstract first appeared for US patent application 18319760 titled 'P-N HETEROJUNCTION PHOTOCATALYST, AIR PURIFIER INCLUDING THE SAME, AND METHOD OF PREPARING THE P-N HETEROJUNCTION PHOTOCATALYST
Simplified Explanation
The abstract describes a p-n heterojunction photocatalyst used in an air purifier, which generates singlet oxygen upon exposure to energy irradiation to induce photolysis of gaseous pollutants.
- The p-n heterojunction photocatalyst includes a granule type composite with first compound particles and second compound particles on the surfaces of the first compound particles.
- The composite has a size ranging from about 0.9 μm to about 5 μm based on a major axis, with a standard deviation of the size being about ±0.9 μm or less.
- Upon energy irradiation, the composite generates singlet oxygen to break down gaseous pollutants through photolysis.
Potential Applications
The technology can be used in air purifiers for indoor spaces, such as homes, offices, and hospitals, to effectively remove gaseous pollutants and improve air quality.
Problems Solved
The photocatalyst helps address indoor air pollution issues by efficiently breaking down harmful gaseous pollutants, providing a cleaner and healthier indoor environment for occupants.
Benefits
- Improved indoor air quality - Reduction of gaseous pollutants - Healthier living and working environments
Potential Commercial Applications
"Air Purification Technology for Indoor Spaces: Enhancing Air Quality with p-n Heterojunction Photocatalyst"
Possible Prior Art
There may be prior art related to photocatalysts and air purification technologies using similar principles of generating reactive oxygen species to break down pollutants.
Unanswered Questions
How does the photocatalyst compare to other air purification technologies in terms of efficiency and cost-effectiveness?
The article does not provide a direct comparison with other air purification technologies, leaving uncertainty about the relative performance and economic viability of the p-n heterojunction photocatalyst.
What are the specific gaseous pollutants that can be effectively treated by the photocatalyst, and are there any limitations in its pollutant removal capabilities?
The abstract does not specify the types of gaseous pollutants targeted by the photocatalyst or any potential limitations in its pollutant removal capabilities, leaving a gap in understanding the scope of its effectiveness.
Original Abstract Submitted
A p-n heterojunction photocatalyst, an air purifier including the p-n heterojunction photocatalyst, and a method of preparing the p-n heterojunction photocatalyst. The p-n heterojunction photocatalyst includes a granule type composite which includes: first compound particles; and second compound particles on at least a portion of surfaces of the first compound particles, wherein the composite has a size of about 0.9 μm to about 5 μm based on a major axis, a standard deviation of the size is about ±0.9 μm or less, and upon exposure to energy irradiation, the composite generates a reactive oxygen species of singlet oxygen (O) to induce photolysis of gaseous pollutants.
