The existence of infrared radiation was first discovered by Sir William Herschel in the early 19th century. While conducting an experiment to measure the temperature of different colors of light (from sunlight passed through a prism), Herschel observed that the region beyond the red light had the highest temperature. This led him to the discovery of infrared radiation, a form of light invisible to the human eye but detectable due to the heat it produced.
Evolution of Catalysis
The concept of catalysis dates back to ancient times, with early civilizations using naturally occurring catalysts for processes like fermentation. However, the term “catalysis” was coined by Jöns Jacob Berzelius in the early 19th century. Berzelius recognized that certain substances could facilitate chemical reactions without being consumed in the process. This understanding laid the foundation for modern catalytic processes.
Industrial Revolution and Heating Needs
The Industrial Revolution in the 18th and 19th centuries saw a surge in the need for efficient heating solutions. Traditional methods were often inefficient and polluting. The discovery and understanding of infrared radiation and catalysis provided industries with new avenues to explore more efficient and cleaner heating solutions.
20th Century Advancements
The 20th century saw significant advancements in the application of infrared and catalytic technologies. Industries began to harness the power of infrared radiation for various applications, from drying paints to food processing. Similarly, the principles of catalytic oxidation were refined and applied in various sectors, from automobile exhaust systems to industrial heaters.
