The specialized book "Photodegradation of Cu(II) Soaps derived from Edible & Non Edible Oils" offers a comprehensive study of photocatalysis and its applications in various fields, including energy, environment, and technology. It highlights the synthesis of copper(II) soaps derived from saturated fatty acids as well as from edible and non-edible oils. The work also includes spectroscopic studies conducted to analyze the structure of these soaps. A central theme is the photocatalytic decomposition of these soaps in the presence of semiconductors, providing important insights for waste treatment and pollution control. The investigation of decomposition under various conditions, including influencing factors such as soap concentration and light intensity, is also addressed. This book is aimed at professionals and students in the fields of chemistry, environmental sciences, and engineering.
