Environmental Catalysis discusses about the fundamentals of environmental catalysis. This book brings together the highlights on the topics such as environmental catalysis of stationary sources. The information about the testing of the SCR catalyst, which allows the readers to gather information about the most accurate projection of the remaining catalysts done by engineers, has been covered in this book. This book introduces the readers to the combustion catalysis and metals and oxyanion. It also covers the topics such as catalysis of electron transfer reactions and precipitation and dissolution. There are some techniques for the non – linear, which is used to characterize the strength of non-linear optical response, has been discussed in this book. This book provides readers with the insights related to the new developments taking place in the environmental catalysis.
