This book presents a wide range of synthesis and characterization techniques to produce ceramic nanomaterials specially developed to be used in environmental applications. The book cover synthesis using hydrothermal, chemical vapor deposition, sol-gel, emulsification, magneto-sputtering, among other process and modern characterization techniques with detail. The use of the synthesized materials in eco-friendly approaches such as photocatalysis, solar energy efficiency improvement, absorbents, sensors, solar cells, biofuels and waste reuse are reported in detail.

Annelise Kopp Alves is a Professor at the Materials Department of the Universidad e Federal do Rio Grande do Sul (UFRGS) since 2010. From 2012 to 2016 she was the Head of the Materials Department at UFRGS. From 2016 to 2017 she was the Coordinator of the Materials Engineering course at UFRGS. Her research is focused on nanometric ceramic materials applied to catalysis and energy.
