The book reviews the fundamentals of advanced oxidation processes (AOPs) technologies to degrade hazardous organics via photocatalysis of 1-dimensional zinc-oxide (ZnO). One-dimensional ZnO nanorods (ZnO-NRs) have been of utmost interest due to their high surface area, efficient charge transport, and superior photosensitivity. These features make ZnO-based nanorods exciting candidates for applications in photocatalysis. Even though photocatalysis using bare ZnO nanorods is useful in pollut...
