Focus of the figure: This study explored the use of metal oxide‐based nanoparticles for the photocatalytic degradation of agro‐organochlorine pollutants. It highlighted how supporting or doping these nanoparticles reduces electron‐hole recombination, introduces new Fermi levels and Schottky barriers, and enhances photocatalytic efficiency. Finally, ways to improve the performance of metal oxide‐based nanoparticles were discussed. More details about this figure will be discussed by Dr. Stephen S. Emmanuel and his co‐workers on pages 265–305 in this issue. image
