Showcasing research from a group of researchers led by Dr. Ji-Soo Jang from Korea Institute of Science and Technology (KIST), Dr. Donghwi Cho and Dr. Jeong-O Lee from Korea Research Institute of Chemical Technology (KRICT), Prof. Seokwoo Jeon from Korea University. 

This work reports the rational design of ultra-small (< 5 nm) polyelemental nanocatalysts on a 3D TiO2 nanostructure by an ultrafast fl ash lamp-driven photothermal shock, enabling instant reduction of surface decorated, metal ionic precursors into the atomically mixed heterostructure. The exceptional photocatalytic eff ect of the material system demonstrates dual-modal chemical detection and neutralization of environmental pollutants.
