The field of room-temperature corrosion engineering has emerged as a promising avenue for the controlled synthesis of functional nano-materials, owing to its simplicity and potential for scalability. To date, room temperature corrosion engineering has been skillfully applied and successfully used to synthesizee transition metal (oxy)hydroxides. However, the synthesis of transition metal sulfides via room-temperature corrosion encounters challenges due to the low standard electrode potential and sluggish corrosion kinetics of S/Sn2-. Here, we have successfully initiated the oxidation behavior o...
