Self-assembled ZnO microspheres coated with carbon dot-doped CoNi LDH wrinkled films as electrochemical sensors for highly sensitive detection of hydrazine

Surface folded composites were prepared in situ using CoNi LDH hybrid films loaded with nitrogen-doped carbon dots on self-assembled ZnO microspheres (ZnO@CoNi LDH-NCDs). It acts as an electrode which has excellent sensing performance for hydrazine.
