A research team at the University of Sussex in the UK recently published its latest study in the journal Results in Chemistry, systematically comparing the electrocatalytic performance of three noble metals—platinum, palladium and ruthenium—in multi-walled carbon nanotube (MWCNT) composite electrodes. The study found that palladium black delivers better sensitivity than platinum black in hydrogen peroxide detection, while platinum black holds a distinct advantage in nitrite detection. The findings offer a new material design direction for next-generation medical diagnostics, biosensing and environmental monitoring technologies.
