An effective method was developed for preparing highly dispersed nano-sized Pt–Sn/C electrocatalyst synthesised by a modified polyol reduction method. From XRD patterns, the Pt–Sn/C peaks shifted slightly to lower 2θ angles when compared with commercial Pt/C catalyst, suggesting that Sn formed alloy with Pt. Based on HR-TEM images, the Pt–Sn/C nanoparticles showed small particle sizes and well dispersed...
A study of the electrochemistry of mercury and organo mercury complexes with cysteine indicated the formation of stable complexes which can be utilized for the determination of the species in environmental matrices. A technique based on capillary electrophoresis and amperometric detection (CE–AD) has been developed for the speciation of mercury with a newly developed cross hair design electrochemical...
