The benchmarking of the performance for H2 evolution cobalt diimine-dioxime catalysts is provided based on a comprehensive study their catalytic mechanism. latter follows an ECE'CC pathway with intermediate formation Co(II)-hydride and second protonation possibly at basic site ligand, acting as proton relay. This suggests intramolecular coupling between hydride protonated ligand concentration-i...

A poly(vinyl chloride) membrane based on a new a-dioxime derivative as membrane carrier was prepared andinvestigated as a Cr(III) selective electrode. The electrode exhibits a good potentiometric response for Cr(III)over a wide concentration range 1.0 x 10-6 to 1.0 x 10-1 M with a slope 19.5+0.5 mV/decade and low detectionlimit of 8.9 x 10-7 M. It has a fast response time < 15 s. The best perfo...
