The separation entails a two‐stage anion‐exchange procedure. In the first stage, Pt and Pd are separated from each other and from major matrix constituents including Fe and Ni. In the second stage, Ir is reduced with ascorbic acid and eluted from the column before Pt collection. Platinum yields for the total procedure were typically 50–70%.

Electrocatalytic performance of low-cost graphitic carbon nitride (g-C3N4) is greatly limited by its conductivity. In this work, an innovative method, gamma irradiation technology, was used to efficiently synthesize g-C3N4/Pt nanoparticle (CN/Pt) nanocomposites, which can construct conductive channels between the nanostructure g-C3N4 and supported platinum nanoparticles (PtNPs). Then, the as .
