We report here the application of “preanodized” screen printed carbon electrode without the need of adding catalysts for the adsorption and subsequent oxidation of polyaromatic hydrocarbons (PAHs). By suitably defining the preanodization conditio

Loading metal nanoparticles on the surface of nanosheet supports is an attractive approach to enhancing their catalytic performance. Herein, palladium nanoflowers (Pd NFs) were prepared on amino-functionalized fullerene (C60-NH2) by hydrothermal self

Many fluoroorganic compounds are toxic and persistent, and achieving their efficient degradation under mild conditions is currently a challenge. Herein, we developed a new electrochemical hydrodefluorination (HDF) system based on rhodium electrocatal
