Understanding electrochemical sub-processes occurring at solid oxide cells (SOCs) components, mainly air electrodes, is of high importance since they play a key role in improving the performance SOC devices and their durability. Among various analysis methods, impedance spectroscopy (EIS) most used one studies. However, analyzing interpreting EIS data have always been considered as challenge given fact that information provided by common approach complex non-linear least square (CNLS) method limited. Viewed this sight, distribution relaxation time (DRT) has gained considerable attention recent years potential to analyze measurement results.

Effective catalytic removal of 4-nitrophenol (4-NP) in industrial wastewater remains a significant challenge due to the lack highly efficient and stable catalysts. Herein, we demonstrated promising plasma method for facile, ultra-fast low-temperature synthesis graphite oxide (GO)-supported palladium catalyst (Pd/GO-P) rich oxygen-containing groups (OCGs) defects with smaller Pd nanoparticles (NPs) 4-NP reduction. The limited damage OCGs retained more (mainly alkoxy hydroxyl groups) on GO surface. In addition, treatment can increase active sites density surface defects. These promoted adsorption improved dispersion aqueous solution 4-NP, thereby enhancing reduction performance. Pd/GO-P showed highest reported thus far, concentration-normalized rate constant 5576 min−1 g−1 L. This value was 51.6 20.5 times greater than that using Pd/rGO-H prepared by traditional thermal commercial Pd/AC catalyst, respectively. work opens avenue exploring use rational design supported catalysts superior performance recycling wastewater.
