Interfacial Electron Transfer and Synergistic Effects on NiCo(CA)@M Microbars That Boost the Alkaline Oxygen Evolution Reaction

چکیده
The development of oxygen evolution reaction electrocatalysts with a low cost, high activity, and strong stability is great significance to the breakthrough energy conversion technology. Herein, composite material (NiCo(CA)@M) was obtained by growing nickel-cobalt nanoparticles on MIL-88A in situ simple two-step solvent thermal method. results show that NiCo(CA)@M has rich active sites, formation induces charge redistribution between NiCo(CA) MIL-88A, effectively reducing barrier, while growth conducive improvement stability. Impressively, catalyst achieved current density 10 mA cm−2 alkaline electrolyte required an overpotential only 270 mV Tafel slope 69 dec−1. At same time, had excellent at cm−2, after 16 h i-t test, still 91.1% retention. electrocatalytic activity did not decay significantly 2000 CV cycles.

Single-Molecule Kinetics of Interfacial Electron Transfer
Measurements of single-molecule chemical reaction kinetics are demonstrated for interfacial electron transfer from excited cresyl violet molecules to the conduction band of indium tin oxide (ITO) or energetically accessible surface electronic states under ambient conditions by using a far-field fluorescence microscope. In this system, each single molecule exhibits a single-exponential electron ...
