It is shown that the reduction of the entropy by removal of a single element leads to a completely different electrochemical behavior and cycling degradation. Additionally, unique possibilities to fine-tune the electrochemical performance of high-entropy materials is demonstrated, by making use of the...
These results further support the advantages of high-entropy alloy NPs-loaded catalysts in terms of high intrinsic activity and low metal leaching in addressing environmental pollution. Furthermore, monitoring the PMS consumption rate via the iodine reduction reaction suggested that the exceptional ...

Entropy stabilization can be discussed by considering the free energy in a metallic system according to Eq. (1) [10]. A single phase will form only when mixing leads to a reduction in Gibbs free energy, thus when the free energy of mixing ΔGmix (in J/mol) is negative, where(1)∆...
The oxygen reduction mechanism was found to change with the applied potential. At low overpotential, the oxygen reduction required two electrons to produce H2O2; whereas at high overpotential, the produced H2O2 was further reduced into H2O [30]. Belkessam et al. found that Cl-NiCoO showed ...

Moreover, with nitrate reduction as coupling cathode reaction, SC-MHEO realizes concurrent electrosynthesis of value-added FDCA and ammonia in the two-electrode cell. Our study provides a powerful paradigm for producing a library of novel mesoporous single crystals for important catalysis-related ...
