Hypothesis
Can a novel high-entropy metallene catalyst improve the efficiency of ethanol oxidation reactions?
Conclusion
The high-entropy PdRhFeCoMo metallene exhibits excellent performance in ethanol oxidation with high C1 selectivity and resistance to poisoning.
Supporting Evidence
- The PdRhFeCoMo HEM shows a mass activity of 7.47 A mgPd+Rh −1.
- It retains a mass activity of 0.56 A mgPd+Rh −1 after 20,000 seconds of testing.
- The C1 selectivity of the catalyst reaches up to 84.12%.
- The flexible solid-state ethanol fuel cell demonstrates a maximum power density of 20.1 mW cm−2.
Takeaway
Scientists created a new type of catalyst that helps turn ethanol into energy more efficiently and doesn't get easily damaged.
Methodology
A two-dimensional high-entropy metallene was synthesized using a mild one-step solvothermal method.
