Electrocatalytic ammonia oxidation reaction (EAOR) provides an ideal solution for on-board hydrogen supply for fuel cells, while the lack of efficient and durable EAOR catalysts has been a long-standing obstacle for its practical application. Herein, we reported that the defect engineering via in-situ electrochem. introducing oxygen vacancies (Vo) not only turns the inactive CuO into efficient EAOR catalyst but also achieves a high stability of over 400 h at a high c.d. of ∼ 200 mA·cm-2. Theor. simulation reveals that the presence of Vo on the CuO surface induces a remarkable upshift of the d-band center of active Cu site closer to the Fermi level, which significantly stabilizes the reaction intermediates (NHx) and efficiently oxidizes NH3 into N2. This Vo-modulated CuO shows a different catalytic mechanism from that on the conventional Pt-based catalysts, paving a new avenue to develop inexpensive, efficient, and robust catalysts, not limited to EAOR. In the experiment, the researchers used many compounds, for example, Cuprichydroxide (cas: 20427-59-2Application In Synthesis of Cuprichydroxide).
Cuprichydroxide (cas: 20427-59-2) belongs to copper catalysts. The applications of Copper-based nanoparticles have received great attention due to low toxicity and inexpensive, earth-abundant. Copper nanoparticles can also catalyze the coupling reaction of nitrogen-containing nucleophiles, phenols, thiols, xanthogenates, selenium ruthenium nucleophiles and the like.Application In Synthesis of Cuprichydroxide
