摘要
创造高效,地球丰富的电催化剂是解决缓慢的析氧反应动力学(OER)的关键。在本研究中,采用直接浸渍技术将Fe(OH)3纳米颗粒包埋在NiZn LDH纳米片上,制备了NiZnFex LDH复合材料。优化后的NiZnFe12.9 LDH催化剂在10 mA cm−2下的过电位仅为191 mV,显著优于传统的OER催化剂。此外,它表现出优异的长期稳定性,保持120毫安厘米−2的电流密度超过125小时。这种方法促进了水分解和制氢材料的进步,这对可持续能源解决方案至关重要。
Decorated high-dispersity Fe(OH)3 nanoparticles on NiZn LDH nanosheets towards enhanced alkaline oxygen evolution reaction†
The creation of efficient, earth-abundant electrocatalysts is crucial to address the sluggish kinetics of the oxygen evolution reaction (OER). In this study, a straightforward immersion technique is employed to fabricate a NiZnFex LDH composite by embedding Fe(OH)3 nanoparticles onto NiZn LDH nanosheets. The optimized NiZnFe12.9 LDH catalyst exhibits an overpotential of just 191 mV at 10 mA cm−2, significantly outperforming traditional OER catalysts. Additionally, it demonstrates exceptional long-term stability, maintaining a current density of 120 mA cm−2 for more than 125 hours. This approach fosters the advancement of materials for water splitting and hydrogen production, which are crucial for sustainable energy solutions.
