通过微波诱导组装法制备了直径为80~120 nm的新型磁性载铂纳米链，并对其进行了电偶置换性能研究。铂纳米粒子分布在NiCo纳米链的表面。产品作为潜在的氢能应用的水解脱氢催化剂进行了研究。与NiCo纳米链相比，负载铂的NiCo纳米链在常温常温下对氨硼水溶液的水解脱氢表现出极高的催化活性，其中Ni16Co80/Pt4纳米链具有较高的催化活性，其活化能为45.72kJ·−-1，脱氢速率为1.17m×104mL.min-−-1g-−-1，这表明其在氢燃料和化工领域具有潜在的应用前景。
A new magnetic Pt-loaded NiCo nanochain, with the diameter from 80 nm to 120 nm, has been prepared through microwave-induced assembly process followed by the galvanic displacement performance. Pt nanoparticles are distributed on the surface of NiCo nanochains. The products are investigated as hydrolytic dehydrogenation catalyst for potential hydrogen energy applications. Compared with NiCo nanochains, the Pt-loaded NiCo nanochains present exceedingly high catalytic activity toward the hydrolytic dehydrogenation of ammonia borane aqueous under ambient atmosphere at room temperature, where the Ni16Co80/Pt4nanochains exhibit high catalytic activity with a lower activation energy of 45.72 kJ mol−1and a superior dehydrogenation rate of 1.17 × 104mL min−1g−1, suggesting the potential application in hydrogen fuel and chemical industry.
