  • 摘要: 通过光催化将磷化氢（PH3）分解为黄磷和氢气的技术，兼具环保效益和经济价值.采用化学镀法、化学沉淀法分别在溶胶凝胶法自制的TiO2与商品P25表面负载Ni和Fe3O4，制成钛基负载型催化剂，研究其对PH3光催化分解性能，并利用XRD、EDS、FT-IR、FESEM对催化剂的晶相结构、元素组分、表面官能团及表观形貌等进行表征和分析.结果表明，P25负载型催化剂具有良好的性能，在450℃、395 nm光照条件下，PH3分解率接近100%，光照对催化分解磷化氢具有重要协同作用，应用前景广阔.同时，验证了Ni和Fe3O4是催化剂的高效活性相，对于PH3分解至关重要.
    Abstract: Photocatalytic decomposition of phosphine (PH3) into yellow phosphorus and hydrogen has both environmental and economic benefits. Ni and Fe3O4 supported titanium catalysts were prepared by electroless plating and chemical precipitation, respectively, on the surface of synthesized TiO2 and commercial P25. The photocatalytic decomposition properties of PH3 by the catalysts were studied. XRD, EDS, FT-IR and FESEM were used to characterize and analyze the crystal structure, elemental composition, surface functional groups and apparent morphology of the catalysts. The results suggested that P25 supported catalyst had good catalytic performance. The decomposition rate of PH3 was close to 100% at 450℃ under 395 nm irradiation. The light irradiation plays an important synergistic role in the catalytic decomposition of phosphine and has broad application prospects. At the same time, it was verified that Ni and Fe3O4 were the effective active phases of the catalyst, and they were very important to the decomposition of PH3.
