| 中文摘要: |
| 采用染料曙红-Y（EY）作为敏化剂将Ni2+光还原制备纳米Ni.在该反应体系中，不加入PVA时，光还原所得到的纳米Ni为球状粒子；而加入PVA，由于其模板导向作用，多数纳米镍呈现棒状.吸附在Ni表面的PVA能够促进光生电子从EY向棒状镍转移，从而提高其染料敏化制氢的活性和稳定性. |
| 英文摘要: |
| Ni nanoparticles were fabricated by photoreduction of Ni2+ using dye eosin-Y as a sensitizer. In this reaction system, in the absence of PVA sphere-like Ni nanoparticles were obtained by the photoreduction; whereas in the presence of PVA, due to its template guiding role, the prepared Ni nanoparticles showed rod-like morphology. The PVA adsorbed on rod-like Ni nanoparticles can promote the transfer of photoinduced electrons from eosin-Y to Ni, leading to increase of the activity and stability of the dye-sensitized photocatalytic hydrogen production. |
