Abstract Recombination reactions due to poor inter-particle contact at lower temperatures ( 2 sintering to Coble initial stage at low temperatures has been achieved with low melting point zinc (Zn) metal nanoparticles. Zn nanoparticles showed improved inter-particle contact by formation of necks due to high surface diffusion at relatively lower temperatures (200 °C). Addition of Zn nanoparticles showed comparable, rather improved efficiency at 200 °C compared to reference TiO 2 photoanode fabricated at 450 °C due to neck formation and surface plasmonic resonance (SPR) effect. Morphological studies revealed high contact formation between TiO 2 and Zn nanoparticles. Electrochemical impedance and Uv–vis spectroscopy showed improvements in charge transfer and light absorption activity respectively. Structural studies showed no any detectable change in phase due to high surface diffusion and capillary forces produced by Zn nanoparticles at the TiO 2 /Zn interface.

TiO 2 基光阳极的化学烧结，用于使用 Zn 纳米颗粒的高效染料敏化太阳能电池

摘要 由于在较低温度下颗粒间接触不良（2 在低温下烧结到 Coble 初始阶段，低熔点锌 (Zn) 金属纳米颗粒已实现复合反应。Zn 纳米颗粒通过形成颈部而表现出改善的颗粒间接触）在相对较低的温度 (200 °C) 下具有高表面扩散。由于颈部形成和表面等离子体共振 (SPR)，与在 450 °C 下制造的参考 TiO 2 光阳极相比，添加 Zn 纳米颗粒在 200 °C 下显示出相当的、相当提高的效率形态学研究表明 TiO 2 和 Zn 纳米颗粒之间形成高度接触。电化学阻抗和紫外可见光谱分别显示电荷转移和光吸收活性的改善。结构研究表明，由于 Zn 纳米颗粒在 TiO 2 /Zn 界面处产生的高表面扩散和毛细管力，没有任何可检测到的相变化。
