In this research, polyaniline/graphitic carbon nitride (PANI/g-C₃N₄) nanocomposites were synthesized via in-situ electrochemical polymerization of aniline monomer whit different number of cyclic voltammetry scans (10, 20 and 30 cycles) after electrode surface pre-preparation using a potential shock under ultrasonic irradiation. PANI/g-C₃N₄ nanocomposites with two values of g-C₃N₄ (0.010%w and 0.015%w) were deposited on the surface of the transparent conducting film (FTO glass) by immersing FTO into the aniline solution and g-C₃N₄ during the electro-polymerization. The resulting PANI/g-C₃N₄ films were characterized by Fourier transformed infra-red (FTIR), power X-ray diffraction (PXRD), field emission scanning electron microscopy (FE-SEM) and transmission electron microscopy (TEM) techniques. The prepared electrodes were applied as counter electrode in dye-sensitized solar cells. Among them, the prepared electrode with 10 cycles and 0.01%w g-C₃N₄ showed the best efficiency. These hybrids show good catalytic activity in elevating tri-iodide reduction and due to the synergistic effect of PANI and g-C₃N₄, PANI/g-C₃N₄ nanocomposite electrode shows power conversion efficiency about 1.8%.

在这项研究中，聚苯胺/石墨碳氮化物（PANI / gC ₃ N ₄）纳米复合材料是通过在电极表面预备后进行不同数量的循环伏安扫描（10、20和30个循环）后，通过苯胺单体的原位电化学聚合而合成的在超声辐射下使用潜在的冲击。通过将FTO浸入苯胺溶液和gC ₃ N _4中，将具有两个gC ₃ N ₄值（0.010％w和0.015％w）的PANI / gC ₃ N ₄纳米复合材料沉积在透明导电膜（FTO玻璃）的表面上。在电聚合过程中。所得的PANI / gC ₃ N ₄通过傅立叶变换红外（FTIR），功率X射线衍射（PXRD），场发射扫描电子显微镜（FE-SEM）和透射电子显微镜（TEM）技术对薄膜进行了表征。将制备的电极用作染料敏化太阳能电池中的对电极。其中，制备的具有10个循环和0.01％w gC ₃ N _4的电极显示出最佳的效率。这些杂化物在提高三碘化物还原方面显示出良好的催化活性，并且由于PANI和gC ₃ N ₄的协同作用，PANI / gC ₃ N ₄纳米复合电极显示约1.8％的功率转换效率。
