我们首次提出了使用尺寸约为100 nm的束状3D金红石TiO 2颗粒（3D BR-TiO 2）通过烧结方法获得1D TiO 2纳米棒的合成方法。本研究的目的是（i）通过烧结过程控制两种TiO 2半导体纳米晶体的混合物在FTO衬底上的结晶，即3D BR-TiO 2和球形TiO 2（SA-TiO 2）;（ii）建立一种新的方法来制造染料敏化太阳能电池（DSSC）中的光阳极。此外，我们还致力于采用“水基”纳米流体制备低成本、环境友好的二氧化钛电极。我们的研究结果为如何通过烧结技术将众多的3D TiO 2颗粒重塑为1D TiO 2基电极来提高光伏性能提供了有用的指导。
We present for the first time a synthetic method of obtaining 1D TiO2nanorods with sintering methods using bundle‐shaped 3D rutile TiO2particles (3D BR‐TiO2) with the dimensions of around 100 nm. The purpose of this research is (i) to control crystallization of the mixture of two kinds of TiO2semiconductor nanocrystals, that is, 3D BR‐TiO2and spherical anatase TiO2(SA‐TiO2) on FTO substrate via sintering process and (ii) to establish a new method to create photoanodes in dye‐sensitized solar cells (DSSCs). In addition, we focus on the preparation of low‐cost and environmentally friendly titania electrode by adopting the “water‐based” nanofluids. Our results provide useful guidance on how to improve the photovoltaic performance by reshaping the numerous 3D TiO2particles to 1D TiO2‐based electrodes with sintering technique.
