一般描述

TiO2 具有两种物理化学性质不同的主要多晶型物,即锐钛矿和金红石。锐钛矿的光催化活性比金红石更强,但热力学稳定性较低。

应用

TiO2 纳米颗粒被用于研究光催化己烷蒸气降解。它已被用作去除砷的吸附剂。TiO2 纳米颗粒适合作为光催化剂修复废水中的抗菌成分。它还被用于研究二氧化钛纳米颗粒对DNA寡核苷酸的吸附作用。

Dye-sensitized solar cells directly convert sunlight to electricity

Over the last decade, dye-sensitized solar cells (DSSCs) have attracted much attention because these unconventional solar cells exhibit high performance and have the potential for low-cost production.

在过去的十年中,染料敏化太阳能电池 (DSSC) 备受关注,因为此类非常规太阳能电池不仅性能出众,而且还具有低成本生产的潜力。

One of the more traditional photovoltaic devices, single crystalline silicon solar cells were invented more than 50 years ago, currently make up 94% of the market. Single crystalline silicon solar cells operate on the principle of p-n junctions formed by joining p-type and n-type semiconductors.
