Here, we find that B-doped TiO_2-x prepared via a one-pot method exhibit excellent performance on adsorption and photodegradation of various dyes. The B-doping extends the light absorption edge to 520 nm and its major role is the adsorption of organic dyes, while Ti³⁺-doping is responsible for the light response at 500–800 nm and > 800 nm and contributes more for the dye degradation. >15 dyes were investigated and high adsorption efficiency was achieved for cationic dyes without -COOH/-SO₃H groups. Besides electrostatic adsorption, direct bonding of = N⁺(CH₃)₂ with B/B-O sites play an important role in enhancing the adsorption capability.

在这里，我们发现通过一锅法制备的B 掺杂 TiO _{2-x在各种染料的吸附和光降解方面表现出优异的性能。}B-掺杂将光吸收边扩展到520 nm，主要作用是吸附有机染料，而Ti ³⁺掺杂负责500-800 nm和> 800 nm的光响应，对染料的贡献更大降解。研究了超过 15 种染料，并且对于不含 -COOH/-SO ₃ H 基团的阳离子染料实现了高吸附效率。除静电吸附外，=N ⁺ (CH ₃ ) ₂与B/BO位点的直接键合对提高吸附能力也起着重要作用。
