摘要：

metal oxide nanostructures with single-atomic heteroatom incorporation are of interest for many applications. however, a universal and scalable synthesis approach with high heteroatom concentrations represents a formidable challenge, primarily due to the pronounced structural disparities between m_hetero–o and m_sub–o units. here, focusing on tio₂ as the exemplified substrate, we present a diethylene glycol-assisted synthetic platform tailored for the controlled preparation of a library of m₁-tio₂ nanostructures, encompassing 15 distinct unary m₁-tio₂ nanostructures, along with two types of binary and ternary composites. our approach capitalizes on the unique properties of diethylene glycol, affording precise kinetic control by passivating the hydrolytic activity of heteroatom and simultaneously achieving thermodynamic control by introducing short-range order structures to dissipate the free energy associated with heteroatom incorporation. the m₁-tio₂ nanostructures, characterized by distinctive and abundant m–o–ti units on the surface, exhibit high efficiency in photochromic photothermal catalysis toward recycling waste polyesters. this universal synthetic platform contributes to the preparation of materials with broad applicability and significance across catalysis, energy conversion, and biomedicine.
