title: Tailoring the Optical Absorption of Water-Stable Zr(IV)- and Hf(IV)-Based Metal-Organic Framework Photocatalysts.
abstract: New Zr(IV)- and Hf(IV)-based metal-organic framework photocatalysts, termed VNU-1 and VNU-2 (where VNU = Vietnam National University), were synthesized and their resulting structures fully characterized. By employing a highly π-conjugated linker, namely 1,4-bis(2-[4-carboxyphenyl]ethynyl)benzene, the optical absorption properties were effectively red-shifted into the visible light region. This strategy, coupled with the high water stability of the materials, led to enhanced MOF-driven photocatalytic degradation, under ultraviolet-visible light, of organic dye pollutants commonly found in wastewater.
