Abstract: • Successfully loading B-MOFs onto resin for the first time, significantly enhancing their adsorption performance for organophosphorus. • It was discovered that inherent defects are generated during the synthesis of bimetallic MOFs. • The use of 31P NMR and other characterizations has demonstrated that the defects provide Lewis acid sites and a large number of M−OH groups. • DFT theoretical calculations further confirmed that defects can reduce reaction activation energy and enhance selectivity. The inherent defects of bimetallic metal–organic frameworks (B-MOFs) play a significant role in enhancing their performance. The combination of resin with MOFs provides a shortcut for optimizing their structure and adsorption performance. This study developed a simple strategy to control the inherent defects of materials by adjusting the Zr/La precursor ratio to enhance the adsorption performance of Zr-La-MOFs@201 for organophosphorus. To achieve this, we prepared a series of X-Zr-La-MOFs@201 and investigated the impact of different ratios on the degree of defects. Among them, 2-Zr-La-MOFs@201 exhibited a maximum adsorption capacity for organophosphorus of 123.6 mg/g, which is 1.25 and 3.08 times compared to UIO-66@201 and D201, respectively. 31P NMR and TGA results indicated that the performance enhancement primarily stemmed from the increased formation of M P bonds, which differs from the commonly mentioned hydroxyl substitution. DFT calculations showed that the presence of defects effectively reduced the reaction activation energy. In actual water treatment, the maximum treatment capacity of this material reached 5000 BV. This impressive performance demonstrates the potential of Zr-La-MOFs@201 for practical applications in other fields, providing a benchmark for the development of new materials. [ABSTRACT FROM AUTHOR]
