Defect-containing metal–organic framework materials for sensor applications
Literature Information
Dahui An, Long Chen, Yun Liang, Juan Hou
Defective metal–organic framework (MOF) materials exhibit remarkable potential across diverse fields such as adsorption, electrocatalysis, and electrochemical sensors due to their exposed massive active sites, defective microstructure, exceptional porosity, substantial specific surface area, and unoccupied metal ligand sites. Herein, the working principles of defect construction, defect mechanism, and defect application of MOFs are first briefly summarized. Therefore, this review enables researchers to be inspired to design defective MOFs for electrochemical sensor applications, which is analyzed to establish a relationship between defect construction, electronic structures, and electrocatalytic performance. To address the current challenging issues of electrochemical sensors, various emerging defect strategies are finally prospected and potential avenues for utilizing defects to enhance sensor technologies are pointed out, providing valuable references for future research.

Journal of Materials Chemistry A

Journal of Materials Chemistry A, B & C cover high quality studies across all fields of materials chemistry. The journals focus on those theoretical or experimental studies that report new understanding, applications, properties and synthesis of materials. The journals have a strong history of publishing quality reports of interest to interdisciplinary communities and providing an efficient and rigorous service through peer review and publication. The journals are led by an international team of Editors-in-Chief and Associate Editors who are all active researchers in their fields. Journal of Materials Chemistry A, B & C are separated by the intended application of the material studied. Broadly, applications in energy and sustainability are of interest to Journal of Materials Chemistry A, applications in biology and medicine are of interest to Journal of Materials Chemistry B, and applications in optical, magnetic and electronic devices are of interest to Journal of Materials Chemistry C. More than one Journal of Materials Chemistry journal may be suitable for certain fields and researchers are encouraged to submit their paper to the journal that they feel best fits for their particular article. Example topic areas within the scope of Journal of Materials Chemistry A are listed below. This list is neither exhaustive nor exclusive. Artificial photosynthesis Batteries Carbon dioxide conversion Catalysis Fuel cells Gas capture/separation/storage Green/sustainable materials Hydrogen generation Hydrogen storage Photocatalysis Photovoltaics Self-cleaning materials Self-healing materials Sensors Supercapacitors Thermoelectrics Water splitting Water treatment
