“…Recently, the synthesis of bimetallic MOF with heterogeneous metal clusters has been attempted to attain superior adsorption and catalytic performance by manipulating the arrangement of metal nodes and creating the purposeful crystal defect. − Detailed characterization and theoretical investigations demonstrate that altering the type of metal clusters within the secondary building units (SBUs) of MOFs induces electronic interference in metal clusters. , This electronic interference offers the ability to finely tune the band structure, effectively adjusting the conduction band (CB) energy and the valence band (VB) energy to align with the redox potentials of •O 2 – and •OH – radicals, resulting in an enhanced quantum yield. ,, More prevalently, lowering the band gap energy has been pursued for effective photocatalytic activity under visible light; however, simple repositioning of CB and VB can cause undesired electron–hole recombination, leading to poor light utilization and sluggish reaction kinetics. − Thus, further refinements of band energy modification considering complex electron–hole interactions are necessary to overcome such constraints for effective photocatalytic application. , …”
