A Novel Ti 12 ‐Based Metal‐Organic Framework for Photocatalytic Hydrogen Evolution (Adv. Energy Mater. 26/2025)

Photocatalytic Hydrogen Evolution MIP-209(Ti) is a new microporous metal-organic framework (MOF) built up from Ti12O15 clusters and substituted terephthalate linkers, enabling isoreticular chemistry and clusters tunability for photocatalytic applications. Cr3+ doping (≤5 at%) on Ti-oxoclusters enhances water stability and markedly boosts hydrogen production from water under simulated solar light irradiation. Significant photocatalytic activity is achieved without noble metals, paving the way for tunable Ti-MOF-based photocatalysts.
