Summary

Two novel titanium-oxide clusters (TOCs) were synthesized. One cluster demonstrated significantly enhanced hydrogen evolution activity, nearly eight times greater than the other, due to induced platinum nanoparticle assembly.

Area of Science:

  • Inorganic Chemistry
  • Materials Science
  • Nanotechnology

Background:

  • Titanium-oxide clusters (TOCs) are of interest for catalytic applications.
  • Controlling the structure and assembly of nanomaterials is crucial for optimizing their performance.
  • Hydrogen (H2) evolution is a key process in sustainable energy technologies.

Purpose of the Study:

  • To synthesize and characterize novel nanosized titanium-oxide clusters.
  • To investigate the structure-activity relationship of TOCs in hydrogen evolution.
  • To elucidate the mechanism behind enhanced catalytic activity.

Main Methods:

  • One-pot synthesis utilizing 2-picolinic acid and Ti(O^iPr)_4.
  • Single-crystal X-ray diffractometry for structural determination.
  • Hydrogen evolution activity measurements and mechanistic studies.

Main Results:

  • Two TOCs, Ti12(μ2-O)14(μ3-O)4PA16 (1) and Ti12(μ2-O)18PA18 (2), were successfully synthesized.
  • Cluster 1 exhibited superior H2 evolution activity (180 μmol h-1 g-1), approximately eight times higher than cluster 2.
  • Mechanistic studies showed cluster 1 induces the assembly of platinum nanoparticles (PtNPs) into larger structures, enhancing H2 evolution.

Conclusions:

  • The structure of titanium-oxide clusters significantly impacts their catalytic performance.
  • Cluster 1's ability to promote PtNP assembly is key to its enhanced hydrogen evolution activity.
  • These findings offer insights into designing advanced catalytic systems for hydrogen production.
