Unraveling the Importance of Surface Hydrogen Diffusion in Photocatalysis by Isotope Probing.

Harnessing solar energy for hydrogen generation has motivated extensive efforts to optimize photocatalysts, yet reported efficiencies remain inadequate due to insufficient mechanistic understanding. Using a well-defined Pt/TiO2(110) photocatalyst, time-resolved mass spectrometry, and isotope probing, we show that surfa...

Room-Temperature Adsorption on Magnetite Induces Spontaneous Fragmentation of Early Transition-Metal Size-Selected Nanoclusters

The stability of supported metal nanoclusters, namely, their ability to preserve structure, composition, and catalytic activity over time, is a fundamental prerequisite for catalyst durability, resistance to deactivation, and long-term performance under operating conditions. Despite their often-exceptional intrinsic...
