Utilized a concurrent template strategy involving mesoporous platinum or palladium combined with Korea Advanced Institute of Science and Technology-6 (KIT-6) (meso-Pt/KIT-6 or meso-Pd/KIT-6).
Second precursors (metals, metalloids, or non-metals like boron/phosphorus) were introduced under reducing conditions to form intermetallic compounds.
The silica scaffold (KIT-6) was removed using NaOH or HF to yield the final mesoporous structure.

Main Results:

Successfully synthesized ordered mesoporous intermetallic nanomaterials with tunable properties.
Demonstrated the efficacy of the concurrent template strategy for controlled fabrication.
Validated the materials' performance in catalytic applications such as semi-hydrogenation, reduction reactions, and hydrogen evolution.

Conclusions:

The described protocol offers a general and effective approach for preparing ordered mesoporous intermetallic nanomaterials.
This method allows for precise control over composition, morphology, and phase, crucial for optimizing catalytic functions.
These nanomaterials show significant potential for various catalytic applications.
