The interfacial interaction in supported catalysts is of great significance for heterogeneous catalysis because it can induce charge transfer, regulate electronic structure active sites, influence reactant adsorption behavior, and eventually affect the catalytic performance. It has been theoretically experimentally elucidated well metal/oxide oxide/metal inverse catalysts, but rarely reported carbon-supported due to inertness traditional carbon materials. Using an example a...

For single-atom catalysts (SACs), the catalyst supports are not only anchors for single atoms, but also modulators geometric and electronic structures, which determine their catalytic performance. Selecting an appropriate support to prepare SACs with uniform coordination environments is critical achieving optimal performance clarifying relationship between structure property of SACs. Approaching such a goal still significant challenge. Taking advantage strong d-π interaction Cu atoms...

The determination of catalytically active sites is crucial for understanding the catalytic mechanism and providing guidelines design more efficient catalysts. However, complex structure supported metal nanocatalysts (e.g., support, surface, metal-support interface) still presents a big challenge. In particular, many studies have demonstrated that interfaces could also act as primary in reactions, which well elucidated oxide-supported but rarely reported carbon-supported nanocatalysts. Here,...

Owing to unique alkyne-rich structure, graphdiyne (GDY) has been proven be a superb support for anchoring metal catalysts. Herein we demonstrate new role of GDY as the wettability modifier enhanced hydrogenation catalysis. After loading certain amount nanospheres, silica mesoporous channels become superaerophilic, which allows gaseous H2 directly stored inside, thus significantly increasing concentration around palladium nanoparticles (NPs). At same time, nanospheres also alter electronic...

Fully exposed cluster catalysts (FECCs) can not only provide the catalytic sites with multiple metal atoms as in nanoparticles (NPs) but also maintain a full atomic utilization efficiency single-atom (SACs), making them bridge linking SACs and NPs. Due to these particular characteristics, FECCs have been widely studied exhibited enhanced performance dehydrogenation oxidation reactions. However, their application hydrogenation was rarely reported, reaction mechanism has yet be understood....
