Values of m are potentially helpful in the characterization of used palladium catalysts.
The palladium particle size can be controlled by addition of AAPTS and plays a significant role in the catalytic performance.
It overcomes the problems that palladium has leached badly and recovery difficultly in conventional homogeneous palladium catalyst field, and have a broad foreground of catalyst applications.
Catalysts and reaction protocol offer combined advantages of high catalytic efficiency under ambient conditions (air and moisture), easy separation and reuse and quantitative recovery of palladium.
The composition of the palladium NPs is different for each catalytic cycle indicating a dynamic process and the formation of different catalytic active species.
The method is applicable for palladium estimation in Ores and catalysts.
It appears that only a small fraction of the palladium surface is active for methane combustion.
The study reveals that apparently distinct palladium catalysts can display similar activities in such transformations, implying formation of a comparable active palladium catalyst phase.
This suggests that the catalytic behavior of palladium is largely preserved in the bimetallic samples.
The high efficiency of the catalytic reaction was affirmed by the good yields of products, easy work-up, absence of palladium leached from the support and smooth recovery of catalyst.
