Sentence examples for diffusion of catalyst from inspiring English sources

For the case without secondary etching, the surface diffusion of catalyst particles was limited by the layer of redeposited material at the ridges.

This happens because of the difference in the diffusion rate of catalyst nanoparticles into each other in different temperature ranges.

To prevent diffusion of the catalyst, hydrogen chloride is added in the gas flow [36].

Low yields can be attributed to the diffusion of reactant, catalyst, and product through the diaphragm of the divided cell.

This lifetime enhancement occurs because the refractory metal inhibits the surface diffusion of the catalyst metals, slowing the Ostwald ripening of the catalytic particles and allowing them to grow CNTs for greater times, resulting in longer CNTs.

The mechanical compression forces applied to the pretreated material could cause deterioration of the wood matrix and thus influence the extent of diffusion of the catalyst during impregnation, as well as the heat transfer to the woody material [ 23, 26].

In order to enhance the HER activity, the structure of carbon-based materials needs to be carefully engineered to maximize the exposure of active sites, improve the electrical conductivity and shorten the ion diffusion pathway of catalysts.

In addition to boost the reduction the catalyst precursors, the high chemical reactivity of metallic aluminum drives the thermal formation of an oxide layer on the Al surface that suppresses the diffusion and aggregation of catalyst nanoparticles.

To synthesize vertically aligned carbon nanotube (VA-CNT) arrays longer than a millimeter using chemical vapor deposition (CVD), aluminum oxide buffer has to be deposited on supporting substrates to prevent diffusion and aggregation of catalyst nanoparticles.

Due to the fast intrinsic reaction rate of H2 oxidation on the Pt catalyst, the diffusion of H2 in the catalyst layer affected the overall reaction rate to a higher extent when the Pt loading or the overpotential increased.

This is likely because of the diffusion of the copper catalyst incorporated in the growth of the Si nanowires.
