I am trying to optimise the kinetics of light weight hydrides using different catalysts.
Hello Pawan,
thank you for sharing this very interesting technical qestion with the RG community. Previous studies in this field have shown that the transition metals Ni, Fe, Rh, and Pd have the best possible catalytic activity in this context. For more detailed information please have a look at the following relevant literature reference:
Catalytic Tuning of Sorption Kinetics of Lightweight Hydrides: A Review of the Materials and Mechanism
The full text of the Open Access article is freely available on the internet (please see the attached pdf file).
Good luck with your work!
Thanks, Frank. I really appreciate you for sharing such an informative article.
Dear Pawan Kumar Soni ,
At least, from my perspective, your question is too ambiguous to be answered directly. Depending on the reaction to be carried out, there are metals that work very well, or oxides that have very good activity. Some semiconductors also behave well in general but, as I said before, it will depend on the reaction.
Best,
Fran
Yes. You are right Francisco Manuel Marquez. However, catalysts show better performance in nanoscale. In case of metals, it would be difficult to find nano sized particles easily while it is easier in the case of metal oxide. Metal oxides are so brittle that can be pulverized into very fine particles. So, I was asking for a fair comparison between metal, metal oxide or metal halide. (eg. Fe, Fe304, FeCl3)
The simple logic is if you enhance the surface area the catalytic activity increases. So the nanoparticles can act as a better catalyst when compared to those of bulk material. Between the metal and metal compounds , I don't think any generalization can be made. Each system is unique and it can not be extrapolated to all other reactions.
Dear Pawan Kumar Soni . The catalyst action depends on the surface area and type of catalyst. See the following useful link: https://www.sciencedirect.com/science/article/abs/pii/S0255270115300957

Dear Pawan . The catalyst action depends on the active surface area, reaction time, environmental condition, and the type of catalyst. There a large number of Metallic and intermetallic compounds investigated for superior catalyst activity. So the catalyst action will be depend on the type of reaction and the environmental condition.
