Introduction
The ability of Ru to exist in various states of oxidation is a crucial property which enhances the application of Ruthenium in different sectors.
Ru readily established coordinate complexes which are essential in its application in various fields such as medicine, catalysis, biology, Nano science and photoactive materials.
General Application of Ru
The medical application of Ru involves the diagnostic and treatment aspects of various ailments. Ruthenium and its complexes is usually employed in determination of ferritin, calcitonin and cyclosporine and fatal levels in human body for diagnosis of the disease. In the treatment aspect, Ru is employed in immunosuppressant, anticancer activities and antimicrobial (Sahu et al., 2018).
Application 2
Ruthenium Nanoparticles Decorated Tungsten Oxide as a Bifunctional Catalyst for Electro catalytic and Catalytic Applications
A previous study showed that the physiochemical properties of Ru-WO3 have super electrochemical performances essential for sensitive and selective detection of N2H4 with a desirable wide range of 0.7−709.2 μM and a detection limit and sensitivity of 0.3625 μM and 4.357 μA μM−1 cm−2 , respectively, surpassing other modified electrodes.
In addition, the Ru-WO3 catalysts were found to have good catalytic activities for the oxidation of DPS in presence of water oxidant giving desired sulfoxide yields (Rajkumar et al., 2017).
Application 3
Catalysis with Colloidal Ruthenium Nanoparticles
A recent review showed that ruthenium nanoparticles are essential catalysts in solution for diverse reactions.
The main application in this case includes; oxidation, reduction, Fischer-Tropsch, C-H activation, CO2 transformation, and hydrogen production via amine Borane dehydration or water-spitting reactions (Axet and Philippot, 2020).
Application 4
Nano catalysts depended colometric assay has the ability to detect and provide a novel context for the detection of hydrogen sulfide.
The Ru Nano catalysts depended colometric assay by contrast has the benefit of simple operation, quick responses and increased sensitivity and it is appropriate to attain on site visual analysis of H2S. due to the growth of Nano catalysts, ruthenium NPs as transition metals have high catalytic hydrogenation roles and can be used in minimization of nitro aromatic elements and azo dyes (Zhao, Luo, Zhu, et al., 2017).
Application 5
Metals and semiconductors nanoparticles have a wide application in the fields of catalysis, photography, optics, electronics, optoelectronics, data storage, and biological and chemical sensor.
The Pt. Ru/C catalyst have the best catalytic performance since ruthenium takes long electrochemistry time to dissolve.
it has the ability to keep the highest current density and a low rate of current decay for over one hour in all catalyst (Huang et al., 2005).
Application 6
The Ru based catalysts are the most effective anode catalyst for the methanol oxidation reaction in direct methanol fuel cells (DMFCs).
PtRu alloy Nano crystals have been recognized as being majorly effective electro catalysts for methanol oxidation. Pt.-Ru catalyst portrayed greatest methanol oxidation current and a lower poisoning abilities.
Crystalline RuO2 is an important element to have an efficient methanol oxidation form Pt nanoparticles. Pt-Ru catalyst have the ability to manage the chemical state of Ru to come up with RuO2H instead of Ru metal or basically anhydrous RuO2 due to inefficient proton conduction (Wang et al., 2016)
Conclusion
Ru metal has a wide application in various fields.
The ability of Ru to exist in various states of oxidation is a crucial property which enhances the application of Ruthenium in different sectors.
Additionally Ru readily established coordinate complexes which are essential in its application in various fields such as medicine, catalysis, biology, Nano science and photoactive materials.
