Particularly, using reducible oxides as support provides a favorable metal-support interaction leading to a notable increase in the catalytic activity and stability of plati-num(0) nanoparticles. (iv) The utilization efficiency of the precious platinum nanocatalysts can be significantly enhanced by ...
Whilst some is used in jewellery, the majority of the palladium and platinum produced today is snapped up by automobile manufacturers, to produce catalytic converters.A metal must have all three aspects to be precious, and even then some are more precious than others. You can get a good ...
The auto industry uses platinum for catalytic converters, which can help reduce the toxicity of gases and pollutants in the exhaust that an internal combustion engine creates. Platinum and other platinum-grade metals in catalytic converters have led to a secondary market for scrap converters, which ...

minerals out of an asteroid, then bring the valuable metals back to Earth, leaving the rest. The company is targeting M-type, or metallic, asteroids for platinum group metals (PGMs), which are used in everything from jewelry to catalytic converters that filter car exhaust to cancer-fighting ...
(NMs) face challenges due to, among others, the numerous existing nanoforms, discordant data and conflicting results found in the literature, and specific challenges in the application of strategies such as grouping and read-across, emphasizing the need for New Approach Methodologies (NAMs) to ...
Also, the DMFC requires a relatively large amount of platinum to act as a catalyst, which makes these fuel cells expensive. Reversible Fuel Cells A reversible fuel cell combines two methods of energy production, uniting one of the previous fuel cell types with a solar or a wind generator. ...
3.5. Platinum 3.5.1. Cisplatin NRF2, as stated earlier, is the key factor in the process of ferroptosis. In colorectal cancer cells, oxaliplatin treatment can suppress NRF2 signalling and cause ferroptosis, which may be closely related to the generation of ROS[140]. As mentioned above, NRF2 ...
While gold and silver are commonly used for jewelry, there are also industrial applications for precious metals. Platinum, palladium and rhodium are used in catalytic converters; ruthenium and rhenium are used in electronics and scientific instruments; and iridium is used in spark plugs.4 ...
