Platinum (Pt) is a star catalyst that is now widely used in electrode reactions. Very recently, growing experimental evidences have shown that injection of electrons to the Pt catalyst could improve the surface catalytic reactivity to reactant (e.g. the CH 3 OH). However, the underneath ...
A‘catalyst’ is a substance that accelerates a chemical reaction, and within a catalytic converter, there are two types of catalyst. The first is a reduction catalyst which uses platinum and rhodium within the honeycomb to reduce NOx emissions. NOx is produced by nitrogen oxide and nitrogen dio...
Platinum has a high melting point and temperature stability, is highly corrosion oxidation resistant, and it is a good oxidation catalyst. Platinum is biologically compatible and has many significant applications in medicine. Palladium (Pd): Palladium is also used to make jewelry although it’s not...
Why is AgNO_3 stored in an amber bottle? How is nitric acid prepared industrially? Why is a liquid ammonia bottle cooled before opening it? Explain why platinum metal will dissolve in aqua regia (a mixture of hydrochloric and nitric acids) but not in either concentrated nitric or concentrated...
There are certain chemical catalysts, like platinum, that can break hydrogen atoms apart into their constituent protons and electrons. And there are also substances called electrolytes that only let protons pass through them while blocking electrons. So if we combine a catalyst with an electrolyte, ...
While elemental silver is not the most noble metal, and it cannot compete with gold or platinum, yet its dication seemed to be apart from those of all other transition metals. Later, I have learned that quantum chemists have already been able to understand why Ag2+ is special, and where...
Nonetheless, the lustrous hue of silver is unmistakable and recognized all over the world. It is a fairly dense metal, but less so than its cousins palladium, gold, and platinum (in order of density). Aside from being malleable, silver has a middle-of-the-pack melting point compared to ...
In this context, I would like to note that the present article does not aim to provide an answer to the question ‘what is a better OER catalyst than scarce RuO2 or IrO2’, but rather to investigate on a fundamental level ‘what is the correct reference state for material screening by ...

Why is dilute nitric acid not used in the manufacture of hydrogen sulfide instead of dilute sulfuric acid? Oxidizing Agents: Chemical reagents with the ability to cause oxidation of certain substances are known as oxidizing agents. In the process of oxidizing (...
