The catalytically active sites in MOFs are commonly metal centers, and most reported MOFs are monometallic. Generating multimetallic building units in MOFs has been recently proposed as an effective strategy to regulate their catalytic properties38,39. Exploring multimetallic MOFs for catalytic O3decomposi...

More encouragingly, these graphene-based catalysts show favorable HER activity in a wide range of pH values, in contrast to traditional metallic and nanostructured MoS2 electrocatalysts, which are active under either acidic or basic conditions. To design high-performance electrocatalysts for HER, Jiao ...
Vanadium can be extracted from neutral, acidic or basic solutions by solvent extraction processes [71]. Some of the relevant studies are presented in Table3. Table 3 Effectiveness of different extractants on vanadium extraction Full size table ...
Nanoparticles and microparticles are most likely taken up by endocytosis and deposited in lysosomes. They are dissolved here due to the acidic pH, delivering large amounts of copper ions close to the nucleus [63,66,67]. 2.5. Crystallinity The various conditions including the nature of surfactant...
In strongly acidic conditions, quinolone molecules possessing a basic side nucleus are protonated and appear as cations in the ionic complexes. Interaction with metal ions has some important consequences for the solubility, pharmacokinetics and bioavailability of quinolones, and is also involved in the ...
alumina in pH ranges between 4 and 9 is very low and the material is, therefore, chemically and physically stable in this pH range. However, beyond this pH range, on either the basic or acidic side, alumina becomes soluble in aqueous media and its physical strength and integrity degrades ...
Accompanying this applied focus has been a recognition of the need to engender MOFs with mechanical, thermal and/or chemical stability. Chemical stability in acidic, basic and neutral aqueous solutions is important. Advances over recent years have made it possible to design MOFs that possess ...
Agglomeration of gold and other metal nanoparticles under conventional reaction conditions (for example, high temperature, high pressure, strong acidic or basic conditions) is recognized as one of the major limitations in catalysis.5 Therefore, supported metal nanoparticles were developed to improve the ...
