Porous organic–inorganic hybrid materials for catalysis, energy and environmental applications

Abstract

Introduction of organic functionalities into the porous inorganic materials make the resulting hybrid porous framework not only more flexible and hydrophobic, but also provide additional scope for further functionalization, which...

Nanostructured silicate catalysts for environmentally benign Strecker-type reactions:status quoandquo vadis

“…The latter represents a highly useful and increasingly popular method suitable for organic processes based on multicomponent reactions, and it is believed that the combination of nanocatalysis and these innovative inputs and techniques will enrich and increase our scientific knowledge to another level in the frontier areas. 164 …”

“…The latter represents a highly useful and increasingly popular method suitable for organic processes based on multicomponent reactions, and it is believed that the combination of nanocatalysis and these innovative inputs and techniques will enrich and increase our scientic knowledge to another level in the frontier areas. 164 The selected model reaction to study the nanocatalyzed S-3-CR condensation of benzaldehyde, aniline, and TMSCN is very simple and does not indicate the catalytic activity of the employed nanocatalyst and thus needs some corrections. This model reaction might include ketone components, such as acetophenone or cyclohexanone, and other cyanide sources or cyanation agents, which must be nontoxic components.…”

Chitosan/Silica Nanocomposite Preparation from Shrimp Shell and Its Adsorption Performance for Methylene Blue

“…Organic/inorganic hybrid composite functional materials are one of the hot spots in the research and application of materials science. This kind of material not only has the flexibility and easy modification of organic matter, but also has the rigidity and stability of inorganic matter [18]. Silica is the most representative porous inorganic material, which is widely used in rubber, pesticide, paper making, plastic processing and other industries because of its advantages of high specific surface area, large pore volume, diversified pore structure and many modification methods [19][20][21].…”

Concave octopus-like PtCu nanoframe mediated photo-electro Fenton catalysis for fast organic dyestuff elimination

“…3,4 So it is necessary to reinforce efficient strategies for dyestuff wastewater treatment. 5,6 Recently, numbers of physicochemical formulae have been advanced to adsorb/degrade harmful dyes from colored effluents. The operating methods include physisorption, barrier separation, occulation, coprecipitation, reverse osmosis, chemical oxidation, biodegradation, etc.…”
