Synthesis of industrial relevant ZSM-5 supported nano-sized metallic cobalt catalyst

Most chemical reaction of industrial relevance are catalysed by different metals in their metallic state. However, after catalyst synthesis which involves calcination to adequately anchor those active metals unto the catalyst supports, the metals were oxidized, thus

Creating artificial enzymes from small building blocks

Artificial enzymes were first described several decades ago and have become an ambition for bionanomaterial sciences. Artificial enzymes are small fabricated molecules that possess an active centre, which binds to a substrate and catalyses a chemical reaction.

Micelle catalyzed 4-nitrophenol reduction

In aqueous solution, molecules with both polar head group and non polar tail (amphiphilic molecules) aggregate i.e., micelles. They absorb/uptake both polar and non polar molecules from solution as a universal host. Thus the horizon of catalysis, detergency,

Water oxidation by a biomolecule (amavadin) without light contribution

Amavadin is a metallobiomolecule without amino acids that occurs with a significant concentration in a few closely related Amanita fungi, such as A. muscaria. It is a [V(S,S-HIDPA)2]2- complex anion (see Figure 1, assigned with A) with

C-H bond activation by metal carbene

C-H bonds, alongside with C-C bonds, are the most common chemical bonds that constitute organic molecules. C-H bonds are ubiquitous and they are also very stable. The replacement of the hydrogen atom of the C-H bond with

Catalytic carbon-carbon bond formation

A chemical reaction is the transformation of one or more reagents into one or more products that takes place at a characteristic rate depending on the energy needed to activate the process. A catalyst is a substance

Electrochemical oxidation of americium and its role in nuclear waste processing

Nuclear energy is a promising source of renewable energy, however, to facilitate its adoption and avoid nuclear proliferation, solutions to the handling, reprocessing, and disposal of nuclear waste must be addressed. In the United States, commercial reactors

Streamlined construction of a natural product framework

Nature makes biologically active organic molecules bearing complex polycyclic frameworks equipped with functional groups so efficiently from simple starting materials. For example, arylnaphthalide lignan natural products derived from plants, such as diphyllin, justicidin A, taiwanin E, and

Tuning surface/interface of nanocarbon: promoted catalysis

Catalysis is the cornerstone for chemical industries. The development of low-cost sustainable catalysts with high catalytic activity, selectivity, and stability under mild conditions remains at the heart of modern material chemistry, green chemistry, and catalysis fields for
