A method of producing a catalytic carbon fiber may include: oxidizing a virgin carbon fiber to produce an oxidized carbon fiber; reacting the oxidized carbon fiber with a polyamine compound to produce an amine modified carbon fiber; and reacting the amine modified carbon fiber with an organometallic macrocycle to produce the catalytic carbon fiber.

The present disclosure relates to aerogels based on transition metal complexes, preparation thereof and there use as highly active atomically dispersed oxygen-reduction catalyst with ultra-high catalytic site density and metal content.

A transition metal-based heterogeneous carbonylation reaction catalyst has an excellent catalytic activity and selectivity in the carbonylation reaction and is easily separated from a product, by crosslinking polymerizing a transition metal-based homogeneous catalyst unit through a Friedel-Craft reaction. The catalyst may be used in a method for preparing lactone. The transition metal-based heterogeneous carbonylation reaction catalyst allows to produce lactone or succinic anhydride with an epoxide compound while showing a high selectivity, and can be applied in industrial very usefully due to easy separation from the product and thus reusing thereof.

he invention discloses a porphyrin-based metal coordination conjugated polymer, a preparation method therefor, and an application thereof in photocatalytic degradation of organic pollutants. The catalyst of the present invention has an 18π-conjugated skeleton, a nearly planar macrocyclic molecule, a stable rigid structure and a very stable highly conjugated system, so that the catalyst has excellent photoelectric conversion efficiency, a wide range of absorption spectra, strong redox capacity, and good chemical and thermal stability. A metal coordinated porphyrin acts as active center, a large number of derivatives can be derived, and the method has emerged as a promising alternative for the photocatalytic degradation of environmental pollutants and the like.

The composition and the article of manufacture include a silica particle and light upconversion molecules incorporated into the silica particle. The method includes obtaining sidechain-modified light upconversion molecules, and incorporating the sidechain-modified light upconversion molecules into a silica particle to form a light upconversion particle.

Methods, kits, cartridges, and compounds related to generating chlorine dioxide by exposing ClO.sub.2.sup.− to at least one of an iron porphyrin catalyst or an iron porphyrazine catalyst are described.

A process for use of composite catalysts for oxidation of amines during synthesis of energetic compounds. This method overcomes the safety concerns associated with dangerous reaction conditions for these energetic materials. The process requires exposing phthalocyanine conjugated to an inorganic substrate to the precursor reactant and activating the composite material to light and oxygen to covert amine groups into oxidized nitrogen species.

The present disclosure provides novel methods of making aluminum complexes with utility for promoting epoxide carbonylation reactions. Methods include reacting neutral metal carbonyl compounds with alkylaluminum complexes.

The invention provides novel manganese catalysts such as [Mn(.sup.tBuPc)], which are general for the amination of all types of C(sp.sup.3)-H bonds (aliphatic, allylic, propargylic, benzylic, ethereal), including strong 1.sup.o aliphatic C—H bonds, while achieving excellent chemoselectivity, stereospecificity, and high functional group tolerance. We demonstrate the late-stage diversification of bioactive complex molecules that encompass the range of C(sp.sup.3)-H bond types, such as selective 1.sup.o C—H aminations of betulinic acid and pleuromutilin derivatives. The catalysts' unprecedented balance of reactivity and selectivity is in part attributed to its mechanism of C—H amination that lies between stepwise and concerted.
