Abstract: A composition of a photocatalyst, a method of manufacturing the photocatalyst, and a method of chemically reducing carbon dioxide to carbon monoxide using the photocatalyst under visible-light irradiation is provided. The photocatalyst comprises a transition metal ion and graphitic carbon nitride and includes single metal sites on carbon nitride. Under visible light, the metal sites that are coordinated to nitrogen atoms get activated, without the use of additional ligands, to catalyze the reduction of carbon dioxide to selectively produce carbon monoxide. The photocatalytic reduction of carbon dioxide to carbon monoxide is highly efficient, resulting a turnover number of more than 800 for carbon monoxide production in 2 hours. The composition is useful in converting carbon dioxide into useful chemicals and carbon-based fuels. A functional model of molecular catalysts for efficient carbon dioxide reduction is also present.

Abstract: A method of aerobic depolymerization of fiber-reinforced polymer (FRP) composites using sustainable reagents and conditions. A cured matrix is digested into soluble monomers and oligomers by catalytic aerobic oxidation. Carbon fibers are removed for re-use, then the remaining material is treated and valuable monomers are isolated. The isolated monomers can be converted back into resin precursors for re-use. The method solves the problem created because the typically irreversible cure reaction impedes recycling and re-use of FRP composites.

Abstract: Systems and methods for processing a plastic are disclosed. The system includes a feeding device in fluid communication with a cracking unit. A feed stream comprising a plastic is depolymerized in the feeding device at a depolymerization temperature to produce a hydrocarbonaceous wax stream. The hydrocarbonaceous wax stream is then cracked in the cracking unit. The cracking is conducted at a cracking temperature that is lower than, or the same as the depolymerization temperature.

Abstract: Catalyst preforming rates during hydroformylation may decrease in the presence of carbonates. Carbonate mitigation methods may comprise treating a hydroformylation reaction product with an aqueous carboxylic acid under oxidizing conditions to form a deactivated catalyst aqueous solution having a pH of about 4 or less, reducing the hydroformylation reaction product to form a reduced reaction product, conveying a gas stream through the reduced reaction product to strip carbon dioxide therefrom, contacting caustic aqueous solution with the stripped reduced reaction product to form partially spent caustic aqueous solution, combining at least a portion of the partially spent caustic aqueous solution with the deactivated catalyst aqueous solution to form a combined aqueous mixture sufficiently acidic to decompose carbonate, and extracting a Group 9 transition metal carboxylate from the combined aqueous mixture into an organic phase.
