Abstract: There is a process for preparing polycarbonate. The process has the step of copolymerizing an epoxy compound and carbon dioxide (CO2) in the presence of a catalytic system having at least one catalyst selected from complexes of a transition metal having general formula (I): The aforesaid process allows to obtain polycarbonates having a quantity of carbonate bonds in chain greater than 95% or polycarbonate/polyether copolymers having a quantity of ether bonds in chain ranging from 15% to 90%.

Abstract: A hydroxamic acid-metal hydroxide coordination complex and preparation and application thereof are disclosed. The hydroxamic acid-metal hydroxide coordination complex is formed by a coordination of hydroxamic acid with divalent or higher valent metal ions under an alkaline condition. The hydroxamic acid-metal hydroxide coordination complex has a strong selectivity and a strong collection ability for metal oxide minerals such as tungsten-containing minerals, ilmenite, rutile, cassiterite, and rare earth. The preparation method is simple and low in costs, and is beneficial to industrialized production.

Abstract: An ammonia production method is a method that produces ammonia from nitrogen molecules by donating electrons from a power supply, protons from a proton source, and the nitrogen molecules from means for supplying a nitrogen gas in presence of a complex, a solid catalyst, and a reaction field forming material in a cathode by a production apparatus for performing electrolysis. In the complex, the solid catalyst, and the reaction field forming material, for example, a molybdenum complex expressed by Formula (A1-1) is used as the complex.
A platinum catalyst is used as the solid catalyst, and a rare earth metal-carbon-based binder is used as the reaction field forming material.-

Abstract: A process for preparing a catalyst material, includes the steps of: (a) providing a support material having surface hydroxyl (OH) groups, wherein the support material is ceria (CeO2), zirconia (ZrO2) or a combination of thereof; (b) reacting the support material having surface hydroxyl (OH) groups of step (a) with a precursor containing two transition metal atoms, each chosen independently from the group consisting of: W, Mo, Cr, Ta, Nb, V, Mn; (c) calcining the product obtained in step (b) in order to provide a catalyst material showing dual site surface species containing pairs of transition metal atoms derived from the precursor that are present in oxide form on the support material. Additionally, a catalyst material is obtained by the process set out above, and the catalyst material is used as an ammonia selective catalytic reduction (NH3-SCR) catalyst for nitrogen oxides (NOx) reduction.

Abstract: Molybdenum(0) and coordination complexes are described. Methods for depositing molybdenum-containing films on a substrate are described. The substrate is exposed to a molybdenum precursor and a reactant to form the molybdenum-containing film (e.g., elemental molybdenum, molybdenum oxide, molybdenum carbide, molybdenum silicide, molybdenum disulfide, molybdenum nitride). The exposures can be sequential or simultaneous.
