Abstract: Disclosed is a method for treating phenol wastewater. The method includes the following step: adding a hydrophobic phthalocyanine as a catalyst, and H2O2 as an oxidant into the phenol wastewater. The hydrophobic phthalocyanine is obtained by decorating a hydrophobic group on a bacterial cellulose-metal phthalocyanine with a silane coupling agent; the bacterial cellulose-metal phthalocyanine is obtained by mixing a metal phthalocyanine into a bacterial cellulose medium, biologically culturing with an acetic acid bacterium, and then heating and reducing the mixture; and the metal phthalocyanine is nitro-sulfonic metal phthalocyanine.

Abstract: A method of synthesizing a doped carbonaceous material includes mixing a carbon precursor material with at least one dopant to form a homogeneous/heterogeneous mixture; and subjecting the mixture to pyrolysis in an inert atmosphere to obtain the doped carbonaceous material. A method of purifying water includes providing an amount of the doped carbonaceous material in the water as a photocatalyst; and illuminating the water containing the doped carbonaceous material with visible light such that under visible light illumination, the doped carbonaceous material generates excitons (electron-hole pairs) and has high electron affinity, which react with oxygen and water adsorbed on its surface forming reactive oxygen species (ROS), such as hydroxyl radicals and superoxide radicals, singlet oxygen, hydrogen peroxide, that, in turn, decompose pollutants and micropollutants.

Abstract: The method relates to the field of asymmetric allylic amination and comprises preparing a chiral N-substituted allylic amine compound from the corresponding allylic substrates and substituted hydroxylamines, in the presence of a catalyst, said catalyst comprising copper compounds and a chiral ligand. Examples of chiral amine compounds which can be made using the method include Vigabatrin, Ezetimibe Terbinafine, Naftifine 3-methylmorphine, Sertraline, Cinacalcet, Mefloquine hydrochloride, and Rivastigmine. There are over 20,000 known bioactive molecules with chiral N-substituted allylic amine substructure. The method may also be used to produce non-natural chiral β-aminoacid esters, a sub-class of chiral N-substituted allylic amine compounds. Examples of β-aminoacid ester which can be produced by the disclosed method, include, but are not limited to, N-(2-methylpent-1-en-3-yl)benzenamine and Ethyl 2-methylene-3-(phenylamino)butanoate. Further, the products of the method described herein can be used to produce chiral heterocycles and bioactive molecules or materials. A novel chiral copper-ligand nitrosoarene complex is also set forth.
