Abstract: A single-atom catalyst for use in a water splitting process includes at least one support material and at least one metal catalyst deposited on the surface of the at least one support material. The at least one support material is made of tungsten carbide obtained from a tungstate-metal-aryl compound precursor, and the at least one metal catalyst is selected from a group including Fe, Ni, Mn, Co, Cu, Zn, V, Ru, Ir, Ca, Pd, Pt or combinations thereof.

Abstract: A method for obtaining metal oxides supported on mesoporous silica particles includes a) providing a solution of at least one metal salt, b) providing a solution of at least one template forming agent of the general formula (I) Y3Si(CH2)n—X (I), wherein X is a complexing functional group; Y is —OH or a hydrolysable moiety selected from the group containing halogen, alkoxy, aryloxy, acyloxy, c) mixing the metal salt solution and the complex forming agent solution to obtain a metal precursor; d) adding at least one solution containing at least one pore structure directing agent to the metal precursor to obtain a metal precursor template mixture; e) adding at least one alkali silicate solution to the metal precursor template mixture at room temperature to obtain a silica-supported metal complex; and f) calcination of the silica-supported metal complex under air to obtain the supported metal oxide mesoporous silica particles.

Abstract: Platinum(II) complexes and the use of these complexes for oxidation of methane to methyl sulfate are disclosed, the catalyst having, as ligands, a network based on aromatic N-heterocycles which has at least 2 coordinative nitrogen atoms per platinum atom, and the complex anion is selected from a halide, hydrogensulfate, hydrogensulfite, sulfate, sulfite, methylsulfate, methanol, water, hydroxide, carbon monoxide, hydrogencarbonate and carbonate. The catalyst enables a selective low-temperature oxidation of methane to methyl sulfate or methanol. The catalysts not only exhibit high activity, but can also be removed easily from the reaction mixture and reused over several runs without significant loss of activity.

Abstract: The present invention relates to a method of preparing porous solids, which method comprises polymerizing, in a salt melt or a eutectic mixture of salt melt containing at least one Lewis acidic salt, cyano monomers having at least one or at least two cyano groups in their molecule, wherein the at least one or at least two cyano groups are bonded to a rigid linking group in the cyano monomer, as well as to the porous solids obtainable by that method. Owing to their porosity and the associated extremely high specific surface area, the porous solids are useful as sorbents, filtering and insulating materials, as well as catalyst carriers.
