Single iron atoms embedded in graphene can catalyse the conversion of methane into methanol at room temperature. Dependent upon the flow of gas from the well, a reactor vessel will be built and housed in a building heated by the raw gas to a temperature of seventy degrees Fahrenheit. This catalyst is carried on a bed of zeolite which will remove nitrogen and nitrogen compounds in adsorption process, as well as some sulphur and a good percentage of carbon dioxide. Iron—nitrogen—carbon (Fe—N—C) acts as the most satisfactory alternatives to platinum for the oxygen reduction reaction (ORR).

Disclosed is a multi-component bismuth molybdate catalyst for production of butadiene which comprises bismuth, molybdenum and at least one metal having a monovalent, divalent or trivalent cation, and further comprises cesium and potassium and thus has advantages of improving conversion ratio, yield and selectivity of butadiene and of providing stability of process operation.

The invention aims to provide a copper mesh coated with manganese molybdate and application thereof in the separation of oil-water emulsion and degradation of organic pollutants in water. A large amount of nano-scale manganese molybdates are grown on the surface of a copper mesh through a two-step hydrothermal method. Thereby, a multifunctional composite material is prepared, which can effectively separate oil-water emulsion and degrade organic pollutants in water. The copper mesh has good recyclability. Most of all, the product is suitable for industrial production to achieve the purpose of treating water pollution.
