Synthetic method of load type molybdenum carbide catalyst

Abstract

The invention relates to a synthetic method of a load type molybdenum carbide catalyst, which belongs to the field of catalytic materials and comprises the steps of: dispersing organic-inorganic mixed molybdenum oxide-polyaniline used as precursors in H2O/EtO; drying after mixing with carriers, such as carbon nanotubes and the like; and then roasting at an inert atmosphere to obtain the load typemolybdenum carbide catalyst. In the load process, other metal salts can also be added to modify the molybdenum carbide catalyst to obtain a metal modified load type molybdenum carbide catalyst. The molybdenum carbide catalyst prepared by the invention has the advantages of large external surface area, less surface carbon deposition, abundant catalytic performance of precious metal and the like, and can be used for conveniently modifying the catalyst. The loading molybdenum carbide catalyst has important application in various catalytic reactions.

Description

technical field [0001] The invention belongs to the field of catalytic materials, and in particular relates to a synthesis method of a supported molybdenum carbide catalyst. Background technique [0002] Since carbide was introduced into the field of catalysis by the famous American catalyzer Boudart in 1973, carbide represented by tungsten and molybdenum has become a It is one of the most promising catalytic materials in the past one or two decades. Especially in recent years, with the rapid rise of oil prices, the calls for efficient and green utilization of energy and resources have been increasing, and the development of carbide catalytic performance and new catalytic reactions has further attracted people's attention. In addition, because the raw materials for carbide synthesis are relatively cheap, it is also of great significance in saving precious metal resources and reducing the cost of catalytic reactions. At present, the reactions involved in molybdenum carbide ...

Problems solved by technology

However, these methods are limited by their own disadvantages, such as the use of H at high temperature 2 As well as the operational hazards brought by Na metal, the surface area carbon caused by interfacial reactions, and the difficulty in dispersing carbide particles, they have relatively large deficiencies in practical applications, especially in the mass production of catalysts.

However, there are no reports of this
