Title:
PREPARATION METHOD AND APPLICATION OF MONOLITHIC COBALT-DOPED NICKEL-MOLYBDENUM NANOWIRE CATALYST
Document Type and Number:
WIPO Patent Application WO/2022/227367
Kind Code:
A1
Abstract:
Disclosed in the present application a preparation method and application of a monolithic cobalt-doped nickel-molybdenum nanowire catalyst. The catalyst comprises a carrier and an active substance grown in situ on the carrier. The active material comprises cobalt, nickel, and molybdenum. The preparation method comprises: 1. generating a precursor on a carrier by means of a hydrothermal reaction; and 2. performing in-situ electrochemical activation on the precursor to obtain a monolithic cobalt-doped nickel-molybdenum nanowire catalyst. The monolithic cobalt-doped nickel-molybdenum nanowire catalyst provided by the present application is high in stability and long in service life, has rich pore structure and large-length-diameter ratio nanowire morphology, improves reaction mass transfer and load transfer rate. Compared with a nano-powder catalyst, the catalyst of the present application is easily separated from a product after reaction, and can be reused multiple times. The catalyst can be applied to the fields of chemical engineering, environmental protection, biomass conversion and the like, and is particularly suitable for electrocatalytic reaction of large-current biomass.
