Abstract

The invention discloses a novel catalytic material and its preparation method and application. The preparation method comprises the following steps: (1) placing a conductive substrate in a mixed solution of cobalt salt, nickel salt, ammonium fluoride and urea for solvothermal reaction, A precursor electrode containing Co and Ni elements is obtained; (2) imidazole is calcined under an inert atmosphere to obtain imidazole vapor, and the precursor electrode is placed in imidazole vapor to obtain a CoNi-MOFs electrode; (3) sulfur-doped nitrogen Carbonized carbon powder is dispersed in water to form a suspension, the CoNi-MOFs electrode is soaked in the suspension, and processed by high-energy treatment technology to obtain the new catalytic material. The novel catalytic material of the present invention has excellent hydrogen evolution and oxygen evolution performance, is a dual-functional catalytic material with excellent performance, and can be widely used in many electrocatalytic fields including pollutant degradation and electrocatalytic cracking of water for hydrogen and oxygen production.

Description

technical field [0001] The invention relates to the technical fields of electrolyzed water for hydrogen and oxygen generation, wastewater treatment and electrocatalytic materials, and in particular to a novel catalytic material with dual functions of decomposing water for hydrogen and oxygen generation and degrading pollutants, as well as its preparation method and application. Background technique [0002] Environmental pollution and energy shortage are two important issues facing society today. On the one hand, with the development of the economy, the unreasonable disposal of a large number of terminal wastes has caused serious environmental pollution problems; on the other hand, the current fossil fuels, such as coal, oil and natural gas, are becoming increasingly depleted and cannot Meeting the energy needs of today's society. Therefore, the development of green and clean energy and the control of environmental pollution are major challenges for the sustainable developm...
