Embodiment Construction

[0019] The present invention will be further described below in conjunction with drawings and embodiments.

[0020] 1. Preparation of novel nickel-molybdenum alloy nanoparticles

[0021] (1) MoNiO X / Preparation of CNTs:

[0022] Mix 20mg of carbon tubes with 60ml of ethylene glycol, and disperse them evenly after ultrasonic treatment for 1h. Add it to a 100ml round bottom flask, then add 150mg of Mo(CO) 6 and 100mg of Ni(OAc) 2 , under the condition of 190°C, react at a stirring speed of 1500r / min for 3h, cool to room temperature after the reaction, and wash with ultrapure water several times to obtain the product MoNiO X / CNT.

[0023] (2) Preparation of MoNi / CNT nanostructures:

[0024] 30mg of MoNiO X / CNT tiled in the magnetic boat, put the magnetic boat into the tube furnace for heating, after the air in the tube furnace is exhausted, 2 / Ar atmosphere was heated to 500 ° C and kept for 30 min to obtain the product MoNi / CNT.

[0025] According to the ratio of ra...

Abstract

The invention discloses a preparation method of novel nickel-molybdenum alloy nano-particles and a method for treating wastewater by using the novel nickel-molybdenum alloy nano-particles. The preparation method comprises the following steps: (1) preparing MoNiOx / CNT; and (2) preparing a MoNi / CNT nano-structure. The nickel-molybdenum alloy nano-particles prepared through the method have high electro-catalytic performance, after Mo-Ni alloy is formed, Ni and Mo generate a synergistic effect, the oxygen evolution potential is reduced, hydroxyl free radicals are generated, meanwhile, under high-current-density electrolysis, Mo has a dissolution effect, a porous structure can be formed, the real surface area of the electrode is increased, and the electro-catalysis effect of the nickel-molybdenum alloy nano-particles is further improved.

Description

technical field [0001] The invention relates to the technical field of sewage treatment, in particular to a method for preparing novel nickel-molybdenum alloy nanoparticles and a method for treating wastewater. Background technique [0002] With the development of modern industry, the discharge of industrial water and waste water is increasing day by day, and the water bodies of all countries in the world have been polluted to varying degrees, leading to an increasingly serious crisis of water scarcity worldwide. In order to greatly alleviate the shortage of water resources, the research on industrial wastewater treatment technology has been paid more and more attention by people. [0003] Currently, many methods have been developed to treat wastewater, including physical, chemical or biological processes. Although biological treatment is a low-cost technology, due to changes in wastewater properties, high chemical oxygen demand (COD) concentrations, and low biodegradabilit...
