Problems solved by technology

Activated carbon fiber is a new type of microporous activated carbon containing disordered nano-graphite. It is a relatively modern and highly microporous carbon material. It has many important advantages over traditional powder or granular forms. Activated carbon fiber is used as a carrier Combined with a catalyst, it shows better catalytic performance and regeneration ability. There is no report on the composite of activated carbon fiber and nickel phosphide.

Embodiment 1

[0064] The cocoons were boiled in boiling water at 100 °C for 30 min, then cooled in cold water and manually drawn, and the obtained silk was dried in an oven at 80 °C to obtain mulberry silk with sericin removed. Formulated with a mass fraction of 10% (NH 4 ) 2 HPO 4 solution, according to 1 g mulberry silk with 30 ml (NH 4) 2 HPO 4 The proportion of the solution was dipped, the dipping time was 12 h, and then it was dried and dried in an oven at 80 °C. The mulberry silk was pre-oxidized in a muffle furnace at 250 °C for 1 h to obtain pre-oxidized silk. Pre-oxygen wire in vacuum tube furnace N 2 Under the protection, it was heated to 600 °C at a heating rate of 5 °C / min, kept for 60 min, and then carbonized. After the temperature dropped to room temperature, the nitrogen flow was cut off, and the carbonized material was taken out. Put the prepared carbon material in a vacuum tube furnace N 2 Program temperature roasting under protection: heating to 900 °C at a heatin...

Abstract

The invention discloses an active carbon fiber and a graded porous Ni-Ni3P / active carbon fiber composite material as well as preparation and application of the two. The active carbon fiber contains three elements including C, O and P and is in an amorphous state and a turbostratic graphitic structure; the shape of the active carbon is similar to that of a mulberry silk fiber; and the active carbon fiber is mainly formed by meso-pores and a lot of oxygen-containing functional groups exist on the surface of the active carbon fiber. Ni and Ni3P are loaded on the active carbon fiber through an immersion sintering method to obtain the composite material. According to the invention, mulberry silk is taken as a template, and the prepared active carbon fiber and composite material are good in performance and simple to prepare, have the effect of better degrading organic dyes under light illumination and microwaves, and have good meanings to organic wastewater treatment in practical production.

Description

technical field [0001] The invention relates to an activated carbon fiber and a hierarchically porous Ni-Ni fiber with the activated carbon fiber as a carrier 3 P / activated carbon fiber composites, and their preparation methods and applications. Background technique [0002] Activated carbon fiber (ACF), also known as fibrous activated carbon, is an ideal high-efficiency active adsorption material; it is developed on the basis of the combination of carbon fiber technology and activated carbon technology, and is the " The third generation of activated carbon". Compared with traditional AC, it has a larger specific surface area, faster adsorption and desorption speed and higher adsorption efficiency due to its unique pore structure and morphology. It is an adsorbent with stronger adsorption capacity and has a broad range of Prospects. Activated carbon fiber has not only become a replacement product of traditional activated carbon, but more importantly, it has opened up area...
