Problems solved by technology

However, since g-C 3 N 4 The shortcomings of high charge carrier recombination rate, low quantum efficiency, small specific surface area, poor conductivity, and insufficient absorption performance above 460 nm make g-C 3 N 4 There are still obstacles in practical application
To improve g-C 3 N 4 For photocatalytic efficiency, metals such as platinum are often used as co-catalysts to improve the photocatalytic effect. However, platinum is a noble metal, and its high cost limits its application. Noble metal co-catalysts are promising and meaningful

Embodiment

[0023] Example: including Ni 3 C / 2D g-C 3 N 4 Nano-heterojunction, the mass ratio of nickel carbide / carbon nitride is 5:100~25:100; the nickel carbide is a nano-particle, and the carbon nitride is a two-dimensional nano-sheet. Wherein, the mass ratio of nickel carbide / carbon nitride is 15:100.

[0024] The preparation of nickel carbide / carbon nitride nanosheet photocatalytic material comprises the following steps:

[0025] S1. Put melamine in a ceramic crucible with a cover, heat up to 550°C in a muffle furnace at a rate of 2°C / min and calcinate for 250min to obtain a yellow substance, grind the yellow substance into powder, and spread 400mg of the yellow powder on the In the uncovered ark, put it into a muffle furnace and heat up to 550°C at a rate of 10°C / min for calcination for 90 minutes to obtain a white powder material that is a two-dimensional carbon nitride nanosheet.

[0026] S2. Put 300 mg of nickel (II) acetate and 10 mL of oleylamine into a three-neck round bot...

Abstract

The invention relates to a photocatalytic material, particularly to a metallic nickel carbide / carbon nitride nanosheet photocatalytic material, a preparation method and application thereof, and belongs to the technical field of nano materials and hydrogen production by water photolysis. In a nitrogen atmosphere, nickel acetylacetonate is subjected to low-temperature pyrolysis in olefinic amine toprepare high-quality Ni3C nanoparticles, and on the basis, a novel Ni3C / 2D g-C3N4 nano heterojunction is successfully synthesized by adopting a simple two-step method, wherein the hydrogen productionperformance is obviously improved compared with the hydrogen production activity of single two-dimensional carbon nitride.

Description
