Problems solved by technology

[0004] In the technologies that have been reported so far, the simultaneous construction of heterojunction and metal-modified ternary photocatalytic composite materials requires a two-step or multi-step method, which is complex and costly.
However, the one-step synthesis of non-precious metal-modified heterostructure ternary composite photocatalytic materials has not yet been realized.

Embodiment 1

[0015] Weigh a certain mass of Bi(NO 3 ) 3 ·5H 2 O (1.4552 g) in 60 mL EG was stirred under a magnetic stirrer for 10 min, then 0.2236 g KCl was added, and stirring was continued for 30 min at room temperature. Then add 0.0242 g Na with stirring 2 MoO 4 2H 2 O, after 30 min of reaction, the reaction solution was transferred to a high-pressure reactor, placed in a homogeneous reactor, and heated to 180°C for 12 h. Then naturally cooled to room temperature, the obtained product was suction filtered, washed with water and ethanol three times, and placed in a drying oven at 60 °C for 12 h. After taking out and pulverizing, the synthetic ternary composite photocatalytic material can be obtained.

Embodiment 2

[0017] Weigh a certain mass of Bi(NO 3 ) 3 ·5H 2 O (1.4552 g) in 60 mL EG was stirred under a magnetic stirrer for 10 min, then 0.0242 g KCl was added, and stirring was continued for 30 min at room temperature. Then add 0.0726 g Na with stirring 2 MoO 4 2H 2 O, after 30 min of reaction, the reaction solution was transferred to a high-pressure reactor, placed in a homogeneous reactor, and heated to 180°C for 12 h. Then naturally cooled to room temperature, the obtained product was suction filtered, washed with water and ethanol three times, and placed in a drying oven at 60 °C for 12 h. After taking out and pulverizing, the synthetic ternary composite photocatalytic material can be obtained.

Embodiment 3

Abstract

The invention provides a non-noble metal modified heterostructure ternary composite photocatalytic material synthesized by a simple one-step hydrothermal method and a manufacturing method thereof. Thesynthesis steps can be simplified, the production cost can be lowered, and at the same time the dye degradation performance of a catalytic material can be improved, and the catalytic material is named as BiOCl / Bi2MoO6 / Bi. Compared with the prior art, the method provided by the invention realizes a new way for preparation of the metal modified heterostructure ternary photocatalytic material by one-step hydrothermal method, simplifies the synthesis steps, and lowers the production cost.

Description

technical field [0001] The invention relates to the technical field of photocatalytic materials, in particular to a ternary composite photocatalytic material synthesized by a one-step hydrothermal method. Background technique [0002] At present, the problem of environmental pollution caused by organic pollutants has become a major problem facing the sustainable development of human beings, and has been paid more and more attention by countries all over the world. Photocatalytic technology has high catalytic activity and stability, low price, and environmental friendliness, and has great potential in the field of environmental pollution control. The use of photocatalytic technology can not only treat various organic pollutants, but also has a good effect of sterilizing and inhibiting virus activity, and has no harm to the human body and organisms. Practical significance. Therefore, photocatalytic technology has broad application prospects. [0003] The current research re...
