Embodiment 1

[0028] A method for preparing a nitrogen-sulfur co-doped ordered mesoporous carbon material, comprising the following steps:

[0029] First, weigh 0.5 g of methylene blue, 30 μL of concentrated sulfuric acid with a concentration of 98% and 5 mL of water, first add the weighed methylene blue into the water to make an aqueous solution of methylene blue, then add the aqueous solution of methylene blue while stirring the concentrated sulfuric acid, mix well and prepare into a mixture;

[0030] Secondly, inject the mixed liquid into 0.5g SBA template by nano casting method;

[0031] Again, the SBA material injected with the mixed solution was preheated in multiple stages, first heated in an oven at 100°C for 5 hours, and then heated in an oven at 150°C for 8 hours;

[0032] Then, the preheated material was heated at 900° C. for 3 h under a nitrogen atmosphere;

[0033] Finally, remove the SBA-15 template in the material after cooling, soak in 30% HF solution for 24 hours to remov...

Abstract

The invention discloses a preparation method of a nitrogen and sulfur co-doped ordered mesoporous carbon material, an electrode plate and application. Uniform doping of a mesoporous carbon material can be effectively realized by selecting a single carbon source as a nitrogen and sulfur co-doping agent, and thus the phenomenon of non-uniform doping of heteroatoms caused by multiple carbon sources is avoided. Compared with a carbon nano tube and graphene, the prepared nitrogen and sulfur co-doped ordered mesoporous carbon material shows higher electrocatalytic activity. An electrode plate prepared by coating of the nitrogen and sulfur co-doped ordered mesoporous carbon material can effectively detect amino triazole in a river water sample, the detection limit is relatively low, and a satisfactory recovery rate is obtained.

Description

technical field [0001] The invention relates to the technical field of mesoporous materials, in particular to a method for preparing nitrogen-sulfur co-doped ordered mesoporous materials, and an electrode sheet made of the ordered mesoporous material and the electrode sheet used to detect amino groups in water bodies. Triazole application. Background technique [0002] At present, the methods that can realize the quantitative and accurate detection of aminotriazole at home and abroad mainly include liquid chromatography, gas chromatography and capillary electrophoresis. However, among these methods, some have disadvantages such as expensive instruments, high operating costs, and not easy to carry, and some require complicated pretreatment. Therefore, it is not easy to realize online, real-time and continuous biomolecular detection. Electrochemical methods (ie, electrochemical sensors) are easy to automate and portable, and are expected to realize online, real-time, and con...
