Abstract

ABSTRACT In this thesis, TiO2 was first prepared by one-step hydrothermal method, then HF was used as an F source, and TiO2 was treated by a DBD plasma reactor under an N2 atmosphere, and the F/N co-modification of TiO2 was realized. In the visible light catalytic degradation experiment of 60 mg/L methylene blue, the overall catalytic performance of the catalyst treated with DBD plasma for 80 min was the best, with a degradation rate of 91% in 10 min and 96% in 60 min. Result Indication: DBD plasma treatment did not affect the phase structure and morphology of TiO2, but formed surface defects and surface adsorption on its surface, and successfully doped two non-metallic elements, F and N, thereby enhancing the photocatalytic degradation activity.

DBD等离子体F/N共掺杂改性TiO2的制备及其光催化性能

本论文首先采用一步水热法制备TiO2，然后以HF为F源，在N2气氛下用DBD等离子体反应器处理TiO2，实现了TiO2的F/N共改性。在60 mg/L亚甲基蓝可见光催化降解实验中，DBD等离子体处理80 min的催化剂整体催化性能最好，10 min降解率为91%，60 min降解率为96%。结果提示:DBD等离子体处理不影响TiO2的相结构和形貌，但在其表面形成表面缺陷和表面吸附，并成功掺杂F和N两种非金属元素，从而增强了光催化降解活性。图形抽象

期刊介绍： Phase Transitions is the only journal devoted exclusively to this important subject. It provides a focus for papers on most aspects of phase transitions in condensed matter. Although emphasis is placed primarily on experimental work, theoretical papers are welcome if they have some bearing on experimental results. The areas of interest include: -structural phase transitions (ferroelectric, ferroelastic, multiferroic, order-disorder, Jahn-Teller, etc.) under a range of external parameters (temperature, pressure, strain, electric/magnetic fields, etc.) -geophysical phase transitions -metal-insulator phase transitions -superconducting and superfluid transitions -magnetic phase transitions -critical phenomena and physical properties at phase transitions -liquid crystals -technological applications of phase transitions -quantum phase transitions Phase Transitions publishes both research papers and invited articles devoted to special topics. Major review papers are particularly welcome. A further emphasis of the journal is the publication of a selected number of small workshops, which are at the forefront of their field.
