摘要
由于城市化和工业化的快速发展，环境中污染物的增加已成为当今的主要关键问题之一。因此，研究人员开始关注用于降解污染物的光催化复合材料（PC）。本文深入探讨了污染物产生对环境的影响，以及在 PC 中使用二氧化钛和掺杂二氧化钛降解二氧化氮（NOx）、挥发性有机物和有机染料的概念。本文明确讨论了评估上述污染物降解效率的方法。本综述介绍了与污染物降解相关的各种影响参数的共识知识，如 PC 的制备方法、光催化剂/原材料的类型和数量以及环境条件等。最后，本综述为今后的研究提出了建议。本综述使人们对基本概念有了更广泛的了解，并为该领域的创新途径提供了宝贵的见解。
A review on photocatalytic cementious composites for environment remediation
Increasing pollutants in the environment becomes one of the major critical issues these days due to rapid urbanization and industrialization. Therefore, researchers pay attention towards photocatalytic composites (PC) for the degradation of pollutants. This present paper critically looks into the environmental impact of pollutants generation and the concepts behind the use of TiO2 as well as doped TiO2 in PC for the degradation of nitrogen dioxides (NOx), volatile organic agents and organic dye. The methods for evaluating degradation efficiencies of the above pollutants are clearly discussed in this paper. This review presents consensus knowledge of various influential parameters, such as, methods of preparation for making PC, type and amount of photocatalyst/raw materials and environmental conditions, etc., associated with the degradation of pollutants. Finally, recommendations are made for future studies in this review paper. This review provides a broader understanding of basic concepts and valuable insights for avenues of innovation in this field.
期刊介绍：
International Journal of Environmental Science and Technology (IJEST) is an international scholarly refereed research journal which aims to promote the theory and practice of environmental science and technology, innovation, engineering and management.
A broad outline of the journal''s scope includes: peer reviewed original research articles, case and technical reports, reviews and analyses papers, short communications and notes to the editor, in interdisciplinary information on the practice and status of research in environmental science and technology, both natural and man made.
The main aspects of research areas include, but are not exclusive to; environmental chemistry and biology, environments pollution control and abatement technology, transport and fate of pollutants in the environment, concentrations and dispersion of wastes in air, water, and soil, point and non-point sources pollution, heavy metals and organic compounds in the environment, atmospheric pollutants and trace gases, solid and hazardous waste management; soil biodegradation and bioremediation of contaminated sites; environmental impact assessment, industrial ecology, ecological and human risk assessment; improved energy management and auditing efficiency and environmental standards and criteria.
