摘要

亚甲基蓝（MB）是一种环境污染物，由于其在水中的过度使用和自然降解能力差，对环境和人类健康造成危害。本研究开发了一种新的异质结催化结构。采用静电纺丝法制备了壳聚糖- zif -8绿色纳米材料，用于光催化降解MB。ZIF-8增强了材料的比表面积和电子导电性，从而提高了光催化效率。ZIF-8含量的增加显著提高了光催化效率，0.5 g ZIF-8在25 min内对MB的降解率达到98.13%。该材料还表现出很强的重复性和稳定性，在空气中30天后保持96.5%的降解效率。本研究为环境和水处理提供了一种高效、低成本的新型材料。

Green Synthesis of ZIF-8/Chitosan Nanofiber Membranes for Catalytic Degradation of Methylene Blue

Methylene blue (MB) is an environmental pollutant that harms the environment and human health due to excessive use and poor natural degradation in water. In the present study, a new heterojunction structure for catalysis was developed. A chitosan-ZIF-8 green nanomaterial was fabricated via electrospinning to degrade MB photocatalytically. ZIF-8 enhanced the specific surface area and electron conductivity of the material, thus boosting photocatalytic efficiency. Higher ZIF-8 content raised photocatalytic efficiency notably, with 0.5 g ZIF-8 achieving 98.13% MB degradation in 25 min. The material also demonstrated strong repeatability and stability, maintaining 96.5% degradation efficiency after 30 days in air. This study produced an efficient low-cost novel material for environmental and water treatment applications.

期刊介绍： Water, Air, & Soil Pollution is an international, interdisciplinary journal on all aspects of pollution and solutions to pollution in the biosphere. This includes chemical, physical and biological processes affecting flora, fauna, water, air and soil in relation to environmental pollution. Because of its scope, the subject areas are diverse and include all aspects of pollution sources, transport, deposition, accumulation, acid precipitation, atmospheric pollution, metals, aquatic pollution including marine pollution and ground water, waste water, pesticides, soil pollution, sewage, sediment pollution, forestry pollution, effects of pollutants on humans, vegetation, fish, aquatic species, micro-organisms, and animals, environmental and molecular toxicology applied to pollution research, biosensors, global and climate change, ecological implications of pollution and pollution models. Water, Air, & Soil Pollution also publishes manuscripts on novel methods used in the study of environmental pollutants, environmental toxicology, environmental biology, novel environmental engineering related to pollution, biodiversity as influenced by pollution, novel environmental biotechnology as applied to pollution (e.g. bioremediation), environmental modelling and biorestoration of polluted environments. Articles should not be submitted that are of local interest only and do not advance international knowledge in environmental pollution and solutions to pollution. Articles that simply replicate known knowledge or techniques while researching a local pollution problem will normally be rejected without review. Submitted articles must have up-to-date references, employ the correct experimental replication and statistical analysis, where needed and contain a significant contribution to new knowledge. The publishing and editorial team sincerely appreciate your cooperation. Water, Air, & Soil Pollution publishes research papers; review articles; mini-reviews; and book reviews.
