摘要
Abstract
The escalating environmental pollution resulting from economic growth poses a significant threat to both the ecological balance and human health.Among a group of materials,metal-organic skeletons(MOFs)have a broad prospect in the field of pollutant adsorption.However,the rigid structure and powder morphology of MOFs severely limit their applications,so it is necessary to find a suitable carrier to broaden the application pathway of MOFs.As the global non-renewable resources are getting less and less,renewable green cellulose is gradually coming into the public's attention.Wood sponge(WS)with hierarchical and tubular porosity is a new type of environmentally friendly material developed in recent years,which has the advantages of high porosity and large specific surface area,and the composite of MOFs and WS is expected to achieve high-capacity adsorption of organic pollutants.In this paper,a composite material of ZIF-8@PWS was designed to address the problems of weak mechanical strength of MOFs and low adsorption capacity of organic pollutants.Firstly,WS was biomimetically mineralised using dopamine to obtain a wood sponge(PWS)covered with dopamine on the surface,followed by the growth of zeolite imidazolium ester skeleton(ZIF-8)on the surface of PWS.The adsorption capacity of the composite material for MB could reach 151.3 mg/g in 180 min,which has good adsorption performance.关键词
