摘要
As oil is now an important resource for the survival and development of mankind,the consumption of oil continues to increase each year,and there have been a number of major oil spills in history,such as the oil spill from the Deepwater Horizon drilling rig.Therefore,oil spills during storage and transportation have become an issue of serious concern.Current methods such as incineration and chemical methods cause secondary environmental pollution and fail to enable resource recovery.The adsorption method by porous materials has attracted worldwide attention due to its simplicity,portability,and efficiency.It has become an important factor to explore how porous adsorption materials can adsorb efficiently and reduce environmental pollution.Biomass resources are abundant,cost-effective,biodegradable,and sustainable,which have been extensively explored for the production of porous materials.Herein,recent advances in cellulose-based,chitosan-based,wood-based and other biomassbased oil-absorbing porous materials are summarized,and cellulose-based porous materials,such as nanocellulose,bacterial cellulose,and regenerated cellulose and their related derivatives,are further expanded.In addition,typical environmentally friendly manufacturing methods and the oil adsorption capacities of various oil-absorbing porous materials are also discussed.Compared with the traditional petrochemical adsorption materials,the development advantages of biomass porous oil absorption materials are analyzed.The reasons hindering the popularization and use of oil-absorbing biomass materials are summarized and the future application fields are prospected.
