摘要： The invention is in the technical fields of biomass resources utilization and preparation of electrode materials, and involves a method of preparing carbon supported transition metal sulfide electrode materials, especially a preparing method using bio-oil derived from biomass as carbon source. Typically, the sulfate solution is firstly prepared via dissolving the transition metal sulfate (such as nickel sulfate or cobalt sulfate) into methanol/water solution. Secondly, the bio-oil is collected from pyrolyzing biomass at 600-1000°C for 10 to 120 min in a flowing inert atmosphere. Finally, the carbon supported transition metal sulfide electrode materials can be obtained after calcined the collected bio-oil containing sulfate and ground. The prepared electrode materials based on the pyrolysis bio-oil display the superb supercapacitor performances: more than 1000 F/g at the current density of 1.0 A/g. Furthermore, the biomass as raw material has the advantages of low price, green sustainability, and the preparation process is facile and easy for industrial production. Besides, the invention develops and provides a new way for the high value conversion of biomass resources and the preparation of carbon-based transition metal sulfide electrode materials.

According to the method for making wood-converted carbon fiber paper, wood is used as a precursor and subjected to a conventional papermaking process, the wood is cooked into a stock; the stock is washed, screened, and beaten into a pulp; finally, the pulp is subjected to a papermaking process to obtain a paper; the paper is calcinated at a high temperature under a preotection of nitrogen, to obtain a carbon material. As the wood is of an amorphous structure microstructurally, a conversion from an amorphous structure to a fibrous structure is achieved through the papermaking process, and a wood-converted carbon fiber paper is then obtained through carbonization. According to the method for making a wood-converted carbon fiber paper, wood that has rich resources is used as a raw material; the method has advantage of energy saving and consumption reduction; by means of a complete papermaking process and a simple carbonization method, a stable carbon fiber paper could be obtained efficiently, and research on controllable biomass energy morphology and biomass-based carbon material application are widened.

摘要： The present disclosure provides a method for preparing a bacterial cellulose-based antibacterial material, and relates to the technical field of antibacterial materials. Using bacterial cellulose as a substrate and silver nitrate as a silver resource of a silver plating solution, silver ions could be reduced into elemental silver under an alkaline environment provided by ethylenediamine; as trifluoroacetic acid has a catalytic function, a silver ion complex is produced by catalysis, favoring the reduction of silver ions into elemental silver; the silver ions in the silver plating solution are thoroughly reduced into silver particles by a potassium sodium tartrate tetrahydrate solution; the silver particles are loaded onto the bacterial cellulose to obtain the bacterial cellulose-based antibacterial material. According to the method, the biomass bacterial cellulose that has rich sources is used as a raw material, and the mehod broadens the application of natural biomass resources in the field of antibacterial materials. Besides, by the method, stable, uniform and high-amount supporting of silver nanoparticles could be realized at ambient temperature and in a short time to form a silver-loaded bacterial cellulose-based antibacterial material, favoring energy saving and consumption reduction.

摘要： This invention belongs to the technical fields of biomass resource utilization and catalyst preparation, and involves a method of preparing carbon supported transition metal catalysts, especially a method of preparing carbon supported transition metal catalysts for hydrogenation from bio-oil. Typically, the nitrate (nickel nitrate, cobalt nitrate or copper nitrate) is firstly dissolved into alcohol/water solution. Subsequently, the bio-oil pyrolyzed from biomass is absorbed with the solution. The solution is dried up after the pyrolysis reaction is over. Finally, the carbon supported transition metal catalysts for hydrogenation can be obtained after calcined and ground. In the invention, low-price and easily accessible biomass is adopted as the initial raw material. The obtained carbon supported transition metal catalysts display outstanding hydrogenation activity of furfural and selectivity towards furfuryl alcohol or tetrahydrofurfuryl alcohol, and exhibit wide application prospect and high commercial values. In addition, the preparation method adopted in the invention is universally applicable, and provides a new approach and idea for the high-value conversion of biomass resources and the preparation of carbon supported transition metal catalysts for hydrogenation.
