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.

摘要： Abstract The invention develops a facile, effective, and low-cost method for refining the eutectic structure in Sn-Bi alloys. The refinement of the eutectic structure can be achieved as the following steps. Firstly, the pure metal tin (Sn) and bismuth (Bi) are completely melted and kept for the appropriate time at more than 200 °C to ensure that the melt becomes a homogeneous and single-phase melt. Secondly, the rare earth-containing master alloy (Sn-La, Sn-Ce, Sn-Nd, Sn-Gd, Sn-La-Ce, etc.) is added into the above melt, subsequently which is kept for the appropriate time at more than 300 °C for the same purpose as above. Finally, the melt is poured into the mold to obtain Sn-Bi casting alloy with a fine eutectic structure. After being modified with the rare earth-containing master alloy, the lamellar spacing of the eutectic structure is reduced by an order of magnitude. The remarkable refining effect mainly comes from the heterogeneous nucleation sites of the in-situ precipitated compounds (LaBi 2, CeBi 2 , NdBi2, GdBi 2, etc.) along with the interface activation of the rare earth element, which are conducive to the nucleation of the Bi-rich phase. Besides, the in-situ precipitated compounds can effectively inhibit the coarsening of grains during the material service, dramatically improve the practical service strength of the welded joint, and markedly extend the service life of the joint. The refining method in the invention is feasible for industrial production, Therefore, the invention has a great application potential and high commercial value. Figure Figure 4

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.
