| 英文摘要 | Multicomponent nickel-iron alloy nanoparticles supported on hydrochar were synthesized by a facile one-step hydrothermal strategy. Spinel nickel ferrite (NiFe2O4) with a small crystalline size around 10 nm was uniformly dispersed on a bimetallic catalyst. The roles of the Ni/Fe doping concentration and calcination temperature in tailoring the phase, morphology and size of the Ni-Fe alloy nanoparticles were investigated. To probe the catalytic abilities of the prepared bimetallic catalysts, a two-stage reaction system was applied for steam gasification of sewage sludge. Compared to monometallic nickel nanoparticles, the synthesized bimetallic catalyst, especially Ni0.25Fe0.25/HC calcined at 700 degrees C, showed excellent dispersibility of the Ni-Fe alloy NPs and exhibited a strong metal-support interaction, which allowed for better suppression of carbon deposition and nanoparticle agglomeration in the reforming process. The best catalytic performance resulted in a promoted hydrogen selectivity of 113.7 g H-2 per kg sludge with a low tar yield of 2.3 mg g-1 under mild gasification conditions. These shape-and size-modulated nanocatalysts harbor promising potential for their application as a highly efficient catalyst for hydrogen production via steam gasification of sewage sludge. |
