Preparation and properties of C/SiC composites reinforced

The results indicated that with the increase of graphite films' contents, the in-plane thermal conductivity of composites was increased from 9.78 W/(mK) to 333.34 W/(mK). Meantime, the mass loss rate reduced from 1.18 to 0.74 mg/s and the linear ablation rate reduced from 0.64 to 0.18 mm/s, revealing that the addition of graphite films could effectively improve the ablation resistance of C

Facile assembly of Cu

2020/1/1The hydrodeoxygenation of furfural to 2-methylfuran is of great significance for biomass valorization. However, the design of efficient catalysts based on non-noble metals is still a huge challenge for this transformation. In this work, a uniformly dispersed Cu-Cu 2 O/N-RGO nanocomposite was assembled via microwave assisted reduction and ammonia evaporation synthetic strategy.

Graphite

Graphite-nanoplate-coated Bi2S3 composite (Bi2S3C) has been prepared by a simple, scalable, and energy-efficient precipitation method combined with ball milling. The Bi2S3C composite was used as the cathode material for sodium-sulfide batteries. It delivered an initial capacity of 550 mAh g−1 and high stable specific energy in the range of 275-300 Wh kg−1 at 0.1 C, with an enhanced

Catalyst

The electronic and chemical properties of graphene can be modulated by chemical doping foreign atoms and functional moieties. The general approach to the synthesis of nitrogen-doped graphene (NG), such as chemical vapor deposition (CVD) performed in gas phases, requires transitional metal catalysts which could contaminate the resultant products and thus affect their properties.
