Abstract Biomass conversion has been developed by testing various metal based carbon catalysts. Most of the reported catalysts either use very expensive metals or support that provides lower selectivity. In this context, we fabricated new carbon based nanocomposites and studied their catalytic application for furfural reduction – a promising biomass derived molecule. The mono (Cu, Co and Ni) and bimetallic (CuCo and CuNi) nanoparticle supported on commercial graphite (CG) were prepared and characterized by TEM, EDS, XRD and Raman spectroscopy. The analysis revealed that the nanocomposites are made up of metallic nanoparticles with average particle size of 5–13 nm on the graphite matrix. The obtained results indicated that the Cu+Ni@CG catalyst exhibited high catalytic activity for furfural reduction, thus leaving Cu+Ni as the finest and cost effective catalyst for this study.

多功能碳负载单金属和双金属纳米复合材料：合成、表征及其在糠醛还原中的潜在应用

摘要 通过测试各种金属基碳催化剂，已经开发了生物质转化。大多数报道的催化剂要么使用非常昂贵的金属，要么使用提供较低选择性的载体。在这种情况下，我们制造了新的碳基纳米复合材料，并研究了它们在糠醛还原（一种有前途的生物质衍生分子）中的催化应用。制备了负载在商业石墨 (CG) 上的单金属（Cu、Co 和 Ni）和双金属（CuCo 和 CuNi）纳米颗粒，并通过 TEM、EDS、XRD 和拉曼光谱对其进行了表征。分析表明，纳米复合材料由石墨基体上平均粒径为 5-13 nm 的金属纳米颗粒组成。所得结果表明，Cu+Ni@CG 催化剂对糠醛还原表现出较高的催化活性，
