Recently, PhD student Mr Pei-dong Wu supervised by Profs. Hu Li and Zhen Fang <\/strong>published a research article in Advanced Sustainable Systems<\/strong> about bimetallic synergistic catalysis for reductive amination of bio-based levulinic acid.<\/p>\n

Bimetallic synergy and carbon-nitrogen doping can contribute to enhanced catalytic activity due to the strong electronic state and unique geometrical structure. In this work, a series of biomass-derived Co-M bimetallic C-N doped catalysts (Co-M@Chitosan-X; M = Zr, Ni, Fe, Cu, In; X denotes the molar percentage of M) were prepared via simple oil bath reflow and annealing. The Co-Zr@Chitosan-X catalysts were determined to contain alloy (Co-Zr), metal-carbon bond (Co-C, Zr-C), metal-nitrogen bond (Co-N, Zr-N) and metal oxide (Co3<\/sub>O4<\/sub>, ZrO2<\/sub>) through a series of characterizations, in which graphite-coated alloys and metal oxides were catalytically active species. The doping of the second metal results in a significant enhancement for the number of active sites in the catalyst, and the d-band center is shifted toward a deviation from the Fermi energy level. Among the tested catalysts, Co-Zr@Chitosan-20 exhibited superior catalytic activity for the reductive amination of bio-based levulinic acid to 5-methyl-2-pyrrolidone in 99.3% selectivity and 92.8% yield. This non-noble metal bimetallic synergistic catalytic protocol opens an avenue for efficiently producing biomass-derived nitrogenous chemicals.<\/p>\n

Non-noble bimetallic nanoparticles (Co-Zr\/CNx<\/sub><\/em>) were efficient for direct conversion of bio-based levulinic acid (LA) to 5-methyl-2-pyrrolidone (5-MP) in water at 130 \u00b0C. Synergistic role was found in the reductive amination process with high activity over a long period of time in one-pot reactions. \u975e\u8d35\u91d1\u5c5e\u53cc\u91d1\u5c5e\u7eb3\u7c73\u7c92\u5b50\uff08Co-Zr\/CNx<\/sub><\/em>\uff09\u5728130\u2103\u7684\u6c34\u4e2d\u80fd\u6709\u6548\u5730\u5c06\u751f\u7269\u57fa\u4e59\u9170\u4e19\u9178\uff08LA\uff09\u76f4\u63a5\u8f6c\u5316\u4e3a5-\u7532\u57fa-2-\u5421\u54af\u70f7\u916e\uff085-MP\uff09\u3002\u5728\u5355\u9505\u53cd\u5e94\u4e2d\u8fd8\u539f\u80fa\u5316\u8fc7\u7a0b\u4e2d\u53d1\u73b0\u53cc\u91d1\u5c5e\u50ac\u5316\u5242\u957f\u65f6\u95f4\u5177\u6709\u9ad8\u6d3b\u6027\u3002<\/p>\n
