摘要

研究了以镍钴为载体的地热能废渣制氢催化剂。镍和钴由于具有良好的催化活性，在乙醇蒸汽重整中被广泛用作催化剂。以硝酸镍和硝酸钴为前驱体，采用水热法合成了地热能废物催化剂(GWC)，并采用湿浸渍法制备。SEM分析表明，镍和钴成功地粘附在GWC上，减小了GWC的表面积。在乙醇蒸汽重整中使用镍和钴产生比GWC更高的氢气产率。在550℃时，Ni/GWC的最佳产氢率为43.04%。镍可以主动断裂C-C、OH和C-H键生成氢，并降低brønsted酸位作为碳生成活性位点。

HYDROGEN PRODUCTION FROM ETHANOL BY STEAM REFORMING OVER NICKEL AND COBALT GEOTHERMAL WASTE SUPPORTED CATALYST

Hydrogen production was studied over nickel and cobalt geothermal waste-supported catalysts. Due to their good catalytic activity, nickel, and cobalt are widely used as catalysts in ethanol steam reforming. The geothermal waste catalyst (GWC) was synthesized by hydrothermal process, then prepared using wet-impregnation with nickel nitrate and cobalt nitrate as the precursors. SEM analysis shows that nickel and cobalt successfully adhered to the GWC, which decreased the surface area. Using nickel and cobalt in ethanol steam reforming produces a higher hydrogen yield than a GWC. The best hydrogen yield was 43.04% over Ni/GWC at 550oC. Nickel can actively break C-C, OH, and C-H bonds to produce hydrogen and reduces the brønsted acid site as the carbon formation active site.

期刊介绍： RASĀYAN Journal of Chemistry [RJC] signifies a confluence of diverse streams of chemistry to stir up the cerebral powers of its contributors and readers. By introducing the journal by this name, we humbly intent to provide an open platform to all researchers, academicians and readers to showcase their ideas and research findings among the people of their own fraternity and to share their vast repository of knowledge and information. The journal seeks to embody the spirit of enquiry and innovation to augment the richness of existing chemistry literature and theories. We also aim towards making this journal an unparalleled reservoir of information and in process aspire to inculcate and expand the research aptitude.
