摘　　要：本工作首次报道了一种高磷铁矿协同纯Ca_(3)(PO_(4))_(2)熔融还原并结合单辊旋淬技术制备Fe-P合金带材催化剂的短流程冶金工艺,该工艺具有成本低、产品附加值高、易于工业化的优点。针对电催化析氢合金催化剂低成本高效制备难题,国内外学者进行了重点研究。因此,通过短流程冶金的方法制备Fe-P合金带材催化剂并将其用于电催化制氢(HER)领域,一方面降低了冶金过程中二氧化碳和其他大气污染物的排放,另一方面为冶金资源实现“大型化、清洁化、连续化、自动化”再利用平台搭建提供了指导方案,有望解决催化剂技术在发展中存在的“卡脖子”问题。A novel strategy for the direct production of Fe-P alloy ribbon catalysts by smelting reduction of high-phosphate iron ore and apatite combined with single-roller melt-spinning technology was proposed.This short-metallurgical process demonstrates the advantages of low cost,high value-added and easy industrialization.Previous researches have been devoted to addressing the preparation of low-cost and efficient alloy-based catalysts for electrocatalytic hydrogen evolution(HER).Therefore,the preparation of Fe-P alloy ribbon catalysts through short-metallurgical process and their applications in the field of HER can not only reduce the emission of carbon dioxide and environment pollutants during the metallurgical process,but also provides a guidance to the construction of a‘large-scale,clean,continuous,and automated’reuse platform for metallurgical resources,which is highly expected to solve the‘bottleneck’problem in the development of catalyst technology.
