The invention belongs to the field of preparation of transition metal borides, and particularly discloses a transition metal boride, a preparation method and application thereof, and the preparation method comprises the following steps: taking reducing metal powder as a reducing agent, converting a solid-phase reaction into a liquid-phase reaction after melting, accelerating the reaction, and effectively reducing the temperature required when reactants reach a molten state. Transition metal sulfide, a reducing agent and boron powder are simply mixed and subjected to an annealing reaction under the protective atmosphere, a mixed product containing by-products and transition metal boride is obtained, and the transition metal boride is obtained after washing and drying. According to the method, the transition metal boride can be prepared only through simple mixing, annealing, washing and other steps by adopting a reducing metal auxiliary method, the difficulty of preparing the transition metal boride is greatly reduced, and transition metal boride preparation which is low in cost, simple, convenient and easy to industrialize is achieved.
本发明属于过渡金属硼化物的制备领域，具体公开了一种过渡金属硼化物、制备方法及其应用，包括：利用还原性金属粉末作为还原剂，熔融后将固相反应转变为液相反应，加速反应的进行，有效地降低反应物达到熔融态时所需的温度。通过将过渡金属硫化物、还原剂和硼粉简单混合，在保护气氛下退火反应，得到包括副产物和过渡金属硼化物的混合产物，洗涤干燥后得到过渡金属硼化物。本发明采用还原性金属辅助法，仅需简单混合、退火和洗涤等步骤，即可制备过渡金属硼化物，极大地降低了制备过渡金属硼化物的难度，实现低成本、简单方便、易工业化的过渡金属硼化物制备。
