Abstract

Способ получения наночастиц карбида молибдена, включающий растворение пентахлорида молибдена в этаноле, добавление в раствор мочевины и последующий отжиг, отличающийся тем, что пентахлорид молибдена и этанол берут в соотношении, равном 1:1÷3, соответственно, а отжиг ведут в две стадии: со скоростью не более 5°С/мин до температуры 430-450°С в вакууме, затем до температуры 550-600°С в атмосфере азота с последующей выдержкой при этой температуре в течение 2,5-3 ч.A method of producing molybdenum carbide nanoparticles, including dissolving molybdenum pentachloride in ethanol, adding urea to the solution and subsequent annealing, characterized in that molybdenum pentachloride and ethanol are taken in a ratio of 1: 1 ÷ 3, respectively, and the annealing is carried out in two stages: from at a rate of not more than 5 ° C / min to a temperature of 430-450 ° C in vacuum, then to a temperature of 550-600 ° C in a nitrogen atmosphere, followed by exposure at this temperature for 2.5-3 hours
