Abstract

The invention discloses a Co-Se compound nanotube@ foam Ni composite array material as well as a preparation method and an application thereof. The method comprises the following steps: firstly, Co salt and urea are dissolved in deionized water, foam Ni is added, and a Co precursor@ foam Ni composite is prepared through a hydrothermal reaction; then a Se source is dissolved in hydrazine hydrate, the obtained solution is mixed with deionized water, the Co precursor@ foam Ni composite is added, and the Co9Se8 nanotube@ foam Ni composite array material is obtained through a hydrothermal reaction.The raw materials and process equipment are simple, the preparation cost is low, the product yield is high, and the prepared composite is a 1D hollow-structured Co9Se8 nanotube array directly growingon a foam Ni substrate with good electrical conductivity, can directly serve as an electrode material to be applied to catalysis of water electrolysis for a hydrogen evolution reaction, shows excellent catalytic performance and has huge potential application value in the field of water electrolysis for hydrogen production.

Description

technical field

[0001] The invention relates to the technical field of preparation of micro-nano materials, in particular to a cobalt-selenium compound nanotube@foam nickel composite array material and its preparation method and application. Background technique

[0002] With the continuous increase of global fossil fuel consumption, people have brought very serious environmental problems. For example, smog, the warming global climate, etc. are all the impacts of long-term and large-scale use of fossil fuels. In addition, fossil fuels such as coal, natural gas and petroleum are also facing the problem of depletion due to the difficulty of regeneration in a short period of time. Therefore, the development of efficient, clean and renewable energy has become an urgent task for the scientific community in the 21st century. Among various sustainable energy sources, hydrogen is considered as one of the most promising candidates to replace traditional fossil fuels in the future. ...
