Method for preparing Ni2P by reducing nickel oxide precursor through thermal treatment at low temperature
TLDR
In this paper, a novel method for preparing nickel phosphide (Ni2P) by utilizing phosphine produced by thermal decomposition of sodium hypophosphite to reduce nickel oxide precursor is presented.Abstract:
The invention provides a novel method for preparing nickel phosphide (Ni2P) by utilizing phosphine produced by thermal decomposition of sodium hypophosphite to reduce nickel oxide precursor In the method, nickel nitrate is adopted as a nickel source and then roasted to obtain nickel oxide, and the obtained nickel oxide is dipped into sodium hypophosphite solution to obtain the nickel oxide precursor, and simple low temperature thermal treatment of the nickel oxide precursor is carried out so as to synthesize supported and unsupported Ni2P The invention has the characteristics of simple process, low Ni2P preparation temperature, short production period, without the complex steps of temperature programming, and the like as well as just simple thermal treatment at normal temperature Raw materials used in the method are low in price and safety, and devices used in the method are low in cost The catalyst can be widely used for hydrogenation treatment of oils due to higher hydrodesulfurization and hydrodenitrogenation activitiesread more
