The invention relates to a controllable synthesis method of a nickel phosphide micro-nano material. The method includes the following steps: dissolving a certain amount of soluble nickel salt into deionized water, adding a proper amount of fully ground red phosphorus to obtain a suspension, placing the suspension into an ultrasonic cleaning machine for 1-3 hours, transferring the suspension into an autoclave, heating to 90-180 DEG C and carrying out a hydrothermal reaction for 6-18 hours. The obtained micro-nano material is Ni2P or Ni12P, and the morphology of Ni2P or Ni12P is densely packed nanoparticles with the particle size of 60-120 nm. Compared with the prior art, the non-toxic red phosphorus is used as a phosphorus source; without the presence of a surfactant, pure Ni2P or Ni12P5 can be obtained through changing the ratio of nickel to phosphorus, the hydrothermal temperature and the hydrothermal time; the method is lower in reaction temperature, shorter in reaction time, environment-friendly and applicable to mass production; the prepared nickel phosphide micro-nano material shows good catalytic performance in aspects of adsorption removal of heavy metals and photocatalytic degradation of organic dyes.
