The invention provides NiCoP nanoparticles grown on the surface of g-C3N4 in situ as well as a preparation method and application of the NiCoP nanoparticles to production of
hydrogen by photocatalytically decomposing water, and belongs to the technical field of
photocatalytic decomposition of the water to prepare the
hydrogen. The preparation method comprises the following steps: firstly, preparing g-C3N4
powder particles; then adding 10mL to 30mL of secondary
distilled water into 200mg to 400mg of the g-C3N4
powder particles; after carrying out ultrasonic treatment for 1h to 3h, stirring for 1h to 3h; then adding 10mg to 150mg of a
nickel source and 10mg to 150mg of a
cobalt source; after carrying out the ultrasonic treatment for 5min to 20min, stirring for 5min to 20min; then adding 50mgto 600mg of a phosphorous source; after carrying out the ultrasonic treatment for 1h to 3h, stirring for 1h to 3h; then
drying under the condition that the temperature is 50 DEG C to 80 DEG C; after the water is completely volatilized, sufficiently
grinding a product; then calcining for 1h to 3h in a
nitrogen atmosphere under the condition that the temperature is 200 DEG C to 400 DEG C; finally, centrifuging and washing by utilizing the secondary
distilled water and
ethanol;
drying a centrifugal product for 10h to 20h under a vacuum condition, so as to obtain the NiCoP nanoparticles grown on the surface of the g-C3N4 in situ.
