The invention discloses a method for obtaining a multi-channel modified graded catalytic material through an in-situ decomposition technology, and belongs to the field of nanometer material preparation technologies and photochemical application. The graded catalytic material is obtained by taking transition metal molybdate as a structural cutting body and based on an in-situ decomposition technology under a water bath condition: preparing a molybdate nano material by adopting a hydrothermal method; and weighing molybdate, uniformly dispersing the molybdate in a solvent, carrying out ultrasonic treatment, weighing a zinc source, an indium source and a sulfur source, adding the weighed molybdate, indium source and sulfur source into the solution, carrying out stirring dissolution, carrying out a full reaction under a water bath condition, and carrying out centrifugal separation, cleaning and drying on the product to obtain the multi-channel modified graded catalytic material. The multi-channel modified graded c
