Complete manuscript data（SEM，Origin，TEM and The Design of Experiments images）

Using CAD to draw the test bench, different from the drainage method for calculating hydrogen release, this experiment collects data through a flow meter to reduce errors. The carrier samples prepared by solvothermal method were characterized by XRD, SEM, BET and other methods. Using Origin drawing. The sample characterization methods for catalysts are the same as above, and XPS spectra have been added. The hydrogen release maps are all drawn using Origin. There are 26 datasets submitted this time, including individual and group graphs. The chart names are labeled in Excel according to their numbers and correspond one-to-one in the compressed file.
