i am working with MOFs based composites. suppose i want to make binary composites of CdS/MOF if i take 500mg of MOF then how could i take the CdS in diffrent wt% like 10 %,20%,25% etc? in the same way in tertiary composites like Cu/TiO2/MOF then want to take Cu in wt% so how to calculate the amount by a proper formula?
