The specific surface areas and pore volumes of the prepared samples were further analyzed by nitrogen adsorption-desorption isotherm measurement.The image in the inset in Fig.4 shows that all the samples had a mesoporous pore size(approximately 25–30 nm).Furthermore,according to the IUPAC classification,both isotherms belong to type IV physisorption isotherms.The characteristic features of this type of isotherm are its hysteresis loop associated with capillary condensation occurring in the mesoporous structure,and the limiting uptake in the range of high relative pressure[36,37].The as-prepared photocatalysts displayed an H3-type hysteresis loop(P/P0>0.4),which may have resulted from the Mo S2nanoflowers consisting of several ultra-thin Mo S2 nanosheets overlapping each other.The BET surface area measurements of pure Mo S2 and 3%-Ag VO3/Mo S2 were 17.36 and 7.71 m2 g-1,respectively,demonstrating that the introduction of Ag VO3influenced the surface area.The specific surface area and pore volume calculated from the isotherms are summarized in Table1.
