• sample is characterized by a combination of type–IV and type–I isotherms, indicating the presence of micro- and mesopores with monolayer–multilayer adsorption. Furthermore, two distinct pore distribution curves are observed in the inset of Figure 5c revealing a hierarchical porosity: micro/mesopores

• smaller than 5 nm and meso/macropores with diameters of 20–60 nm. As shown in Table 1, the NiMoO4@Co3O4/CA sample has the largest SBET of 334.47 m2/g and Vtotal of 0.8 cm3/g, much higher than that of CA (87.7 m2/g, 0.3 cm3/g) and NiMoO4/CA (94.9 m2/g, 0.4 cm3/g).
