Possible reasons are as follows. The size of the water nuclear kept constant with the same ω value. When the reactant concentration increased (1 mol / L), the reactant increased in the same size water nuclear, thus the growth rate of nano crystal W increased, unable to grow well as nano-plate and self-assemble into hollow microspheres, leading to product with large size and irregular shape. When the reactant concentration was suitable (0.5 mol / L), the growth rate of the nano crystal was suitable too and W orientated growth into nano-plate, which self-assembled into hollow microspheres with the restriction of spherical water nuclear. While when the reactant concentration was 0.1 mol / L, the reactant concentration in the water nuclear was too low and growth rate of the W nano-plate was slowly, which resulting too less amount of nano-plate to self-assembled into hollow microspheres, so the resulting product was W nano-plate. |
