Controllable synthesis of flower-like MoSe2 3D microspheres for highly efficient visible-light photocatalytic degradation of nitro-aromatic explosives

The nitro-aromatic explosives of NB, PNP and 2,4-DNP (40 mg L⁻¹) could be completely degraded by MoSe₂ 3D microspheres for 3.5 h, 1.5 h and 2.5 h, under visible light irradiation.
