Fabrication of a Lateral Heterostructure of Crystallized MoO2/Amorphous MoO3‐x for Photothermal Conversion

Abstract The heterostructure of crystallized MoO 2 /amorphous MoO 3‐x was firstly constructed via reduction of crystalline MoO 3 by Mo metal via a hydrothermal method. All characterization results indicate the coexistence of a defective crystallized MoO 2 phase and amorphous MoO 3‐x phase. Furthermore, the heterostructure products possess excellent photothermal conversion (61.5%).
