Ultrasonic processing of WO(3) nanosheets integrated Ti(3)C(2) MXene 2D-2D based heterojunctions with synergistic effects for enhanced water splitting and environmental remediation

This article describes a straightforward chemical procedure that involves hydrothermal and ultrasonic treatments to create a new 2D/2D ultrathin WO(3)/Ti(3)C(2) heterojunctions. The features of the fabricated heterojunctions were characterized and examined by field emission electron microscopy (FESEM), transmission electron microscopy (TEM), X-ray diffraction (XRD), optical absorption spectroscopy (UV–Vis). By photodegrading an organic dye under the influence of visible light, the photocatalytic degradation capabilities of the heterojunctions were also investigated. The performance of WO(3)/Ti(3)C(2) was superior to that of bare WO(3), with a removal rate of 94% and a kinetic rate constant (k) that was approximately 3 times that of WO(3). The creation of 2D/2D heterojunction was observed to encourage the spatial charge separation and increase the surface reactive sites, to result with the increased photocatalytic activity in WO(3)/Ti(3)C(2) heterojunction. The photocurrent values discovered through photoelectrochemical studies further indicated Ti(3)C(2)′s active function in enhancing water-splitting performance. The impedance analysis examined by an electrochemical method revealed that heterojunctions might be helpful in accelerating the migration of charges quickly to get the outcomes seen.
