Zusammenfassung:In this research, a novel LaCdSe-GO-TiO 2 (LCS-G-T) has been synthesized by utilizing a high powersonic method under controlled condition. From the structural morphology, it is apparent that the composite is a good example of size control and low-cost synthesis with an ultrasound and scavenger effect. The synthesized LaCdSe-GO-TiO 2 (LCS-G-T) composite has given a good efficiency for photocatalytic water splitting for hydrogen evolution. The implementation of high ultrasonic power has increased, the surface area decreased the particle size, due to the collapse by micro-bubbles occurred and formation of crystal enhancement. Different characterizations have been carried out for “as-prepared” composites, such as X-ray diffraction (XRD) for checking the crystallinity, scanning electron microscopy (SEM) for structural morphology, energy-dispersive X-ray (EDX) analysis, transmission electron microscopy (TEM), X-ray photoelectron spectroscopy (XPS), UV–Vis diffuse reflectance spectra (DRS), and photoluminescence (PL) spectra, and a standard three-electrode system has been used in a cyclic voltammetry test. The LaCdSe-GO-TiO 2 has exposed a good photocatalytic activity in the presence and absence of several scavengers. Moreover, the applied high powersonic for hydrogen production can significantly influence the photocatalytic activity of LaCdSe-G-T. The implemented high powersonic produces electric field bridge and helps the conversion of electron from photon.
