Powder X-ray Diffraction (PXRD), Energy Dispersive Spectroscopy (EDS), High-Resolution Transmission Electron Microscope (HR-TEM), Brunauer-Emmett &amp; Teller (BET) method, X-ray photoelectron spectroscopy (XPS), Ultraviolet–Visible Diffuse Reflectance Spectroscopy (UV- DRS), and photoelectrochemical studies were used to investigate the formation of GO-TiO₂-WO₃ (GTW) nanocomposite.

HR-TEM data shows the uniform distribution of TiO₂ and WO₃ nanoparticles on the GO sheet. BET analysis shows the synthesized nanocomposite has higher surface area which enhanced the pollutant adsorption ability of GTW composite to greater extent. The photoelectrochemical analysis confirms the GTW nanocomposite is an active photoelectrocatalyst and is a n-type semiconductor which is sufficiently reproducible over several light-on–off cycles. The photocatalytic degradation in presence of GTW nanocomposite was found to be 99 %, 94 %, and 93 % for MB, CR and MG dyes, respectively. The photocatalytic degradation for antibiotic and organic compound was also carried out using GTW nanocomposite and the results obtained were 88 % and 87 % for azithromycin and phenol, respectively.

Although their energy density is 2 to 4 times greater than that of supercapacitors, it still remains relatively low and requires further improvement. According to the equation E = 1/2 CU2, the stored energy E is proportional to the capacitance C and the square of the voltage U. Consequently, increasing the operating voltage of the device presents a viable approach for developing lithium-ion capacitors with high energy density. However, as the voltage rises, irreversible side reactions may take place at the capacitor’s positive electrode, resulting in a decrease in over all cycle life. In this study, the precursor of solid-state coating was thoroughly mixed with activated carbon in a liquid-phase environment, and subsequently, the solid-state reaction method was utilized to coat LiAlO₂ on the surface of the activated carbon positive electrode. The research results indicate that the coated materials can effectively improve the occurrence of irreversible reactions between the activated carbon positive and the electrolyte, thereby enhancing its cycle life at high voltages.
