The strategic design of the heterojunction photocatalyst with an enhancement in charge transfer rate photogenerated carriers plays a key role wastewater treatment to remove organic pollutants. In current study, g-C3N4/SnO2 quantum dots (g-CN/c-SQDs) different ratios SQDs was prepared via sonochemical route. Z scheme for g-CN/c-SQDs visible light exhibits exceptional degradation performance RhB dye (98.25 % 40 min) cyclic stability. photocatalytic efficiency is ascribed efficient and redox reactions due between high surface areas g-C3N4 c-SQD, which evident from results photoluminescence spectra scavenger experiments. free radical capture experiments reveal electron pathway generation reactive oxygen species (ROS) generation, including superoxide (•O2–) hydroxyl (•OH) radicals has been involved process. This study provides insight construction Z- appropriate amount semiconductor photodegradation treatment.

The enhancement of efficient, visible-light active photoanodes is vital for advancing photoelectrochemical (PEC) water splitting as a sustainable and environmentally friendly energy alternative. In this study, we explore the potential WO3/CuWO4/Ag heterojunction thin films fabricated by magnetron sputtering on n-Si substrates viable photoanodes. synergetic effects formation Ag nanoparticle dispersion contribute to superior absorption, charge transfer, separation efficiency. influence decoration achieved through solid-state dewetting phenomena was studied in terms structural microstructural changes responses. Surface topography observations revealed that film exhibited highest surface area ratio 22.7%, approximately threefold increase compared pure WO3 films. photoluminescence (PL) time-resolved (TRPL) results demonstrated configuration promotes effective an increased carrier lifetime ∼20.1 ns. PEC analysis showed substantial photocurrent density 1.53 mA cm–2 (1.0 V vs Ag/AgCl), 2.32 times greater than WO3, applied bias photon-to-current efficiency (ABPE) 0.91%, 0.43% 0.50% WO3/CuWO4 Moreover, photoanode remarkable long-term stability with current 0.21 about 4.5 h. These findings underscore photocatalysts emphasize significance effect structure achieving clean hydrogen production. Additionally, research may inspire further studies plasmon metal controlled size shape, using simple technique development efficient electrodes next-generation applications.

Coupling TiO2 with various elements could enhance its photocatalytic activity. In this study, an innovative ultrasound-assisted sol–gel method was used to synthesize TiO2/Ag(x%) by varying Ag–support mass (x = 9.3, 17.1, and 23.6%), followed calcination at 450 °C for 30 min. The aim demonstrate that Ag compositing improves photoactivity under visible light (>400 nm). synthesized photocatalysts were assessed their effectiveness in the degradation mineralization of Methylene Blue (MB) Acid Orange 7 (AO7) using lamps emitting range 400–800 nm. Characterization prepared performed Raman spectroscopy, SEM/EDS, pHpzc, UV–visible spectroscopy. spectroscopy confirmed predominance anatase phase all photocatalysts. photodegradation efficiencies selected dyes, MB AO7, reached 99% (pH 6) 95% 3) after 180 min irradiation, respectively. best performance two dyes observed TiO2/Ag9.3%, showing optimal kinetics doping concentration. improved TiO2/Ag composite is due a decrease recombination rate electron/hole (e−/h+) band gap from 3.13 2.49 eV. both about 9.3%, indicating presence refractory by-products resist complete degradation. Under UVA obtained. This study confirms potential as high-performance cost-effective photocatalyst solar environmental remediation, highlighting role silver extending absorption into region improving charge separation.
