BiVO4 is a stable photocatalytic material but has poor activity in visible light. Herein, the surfactants were investigated to enhance degradation of tetracycline (TC) through hydrothermal method. The different molecular structures and properties surfactant-modified show clustered small spheres stacked plate-like microcrystals. N-hexadecyltrimethylammonium chloride (CTAC)-modified (BiVO4-CTAC) with morphology increases light absorption range decreases energy band gap. Surfactants hydrophilic groups affect formation process BiVO4, regulating morphology, crystal structure, crystalline surface exposure BiVO4. BiVO4-CTAC demonstrated superior TC efficiency compared original (BiVO4-Blank). This enhancement attributed observation Nyquist plot, where exhibits smallest arc radius, indicative reduced charge transfer resistance improved separation. Furthermore, holes (h+) superoxide radicals (•O2–) reactive species are main active for degradation. study develops novel method synthesize monoclinic phase lamellar materials by simply changing surfactant type. holds potential implications advancing surfactant-assisted synthesis high-efficiency photocatalysts.

Natural benzaldehyde, an important spice-type flavor component and raw pharmaceutical material, is scarcely due to the escalating demand consumer preference for natural foods. To mitigate this issue, present study aimed investigate oxygen-driven selective oxidation of cinnamaldehyde benzaldehyde under visible light. K2B4O7·4H2O KBH4 were used as boron sources modify g-C3N4 photocatalyst regulating conversion rate selectivity. A series characterization techniques revealed improvements in photocatalytic performance modified catalysts─that is, doped with derived from or (BCN KBCN, respectively; 10% 25% increase rate, 11% 34% selectivity). These enhancements generated nitrogen vacancy. Moreover, abilities BCN KBCN adsorb oxygen improved. The conjugated aldehyde group planar molecular structure are critical >C═C< unit obtain aldehyde. mechanism underlying action was established, reasons superior compared that determined. Essentially, reducible source─KBH4─produced a radical site on surface g-C3N4, which collided •O2– generate another vital species 1O2. Subsequently, electrons transferred could be captured by adsorbed molecules regenerate •O2–. Furthermore, hole produced catalyst during visible-light illumination promoted its reaction obtaining electron cinnamaldehyde. Overall, paves way future applications research α,β-unsaturated carbonyl compounds.

A Z-scheme heterojunction photo(electro)catalyst was fabricated by coupling sulfonic acid-modified graphitic carbon nitride (SA-g-CN) with bismuth oxyiodide (BiOI). The SA-g-CN component prepared via wet-impregnation, while BiOI synthesized through a hydrothermal method. Comprehensive characterization elucidated the structural and morphological properties of resulting composite. SA-g-CN/BiOI exhibited exceptional performance in both photocatalytic degradation tartrazine (TTZ) photoelectrochemical oxygen evolution reaction (OER). Notably, 98.26% TTZ removal achieved within 60 min irradiation, an OER onset potential 0.94 V (vs. Ag/AgCl) high photocurrent density 6.04 mA were recorded under AM 1.5G illumination. Band energy calculations based on Mott–Schottky measurements confirmed formation heterojunction, which facilitated efficient charge separation transfer, thereby enhancing catalytic activity. These findings establish composite as promising candidate for sustainable generation environmental remediation applications.
