Summary: A novel S-scheme Au/g-C3N4/BiO1.2I0.6 plasmonic heterojunction was constructed for the first time, exhibiting excellent photocatalytic activity under visible light irradiation. The high photocatalytic performance was attributed to the high efficiency of charge separation and the excellent light absorption of localized surface plasmon resonance (LSPR) caused by Au deposition.

Summary: In this study, a g-C3N4/PDI-g-C3N4 homojunction was fabricated for piezo-photocatalytic atrazine removal, demonstrating superior performance compared to individual photocatalysis or piezocatalysis. The introduction of PDI facilitated electron migration and enhanced piezoelectricity, with the homojunction promoting photoelectron transfer. The porous structure of the g-C3N4/PDI-g-C3N4 was found to be essential for the enhanced piezoelectricity, leading to a high atrazine degradation rate and H2O2 production during the piezo-photocatalytic process.

Summary: The widespread use of antibiotics has led to serious environmental issues, and there is an urgent need for new treatments to remove these substances from wastewater. In this study, a new approach using the NiFe2O4/g-C3N4 heterostructure was proposed to activate peroxymonosulfate (PMS) under visible light (VL) for degradation of tetracycline hydrochloride (TCH) in simulated wastewater. The NiFe2O4/g-C3N4/PMS/VL system effectively removed TCH over a wide pH range and in the presence of various anions commonly found in wastewater. The superior degradation performance of the composite was attributed to the synergistic effect between heterojunction photocatalysis and PMS activation, generating highly oxidizing species that effectively degraded TCH. Additionally, the magnetic properties of the heterostructure facilitated separation and reuse of the photocatalyst.

Summary: In this study, resorcinol formaldehyde (RF) was introduced for photothermal catalytic generation of H2O2, achieving a photosynthetic yield of approximately 2000 mu m within 40 min under solar irradiation. The solar-to-chemical conversion (SCC) efficiency reached up to 0.19% at 338 K, surpassing photocatalysis with a cooling system by a factor of about 2.5. The H2O2 generated by RF during the photothermal process was formed through a two-channel pathway, promoting overall H2O2 formation and enabling its usage for pollutant removal. This work provides a sustainable and economical route for efficient H2O2 synthesis.

Summary: Heterojunction construction and defect engineering were combined to improve the CO2 photoreduction activity of Cu1.95S@CuS. The Z-scheme Cu1.95S@CuS heterostructure reduced charge carrier recombination and enhanced the directional carrier transfer, resulting in strengthened CO2 activation and photoreduction activity. The CO2 photoreduction pathway was explored by in situ Fourier transform infrared spectroscopy, and density functional theory calculations showed that surface Cu vacancies and heterojunction interfaces lowered the energy barrier for the rate determining step, enabling spontaneous reduction reaction. This work provides a strategy for designing heterojunction and deficient photocatalysts for solar energy conversion.

Summary: This review introduces the application of covalent triazine frameworks (CTFs) and their derivatives in sustainable electrochemical energy storage and conversion (EESC). Although CTFs have merits such as large surface area, tailorable conjugated structures, and excellent chemical and thermal stabilities, their poor conductivity limits their electrochemical performances. To overcome this challenge, CTF-based nanocomposites and derivatives like heteroatom-doped porous carbons have been proposed. This article also highlights the synthesis strategies for CTFs, the progress in electrochemical energy storage and conversion, and provides recommendations for the further development of CTF-based nanomaterials in EESC research.
