Summary: Dual cocatalysts consisting of Ag and transition metal oxide loaded on a CTO photocatalyst showed higher CO production rate and improved H2 evolution rate, indicating photocatalytic activity for both CO2 reduction and water splitting. Additionally, CTO photocatalysts with a single TMOx cocatalyst exhibited higher activities in H2 evolution and O2 evolution tests, suggesting an enhancement in water splitting photocatalytic activity by TMOx. On the other hand, the photocatalytic activity for water splitting was suppressed by the Ag cocatalyst.

Summary: A phosphate (PO) protection layer and various cocatalysts (Ni2P and MnOx) were synthesized on the twinned Zn0.5Cd0.5S (TZCS) photocatalyst using a two-step photochemical synthesis method. The TZCS/PO/Ni2P-MnOx composite with homojunction + protection layer + cocatalyst structure exhibited a higher initial photocatalytic hydrogen production rate compared to other photocatalysts. The excellent overall water splitting performance of TZCS/PO/Ni2P-MnOx was attributed to the efficient separation and transmission of photogenerated electron-hole pairs by the homojunction structure, as well as their capture by Ni2P and MnOx cocatalysts.

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.
