Abstract Plant chloroplasts have a highly compartmentalized interior, essential for executing photocatalytic functions. However, the construction of reaction compartment similar to in inorganic–biological hybrid systems (IBS) has not been reported. Drawing inspiration from chloroplast and phenomenon liquid–liquid phase separation, herein, new strategy is first developed constructing subcellular system through separation technology living cells. Photosensitizers vivo expressed hydrogenases are designed coassemble within cell create compartments synergetic photocatalysis. This compartmentalization facilitates efficient electron transfer light energy utilization, resulting effective H 2 production. The (HM/IBSCS) exhibits nearly 87‐fold increase production compared bare bacteria/hybrid system. Furthermore, intracellular reactor enhance system's stability obviously, with bacteria maintaining approximately 81% their activity even after undergoing five cycles hydrogen research brings forward visionary prospects field semi‐artificial photosynthesis, offering possibilities advancements areas such as renewable energy, biomanufacturing, genetic engineering.

Photocatalysis coupling of H2 evolution and lignocellulose oxidation remain great foreground, but slow photodynamic process limits its development. Here, we explored the effect defect engineering on electronic structure d-band center Pt/TiO2 catalyst. Oxygen vacancies lead to delocalization electrons near O atom, moves down, which will redistribute facilitate desorption intermediates The density functional theory results indicate that Pt TiO2 surfaces form electron-rich electron-deficient regions, respectively. Meanwhile, in situ electron paramagnetic resonance shows thermal energy accelerated generation free radicals. Thus, rate lignin derivative conversion were effectively facilitated. Especially, efficiency thermo-photo reforming can reach 989.7 μmol g–1 h–1, is 18.2 times photo reforming. This work not only delves deeply into modulation defect-type catalysts also offers new insights efficient utilization lignin-based biomass.

In this work, protonated poly(heptazine imide) (H-PHI) was obtained by adding acid to the suspension of potassium PHI (K-PHI) in ethanol. It established that H-PHI demonstrates very high photocatalytic activity reaction hydrogen formation from ethanol presence Pt nanoparticles under visible light irradiation comparison with K-PHI. This enhancement can be attributed improved efficiency photogenerated charge transfer photocatalyst's surface, where redox processes occur. Various factors influencing system's were evaluated. Notably, it discovered conditions introduction into system significantly affect size (cocatalyst metal) deposition on thereby enhancing stability producing molecular hydrogen. operate efficiently air without additional components photocatalyst surface block access. Under optimal conditions, apparent quantum yield production at 410 nm is around 73%, highest reported value for carbon nitride materials date. The addition not only increases reduction part but also leads a value-added product ethanol-1,1-diethoxyethane (acetal) selectivity.

Abstract The synthesis and characterization of an Fe II /Fe III metal‐organic framework (MOF) nanocrystal with spatial heterogeneity that arises from the non‐uniform distribution different valence states is disclosed. ‐Ni Prussian blue analog (PBA) delivers superior photocatalytic performance in selective CO 2 reduction reaction thanks to strong coupling, yield up 12.27 mmol g −1 h 90.6% selectivity under visible‐light irradiation. Density functional theory calculation experimental studies prove individual MOF not only directs expedites charge transfer within a catalyst particle but also creates catalytically‐active Ni sites for efficient photoreduction. current findings add growing literature materials compositional provide reference future research.
