Abstract The rational design of a photocatalyst and its microenvironmental modulation is crucial in the heterogeneous photocatalysis process, yet relevant research on photocatalytic biodiesel synthesis not explored. Herein, based prediction density functional theory (DFT) calculations, highly efficient ternary biocompatible montmorillonite (Mt) nanocomposites S‐scheme heterojunction photocatalysts (g‐C 3 N 4 ‐TiO 2 @Mt, CTM) are successfully rationally designed. By modulating microenvironment production, CTM‐2 demonstrates exceptional catalytic performance stability, achieving record‐breaking yield 98.5%. Through ex/in situ X‐ray photoelectron spectroscopy (XPS), absorption near‐edge (XANES), theoretical formation revealed, which can generate an interface electric field (IEF) that provides intrinsic driving force for carrier migration enhances surface positivity. This boosts enrichment effect electronegative oleic acid (OA) carboxyl molecules, thus greatly enriching substrate concentration improving reaction microenvironment. Moreover, fourier transform infrared spectrometer (FT‐IR)/Raman together with electron paramagnetic resonance (EPR) further confirm key intermediates CH O• ester carbonyl (C═O), DFT calculations provide reference pathway, determined to be capable significantly reducing energy barrier rate‐determining step.

Abstract Floaters with exposed surfaces are essential for applications in heterogeneous catalysis, microdetectors, and solar evaporation. Conventional floaters, however, rely on specific low‐density or hydrophobic materials, restricting their adaptability. This study introduces a topological design principle, enabling dense, hydrophilic materials to float stably water. The proposed cellular sheet (HCS) features water‐attractive substrate patterned crown‐shaped pore array, fabricated via digital light processing. These unique pores trap air effectively, providing exceptional buoyancy. modular of the HCS allows versatile plug‐in functionalities by utilizing as reservoirs functional beads. combination multi‐HCSs enables on‐water information encryption decryption. Furthermore, demonstrates potential supporting devices triboelectric nanogenerators, promising wave energy harvesting. work establishes platform designing adaptable floaters integrated functionalities, expanding utility areas, such interface carriers, devices, renewable collection.

Abstract The excessive release of CO 2 from fossil fuel combustion has disrupted the carbon cycle, leading to elevated greenhouse gas levels. Converting into value‐added chemicals like CH 4 and C H not only offers a sustainable alternative fuels but also helps mitigate emissions. However, producing high‐energy hydrocarbons involves complex electron proton coupling, presenting significant kinetic challenges. Photothermal catalysis, which harnesses solar energy in light heat, emerges as promising method for efficient conversion hydrocarbons. This process reduces thermodynamic barriers protonation by enabling rapid transfer through thermal assistance. development photothermal catalysts capable absorbing light, generating electron–hole pairs, facilitating redox reactions is crucial enhancing efficiency selectivity. review highlights importance catalyst design, reaction conditions, reactor configuration, addresses lack comprehensive reviews on synergistic approach catalysis. By focusing precise design photogenerated heat mechanisms, this aims advance field, emphasizing its potential promote carbon‐neutral future.

Abstract Poor light absorption, recombination of photogenerated charges, low surface area, and insufficient catalytically active sites are the most studied conventional bottlenecks photocatalysis processes, which hinder efficiency photocatalytic materials. However, there other less factors such as solubility diffusion reactants in reaction system, also responsible for sluggish kinetics can alter selectivity. The diphase reactions at liquid–solid interface suffer from poor slow transport a medium. emerging triphase photocatalysis, occurs gas–liquid‐solid liquid–liquid–solid has shown potential addressing these less‐studied issues achieved better performance than reactions. This review article mainly focuses on understanding mechanism basic difference between along with requirements photocatalysis. Several examples including CO 2 reduction, N fixation, H O production, organic pollutant degradation discussed detail this review. Finally, summary future directions field provided to guide researchers design remarkable systems excellent efficiencies.
