Summary: Self-assembly is an efficient method for designing functional nanomaterials. In this study, a functional perylene diimide (PDI) derivative, PDI-DA, was designed to investigate the pathway complexity during self-assembly. The temperature control and UV-induced polymerization helped capture the intermediates and understand the mechanism. The morphological evolution showed two kinetic intermediates before transforming into the thermodynamic product, and spectroscopic studies revealed distinct H- and J-aggregates for kinetic and thermodynamic products respectively. The polymerized PDI-DA exhibited reversible switching between J- and H-aggregates.

Summary: Our study demonstrates the concept that single excitation of the two-electron reduced forms of perylene diimides (PDIs) with green photons can produce excited states with similar or greater reducing power than the shorter-lived excited states of PDI radical monoanions. By performing multi-electron reduction of a photocatalyst with a sacrificial reagent before irradiation with low-energy photons, we can generate highly reactive excited states for photocatalytic reactions.

Summary: The current energy shortage is concerning and nuclear energy is crucial for the energy transition. Uranium, an important resource for the nuclear industry, is abundant in seawater. However, extracting uranium from seawater efficiently is challenging due to low uranium concentrations and biofouling. In this study, a 2D-perylene diimide-polyethyleneimine (PDI-PEI) photocatalyst was successfully synthesized to enhance uranium extraction. The photocatalyst creates an electric field on its surface, attracting and adsorbing uranium from seawater. It also has antibacterial activity and hydrophilicity, making it a versatile method for uranium adsorption.

Summary: In this study, a novel MOF photocatalyst is constructed by encapsulating C-60 into a nano-sized zirconium-based MOF, NU-901, resulting in a substantial electrostatic potential difference and a robust built-in electric field. The photocatalytic hydrogen evolution rate for C-60@NU-901 reaches 22.3 mmol g(-1) h(-1), which is among the highest values for MOFs. Harnessing host-guest interactions to enhance charge separation is a promising strategy for designing efficient photocatalysts for solar-to-chemical energy conversion.

Summary: A series of 3D ordered macroporous (3DOM) Bi4O5Br2 photocatalysts with different macropore sizes were fabricated using a PMMA template method. The photocatalytic activity of 3DOM Bi4O5Br2 first increased and then decreased with the rise in macropore size. Specifically, 3DOM Bi4O5Br2-255 exhibited the highest photocatalytic activity among various catalysts tested, showing significantly higher efficiency in phenol degradation compared to bulk Bi4O5Br2, Bi2WO6, and g-C3N4. The improved performance of 3DOM Bi4O5Br2-255 can be attributed to its enhanced phenol adsorption, O2 activation, and charge separation and transfer abilities.

Summary: In this study, highly crystalline BiOI nanosheets with I-rich surface were used to enhance the intensity of the internal electric field (IEF) and direct charge migration. The I-rich BiOI demonstrated a 62.5-fold improvement in IEF intensity compared to I-poor BiOI due to its well-developed crystalline structure, and its IEF direction was reversed by the surface I-rich layers. This intensified IEF induced efficient charge separation and enhanced photocatalytic activity. The manipulation of IEF through surface and bulk structure regulation of BiOI offers a promising approach to improve photocatalytic performance.

Summary: This study reports an effective strategy to enhance the nitrate electroreduction (NO3ER) activity by tuning the A-site deficiencies of cobalt-based perovskite oxides. The NO3ER activity of (Ba0.5Sr0.5)(1-x)Co0.8Fe0.2O3-d (x = 0, 0.05, 0.10, 0.15, and 0.20) catalysts shows a volcano-type dependence on the x values, with the maximum point at x = 0.15. Among them, (BS)(0.85)CF exhibits the highest activity (143.3 mg h(-1) mg(cat)(-1) or 0.86 mmol h(-1) cm(-2)) and selectivity (97.9%) for ammonia, with excellent stability (200 h), surpassing most reported NO3ER catalysts. The optimized NO3ER properties are attributed to the modulation of physicochemical properties by A-site deficiencies, such as the creation of a moderate amount of oxygen vacancies and the introduction of a moderate distance between the band center and Fermi level. This work provides a new avenue for designing advanced cobalt-based perovskite oxides for NO3ER catalysis.

Summary: Interface Pt-O bonded Pt-Ov-BiOBr catalysts were designed for photocatalytic selective oxidation of 5-hydroxymethylfurfural (HMF). The Pt-O bond on the unsaturated coordination environment of Ov-BiOBr serves as an electron transport channel to efficiently generate O-2(-). Photogenerated h(+) gathers at the Pt-Ov-BiOBr interface to oxidize HMF to carbon-centered radicals. The spatial proximity of O-2(-) and carbon-centered radicals at the Pt-Ov-BiOBr interface promotes reciprocal collisions and reactions, enhancing the efficiency of HMF photocatalytic selective oxidation.
