Considering the wide visible light absorption of perylene diimide (PDI) molecules, gold nanorods (AuNRs) can be utilized by matching their transversal and longitudinal surface plasmon resonance (SPR) bands with the absorption wavelengths of PDI-based photocatalysts to achieve an efficient enhancement of the catalytic activity. Herein, the composite photocatalyst of AuNRs-decorated self-assembled PDI nanowires (s-PDI/AuNRs) has been successfully prepared and further applied in the self-powered photoelectrochemical cell as the anode to supply H2O2 fuel. The s-PDI/AuNRs-based cell displays a maximum power density of 2.36 mW cm–2 in 0.1 M HCl electrolyte, which has 65.0% and 31.8% enhancement compared to the pristine PDI-based cell (1.43 mW cm–2) and the s-PDI-based cell (1.79 mW cm–2), respectively. Moreover, the photocatalytically produced H2O2 can be stored under light, which is then used as a fuel for cell operation in darkness. The specific capacitance can be achieved as high as 43.1 F cm–2, retaining 52.6% of its initial value after 12 h. It is verified that the enhanced photocatalytic performance of s-PDI nanowires can be ascribed to the specific intermolecular π-π stacking caused by the introduction of terminal carboxyl groups, which results in the deepening of the valence bandwidth and the enhancement of hole oxidation capacity.

Geological Culture Villages Towns (GCV(T)s) serve as rich repositories of geological resources, embodying significant historical and cultural values that mirror the dynamic interplay between Earth's evolution and human societies. Despite their importance, the theoretical underpinnings of GCV(T)s have not been thoroughly explored and elucidated. This study explores the relationship between geological culture and societal development, revealing the linkage between geological culture and societal advancement with the aim of promoting a harmonious coexistence between humanity and the environment. Focusing on 96 GCV(T)s in China, this study employs spatial analytical techniques such as the nearest-neighbor index, kernel density analysis, geographic connectivity, and geographic detector to scrutinize the spatial distribution patterns and identify key influencing factors. The findings reveal that (1) GCV(T)s exhibit uneven distribution, with concentrations in the Yangtze River Delta region, Beijing-Tianjin-Hebei region, and Shanxi-Gansu and Ningxia Provinces. (2) These sites tend to be situated in areas characterized by active geological formations, abundant geological relics, higher elevations, gentle topography, and ample rainfall. (3) The establishment and evolution of GCV(T)s are shaped by a complex interplay of geological heritage, natural factors, and human interventions. While the selection and spatial arrangement of these sites are predominantly influenced by geological and natural factors, the innovative development of their geological cultural heritage is driven by humanistic considerations. Overall, the distribution and evolution of GCV(T)s stem from multifaceted interactions among diverse factors. Recognizing this intricate web of influences is crucial for safeguarding geocultural diversity and formulating conservation strategies for geoheritage protection. The development of GCV(T)s transcends mere geoheritage preservation, it embodies a pivotal stride toward safeguarding the varied and multi-dimensional global geoheritage. [ABSTRACT FROM AUTHOR]

A type of photocatalytic agent graphitic carbon nitride (g‐C3N4) has been formed by the thermal polymerization of urea with citric acid, with various contents of C in its material (CN‐x). Through the characterization of its morphology, structure, chemical composition, and photoelectric properties, it is found that the introduction of C dopant enhances sunlight absorption and facilitates electron‐hole separation and charge transfer within the g‐C3N4 structure. By further optimizing the doping amount of C, the photocatalytic degradation rates of CN‐10 on Rh B, methylene blue and amaranth reached 97.2 %, 94.2 %, and 91.2 % within 40 min, which were 1.1 times, 1.3 times, and 2 times of the unmodified g‐C3N4, respectively. Sacrifice experiments showed that ⋅O2− and ⋅OH were the main active substances in the photocatalytic degradation of Rh B and amaranth. In the degradation of methylene blue, ⋅O2− and h+ were then the main active substances. [ABSTRACT FROM AUTHOR]
