“…Pd/Au@g-C 3 N 4 /TiO 2 photocatalysts exhibit superior activity to all catalysts in the series due to heterojunction formation and dual-metal (Pd/Au) loading. Pd/Au@g-C 3 N 4 /TiO 2 exhibited E g at 2.95 eV, which falls between the E g value of g-C 3 N 4 (2.67 eV) and TiO 2 (3.05 eV), as represented in Figure b. Moreover, Pd formed the Schottky junction with the semiconductor (g-C 3 N 4 /TiO 2 ) while the Au nanoparticles provided a surface plasmon resonance effect to facilitate the excited e – to the redox center.…”

The ecological impact and rising expenses of fossil fuels have led researchers to investigate alternative renewableenergy sources. Current work reported a novel and sustainable water splitting system comprising TiO 2 /Pd/Au integrated on g-C 3 N 4 surfaces. The phase purity and crystallization were analyzed by XRD, revealing characteristic patterns of TiO 2 , g-C 3 N 4 , and loaded Pd−Au cocatalysts. The electronic and structural properties were analyzed by Raman spectroscopy. The efficient charge separation in Pd/Au@g-C 3 N 4 /TiO 2 was demonstrated by PL spectral and TRPL analyses. Interface analysis, charge transfer resistance/capacitance, and dynamics were evaluated by EIS and temporal photocurrent responses. FTIR spectra indicate the interfacial connection between g-C 3 N 4 /TiO 2 , while UV−vis/DRS revealed that Pd/Au@g-C 3 N 4 /TiO 2 exhibited superior optical absorption (absorption edge at 457 nm). The BET technique confirmed the mesoporous nature of Pd/Au@g-C 3 N 4 /TiO 2 , while SEM demonstrated its lumpy surface morphology with high dispersion of cocatalysts. The elemental compositions and electronic states were further confirmed by EDX and XPS. Hydrogen evolution activities were conducted in the sunlight using a GC equipped with TCD. Activities indicated an encouraging rate of H 2 generation on fabricated g-C 3 N 4 /TiO 2 heterojunctions (Z-scheme interaction) having a Au-LSPR effect along with a Pd Schottky barrier impact. The maximum H 2 evolution rate of 36.51 mmol g −1 h −1

Synergistic engineering of energy band alignment and interfacial electric field distribution is essential for photocatalyst design but is still challenging because of the limitation on refined regulation in the nanoscale. This study addresses the issue by employing surface modification and thermal-induced phase transformation in Bi2MoO6/Bi x O y I z hetero-nanofiber frameworks. The energy band alignment switches from a type-II interface to a Z-scheme contact with stronger redox potentials and inhibited electron traps, and the optimized built-in electric field distribution could be reached based on experimental and theoretical investigations. The engineered hetero-nanofibers exhibit outstanding visible-light-driven photocatalytic nitrogen reduction activity (605 μmol/g/h) and tetracycline hydrochloride removal rate (81.5% within 30 min), ranking them among the top-performing bismuth series materials. Furthermore, the photocatalysts show promise in activating advanced oxidants for efficient organic pollutant degradation. Moreover, the Bi2MoO6/Bi5O7I hetero-nanofibers possess good recycling stability owing to their three-dimensional network structure. This research offers valuable insights into heterojunction design for environmental remediation and industrial applications.
