Abstract A novel phthalocyanine‐based hybrid nanofilm is for the first time successfully applied as an oxidative platform surface enhanced Raman spectroscopy (SERS) sensing to fine‐resolve Raman‐inactive compounds. The formed by self‐assembly of zinc(II) 2,3,9,10,16,17,23,24‐Octa[(3′,5′‐dicarboxy)‐phenoxy]phthalocyaninate (ZnPc*) with solid‐supported monolayer graphene oxide (GO) mediated zinc acetate metal cluster. Atomic force microscopy, UV–vis and fluorescence spectroscopies confirm that this simple coordination motive in combination molecular structure ZnPc* prevents contact quenching light‐excited triplet state through aromatic stacking GO particles. Fluorescence probing Sensor Green terephthalic acid specific indicators active oxygen intermediates shows initiates selective singlet generation under visible light. Direct one‐electron oxidation tetramethylbenzidine (TMB) (1.0×10 −7 m ) on presence 100 nm silver nanoparticles plasmonic hot‐spots 450–640‐nm light irradiation yields well‐resolved resonance spectrum oxidized form TMB +1 . Using these nanofilms platforms redox reaction target analytes without additional oxidizing agents, range Raman‐detectable compounds can be significantly expanded a rapid ultrasensitive SERS screening substances currently considered Raman‐inactive.

This study addresses the critical need for efficient and recyclable photocatalysts water treatment applications by presenting a novel approach synthesis characterization of copper (I) oxide (Cu2O) nanoparticles modified with ascorbic acid (Cu2O/AA). The motivation this research stems from increasing concern about environmental pollution caused organic pollutants, such as Brilliant Cresyl Blue (BCB), necessity sustainable solutions to mitigate issue. Through comprehensive techniques including Ultraviolet–Visible spectroscopy (UV-Vis), Fourier Transform Infrared (FTIR), X-ray Diffraction (XRD), Scanning Electron Microscopy (SEM), zeta potential measurements, Brunauer–Emmett–Teller (BET) analysis, we demonstrate significant modification electronic structure, enhancing photocatalytic activity Cu2O/AA. BET analysis revealed mesoporous structure specific surface area 2.7247 m2/g Cu2O/AA, further emphasizing its enhanced catalytic performance. degradation studies showcased remarkable efficiency improvements, coefficients 30.8% 73.12% Cu2O NPs Cu2O/AA NC, respectively, within 120 min timeframe. Additionally, recyclability experiments indicated sustained over five consecutive cycles, both catalysts retaining crystalline integrity. These findings underscore promising highly offering superior performance compared pure addressing pressing solutions.
