Driven by the urgent need for eco-friendly, safe and facile production processes for hydrogen peroxide (H 2 O 2 ), piezocatalysis shows significant potential due to its accessible energy supply and capacity for on-site H 2 O 2 preparation. Owing to their tunable surface properties and unique electronic structures, transition metal dichalcogenides (TMDCs) are regarded as promising piezocatalysts. Nevertheless, the uneven distribution of active sites, poor stability, and restricted electron transport capabilities hinder the further improvement of their piezocatalytic performance. In this study, WS 2 thin sheets were prepared by liquid-phase stripping, which significantly increase the number of exposed active sites to provide an optimized interfacial environment for the adsorption of reactant molecules, and the resulting thin-layer structure greatly improves the charge transfer efficiency. More importantly, WS 2 thin sheets were utilized in piezocatalytic H 2 O 2 evolution. Remarkably, under conditions of pure water and ambient air, these thin sheets exhibit outstanding piezocatalytic performance with an H 2 O 2 evolution rate as high as 994.7 μmol g −1 h −1 . And they retained 80.14 % of their activity after 10 h of cyclic operation, demonstrating excellent cycling stability. Furthermore, mechanistic investigations propose three potential pathways for H 2 O 2 evolution, providing a novel perspective for elucidating the underlying mechanism of piezocatalysis in TMDCs.

Magnetic nano-detection systems for monitoring symptoms subsequent to cancer treatment have drawn significant attention within the domain of therapeutic diagnostics. However, the weak affinity of target analytes with traditional magnetic SERS substrate and complex matrix interference impede the achievement of high sensitivity and precision necessary for practical H 2 O 2 applications. Herein, Based on Fe 3 O 4 @SiO 2 @Au seed-MBN (4-mercaptobenzoonitrile) @Au (FSAMA) substrate and the electro-driven adsorption strategy, this study develops a SERS sensor for quantification of H 2 O 2 residue. The magnetic core can improve cytocompatibility and reduce cytotoxicity with the inorganic SiO 2 layer. Au@DTNB (5,5'-Dithiobis-(2-nitrobenzoic acid)) @Ag molecules can be adsorbed onto the “hotspot” region of FSAMA substrate to obtain enhanced SERS signals. Though the enhanced second-harmonic generation (SHG) effect, the H 2 O 2 oxidizes the Ag layer of FSAMA-Au@DTNB@Ag to Ag (I), which will significantly cause changes the SERS signal, which is improved by 2-3 orders of magnitude. The incorporation of inner-layer labeling molecules within the Au NPs enhances the stability of SERS signal output while maintaining excellent Raman signal contrast for H₂O₂ detection. In summary, the FSAMA-SERS sensing system developed for detecting H₂O₂ levels may serve as a promising platform for diagnostic and prognostic monitoring, applicable across a wide range of complex serum samples.

Nitrogen heterocyclic covalent organic frameworks offer great potential for H 2 O 2 production due to their unique optical and electrical properties. Herein, we design four photocatalysts with varying nitrogen atom configurations to tune their electronic and energy-band structures. Among them, the covalent organic frameworks with pyrimidine achieves an efficient H 2 O 2 production rate of 17014 μmol g −1 h −1 and a solar-to-chemical conversion efficiency of 1.84% in pure water without sacrificial agent or oxygen aeration. The theoretical calculation and experimental study confirm that it owns superior photoelectrochemical properties, oxygen reduction reaction activity, and the lowest reaction potential barrier, enabling dual channel H 2 O 2 production via 2e − oxygen reduction reaction and 4e − water oxidation reaction. To explore the application potential of the photocatalytic system, a panel reactor (20 × 20 cm) under natural sunlight demonstrates continuous H 2 O 2 generation for antibiotic degradation and long-lasting water disinfection. This work presents an advanced photocatalytic H 2 O 2 synthesis system with high efficiency and environmental remediation potential.

The simultaneous photocatalytic production of hydrogen peroxide (H 2 O 2 ) and hydrogen (H 2 ) from water has received widespread attention. However, the inherent inefficiencies in dynamic processes, such as sluggish charge separation or accumulation, pose substantial limitations to overall photocatalytic performance. Here, a manganese-assisted carbon nitride/carbon nanoribbons (CN/CT-Mn) heterojunction is developed via a straightforward thermal evaporation process. The optimized CN/CT-Mn photocatalyst demonstrates exceptional activity for concurrent H 2 O 2 and H 2 production under ambient conditions, achieving impressive yields of 104 and 720 μmol g −1 h −1 , respectively. The enhanced performance can be attributed to the enhanced charge separation and the regulation of electron reduction kinetics resulting from the construction of the heterojunction interface. Notably, the presence of Mn atoms introduces an additional impurity level, enabling precise control over the reduction selectivity of photogenerated electrons. Graphical Solar-driven dual production of H 2 and H 2 O 2 is achieved via an Mn-doped carbon nitride/nanoribbon heterojunction. The built-in electric field at the heterojunction interface directs electron transfer from CN to Mn-CT, while Mn atoms enhance proton adsorption, selectively boosting H 2 evolution.

Plasmonic nanostructures are a promising class of materials for solar-chemical conversion and trace substance detection. However, the low effective electron density, poor charge separation efficiency and the inability to tandem solar-chemical conversion and trace detection capabilities limit their further application. Here, we report a multicomponent plasmonic hybrid consisting of in situ reduced gold nanoparticles anchored at the hetero-interface of reduced graphene oxide/polyethyleneimine/graphitic carbon nitride electrostatically assembled layers as the plasmonic photocatalysts and surface-enhanced Raman scattering (SERS) hotspots. Experiments and theoretical calculations prove that the hybrid simultaneously optimizes three keys to photocatalysis: i) the generation of electrons via multiple pathways and the increase of the effective electron density, ii) the formation of a hetero-interface to lower the Schottky barrier and the synergistic plasma resonance to form an electric field to promote the charge separation, iii) the promotion of the substrate molecule adsorption and the reconfiguration of the gold nanoparticles. Thus, the hybrid achieves an H 2 O 2 production rate of 2.196 mmol g −1 h −1 in air and under acidic conditions. We further show that the complexes have synergistic effects in applications such as SERS detection of fruit and vegetable residues and photodegradation and antimicrobial preservation. This work may be useful for rationally designing plasmonic nanostructures and their application to photocatalysis in conjunction with SERS.

The photocatalytic production of hydrogen peroxide is a sustainable approach to producing oxygen and water. In this work, the microspheres flake-like, sheet-like, and flower-like BiOBr were by varying different solvents during the reaction process. The investigation revealed that the highest hydrogen peroxide production of 294 μmol g −1 h −1 was obtained for BiOBr(0 0 1). Their physico-chemical properties are fully investigated by XRD, SEM, XPS, ESR, and DFT calculation, which confirmed the exposure surface of BiOBr has a close relationship with the oxygen vacancy concentration, and BiOBr(0 0 1) has the highest oxygen vacancy concentration (oxygen vacancy formation energy 4.17 eV) and the best photocatalytic effect. DFT calculation also showed that the introduction of oxygen vacancies increased the adsorption and activation capacity of O 2 and greatly reduced the Gibbs free energy of the reaction pathway.

Production of H 2 O 2 via semiconductor photocatalysis has received an increasing attention. Herein the effects of cations in perchlorate form and anions in sodium form are examined. Experiment was conducted with Au/WO 3 under visible light in presence of methanol. The production of H 2 O 2 was greatly promoted by A (Ni 2+ , PO 4 3− , CO 3 2− , and F − ), slightly increased by B (SO 4 2− , NO 3 − , Cl − , and ClO 4 − ), greatly inhibited by C (Cu 2+ , and Fe 3+ ), and slightly decreased by Co 2+ . Moreover, the effect of Ni 2+ was weakening by F − , and vice versa. Analysis showed that Ni 2+ was oxidized into Ni 3+ , reactive to methanol, not to water. On Au/WO 3 electrode, anions A inhibited O 2 reduction, and promoted methanol photo-oxidation, while all anions had little influence on the pathway of O 2 reduction. A plausible mechanism is proposed, involving the hole oxidation of anions (not F − ), followed by methanol oxidation. This work highlights the importance of inorganic ions to the selective reduction of O 2 .

Hydrogen peroxide (H 2 O 2 ) photosynthesis from H 2 O and O 2 remains a significant challenge due to the sluggish hydrogen donation process, which stems from the high O–H bond dissociation energy of water. In this study, we propose an effective strategy to accelerate the water oxidation reaction (WOR) by anchoring single palladium atoms (Pd–CNO 2 ) onto a keto-anthraquinone covalent organic framework (KfAQ-Pd), achieving remarkable H 2 O 2 production rates of 3828 μmol h −1 g −1 under visible light irradiation ( λ > 420 nm) in neutral water. Both experimental observations and theoretical simulations reveal that the Pd–CNO 2 configuration induces an upward shift in the d-band center and enhances the hydrophilicity of KfAQ. This modification effectively disrupts the hydrogen-bond network within adsorbed water clusters, thereby promoting the cleavage of the dangling O–H bonds in H 2 O molecules and facilitating efficient hydrogen donation. The generated H 3 O + species are subsequently reduced in-situ by photogenerated electrons, leading to the hydrogenation of anthraquinone moieties and ultimately driving efficient H 2 O 2 photosynthesis. Overall, these findings highlight the pivotal role of single Pd atoms in enhancing water dissociation and hydrogen transfer, offering a promising new paradigm for solar-driven, environmentally friendly H 2 O 2 synthesis in neutral aqueous systems.

Reactive oxygen species (ROS)-induced DNA oxidative damage is a significant manifestation of oxidative stress in the body and is closely associated with the onset and progression of various diseases. Although Pyripyropene A (PPPA) exhibits anti-tumor and anti-inflammatory activities, its antioxidant and protective effects against DNA oxidative injury remain unclear. In this study, using a hydrogen peroxide-induced oxidative injury model of L02 cells, it was found that PPPA could significantly reduce intracellular ROS and malondialdehyde (MDA) levels, enhance the activities of catalase (CAT) and reduced glutathione (GSH), and increase the 2,2-Diphenyl-1-picrylhydrazyl (DPPH) clearance rate, confirming its antioxidant effect. Comet assay showed a reduction in DNA breakage, and down-regulation of phosphorylated histone (γ-H2AX) and 8-hydroxydeoxyguanosine (8-oxodG), indicating that it effectively alleviates DNA oxidative injury. Meanwhile, the upregulated expression of poly ADP-ribose polymerase (PARP) suggests that PPPA may promote repair by activating the DNA damage response (DDR). This study systematically clarify for the first time that PPPA exerts a protective effect by synergistically antioxidizing, reducing DNA injury, and potentially activating repair pathways, providing a theoretical basis for its application in neoplasm and oxidative stress-related diseases.

In this study, nitrilotriacetic acid (NTA) was used to enhance UV/Fe 0 /H 2 O 2 process for highly salty wastewater at neutral pH. The addition of Fe 0 could not accelerate the UV/H 2 O 2 process for salty wastewater treatment at neutral pH due to the precipitation of Fe ions. While NTA added into UV/Fe 0 /H 2 O 2 process which could form complex with Fe ion, the tartrazine removal could increase from 45.7% to 84.7% within 60 min. The k -value of the UV/Fe 0 -NTA/H 2 O 2 system to remove tartrazine is also 2.2 times higher than that in UV/Fe 0 /H 2 O 2 system. Meanwhile, the UV/Fe 0 -NTA/H 2 O 2 process could obtain good performance for salt wastewater treatment under a wide salt concentration level of 0–0.2 M. It can also expand the application range of pH to neutral pH. SEM and XPS characterization showed that the corrosion rate of Fe 0 in salty system was faster, and the presence of NTA could accelerate the recirculation of Fe 3+ /Fe 2+ on the Fe 0 surface. EPR spectroscopic analysis and scavenge experiments showed that • OH was the main reactive radical for the removal of tartrazine in the UV/Fe 0 -NTA/H 2 O 2 system. In addition, the k -value for removing tartrazine in various types of salt systems in the UV/Fe 0 -NTA/H 2 O 2 system was 3.2–4.2 times that of the UV/Fe 0 /H 2 O 2 system. It demonstrated UV/Fe 0 -NTA/H 2 O 2 processes fits to different types of salt system. Therefore, this study will provide a new method for the treatment of saline wastewater at neutral pH.

Photocatalytic oxygen reduction reaction (ORR) in seawater provides an efficient, cost-effective and sustainable pathway for hydrogen peroxide (H 2 O 2 ) production. However, developing the stable and high-efficiency seawater photocatalysts remains a crucial challenge due to the high concentration of Cl − and rapid charge carrier recombination rate. Here we fabricated 2D/2D CuS/CaIn 2 S 4 (CuS/CIS) heterostructured photocatalysts for visible-light-driven H 2 O 2 photosynthesis from seawater and O 2 under ambient condition. The introduction of CuS in CuS/CIS composites benefited superior light harvesting and the charge carrier separation. The optimized 5-CuS/CIS had an exceptional H 2 O 2 photosynthesis rate of 1194.0 μmol∙g −1 ∙h −1 with stable reusability in seawater, outperforming their counterparts. Additionally, 5-CuS/CIS possesses the higher H 2 O 2 photosynthesis rate in seawater and single salt-based solutions than that in deionized water. The corresponding enhancement mechanism of H 2 O 2 photosynthesis in seawater was discussed in depth. Thorough experimental analysis and theoretical calculations corroborate the two-step one-electron ORR path for H 2 O 2 photosynthesis. Through systematic characterization, we pinpoint the photo-reduction active sites governing H 2 O 2 formation and reveal optimized interfacial charge transfer pathways. This study offers new insights into designing stable heterostructured photocatalysts to facilitate charge carrier separation and achieve high-efficiency for H 2 O 2 photosynthesis from seawater.

Detection of H2O2 is important for the applications in environmental protection, pharmaceutical industries, food production, and clinical control. Current colorimetric assay of H2O2 based on enzyme or nanomaterials always needs TMB or other peroxidase substrate as coloration species. Furthermore, the corresponding response time including incubation process is in order of minute. In this study, we report on the synthesis of heavily Ti3+-doped TiO2 composed of spherelike nanoparticles by pulsed laser ablation method. This TiO2 can directly detect H2O2 without using TMB or any other peroxidase substrate and is free from incubation process. In addition, the detection sensitivity is compatible with or better than that of the natural enzyme or other nanomaterials. Hence, the self-doped TiO2 nanoparticles provide a novel, direct, ultrafast approach for H2O2 assay application.
