However, conventional single-material photocatalysts struggle to fulfill the stringent criteria of high efficiency, stability, cost-effectiveness, and responsiveness to visible light. The elevated recombination rates of photogenerated charge carriers, coupled with the suboptimal utilization of visible light, have collectively constrained the photocatalytic and photoelectrocatalytic H<sub>2</sub>O<sub>2</sub> production. Heterojunction catalysts for the production of H<sub>2</sub>O<sub>2</sub> has become a focal point of research. This review commences by elucidating the fundaments underlying the photocatalytic and photoelectrocatalytic H<sub>2</sub>O<sub>2</sub> production. Subsequently, it delineates the distinctive electron transfer mechanisms of Z-scheme and S-scheme heterojunctions, which exhibit enhanced efficiency in the photocatalytic and photoelectrocatalytic H<sub>2</sub>O<sub>2</sub> production, along with a summary of strategies for the improvement of photocatalyst and photoelectrocatalyst performance. Furthermore, this review also outlines the latest fabrication strategies, state-of-the-art <em>in-situ</em> characterization techniques, machine learning and density functional theory (DFT) simulations for Z-scheme or S-scheme catalysts for the photocatalytic and photoelectrocatalytic H<sub>2</sub>O<sub>2</sub> production, and briefly describes the multifunctional applications in H<sub>2</sub>O<sub>2</sub> production. Ultimately, the review contemplates the prospective developmental trajectories and application potential of these heterojunction configurations for the photocatalytic and photoelectrocatalytic H<sub>2</sub>O<sub>2</sub> production.</div></div>","PeriodicalId":10088,"journal":{"name":"Chinese Chemical Letters","volume":"36 10","pages":"Article 111418"},"PeriodicalIF":9.4,"publicationDate":"2025-06-07","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"144663058","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":1,"RegionCategory":"化学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

While trace metal interference in as-synthesized catalysts has been ruled out, the impact of trace metal contamination during electrochemical activation remains unexplored. This study demonstrates that anodic pretreatment in alkaline electrolytes enhances the catalytic performance of carbon cloth. Specifically, carbon cloth activated in 8 mol/L NaOH achieves a current density of 10 mA/cm<sup>2</sup> with an overpotential of only 338 mV, comparable to metal-based OER catalysts. Electrochemical and spectroscopic analyses show the deposition of FeNiO<sub>x</sub>H<sub>y</sub> oxyhydroxides (0.19 ± 0.06 µg/cm<sup>2</sup>) on specific sites of the carbon substrate during activation. These nanoparticles contribute significantly to the catalytic activity, with a synergistic effect between FeNiO<sub>x</sub>H<sub>y</sub> and the carbon substrate. The turnover frequency (TOF) for Fe correlates with the amount of C=O groups on the carbon substrate, providing evidence for an interfacial synergistic effect. This work emphasizes the importance of considering trace metal effects in metal-free catalyst evaluation and offers insights for the design of more efficient carbon-based hybrid OER catalysts.</div></div>","PeriodicalId":10088,"journal":{"name":"Chinese Chemical Letters","volume":"36 11","pages":"Article 111417"},"PeriodicalIF":8.9,"publicationDate":"2025-06-06","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"144865988","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":1,"RegionCategory":"化学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Graphene-based water treatment materials show significant advantages in wastewater treatment. However, with the development of graphene-based materials, its progress in water treatment has reached a bottleneck. The challenge lies in effectively enhancing its performance in water treatment and ensuring its practicality. By employing biomimetic approaches, some exceptional properties and structures found in nature can be mimicked in graphene materials, effectively enhancing graphene's adsorption and mechanical properties. Current biomimetic methods include biomimetic mineralization, self-assembly, and templating. unfortunately, all of the above methods suffer from the disadvantages of complexity and poor bionic effect. Nevertheless, 3D printing, a form of additive manufacturing (AM) technology, offers integrated molding and excellent biomimetic performance in creating biomimetic materials. This paper will cover the following aspects: (1) An overview of objects suitable for bionics in terms of functional and structural aspects, along with their properties, and a discussion of various bionic objects combined with graphene materials in water treatment and related research; (2) a comparison of different methods for preparing graphene-based bionic materials; (3) an examination of the current drawbacks and limitations of graphene-based biomimetic materials; and (4) a conclusion and future prospects, exploring the potential of using 3D printing technology to produce graphene biomimetic materials.

However, safety concerns related to lithium dendrite-induced short circuits and suboptimal electrochemical performance have impeded the commercial viability of lithium metal batteries. Current research efforts primarily focus on altering the solvated structure of Li<sup>+</sup> by modifying the current collector or introducing electrolyte additives to lower the nucleation barrier, expedite the desolvation process, and suppress the growth of lithium dendrites. Nevertheless, an integrated approach that combines the advantages of these two strategies remains elusive. In this study, we successfully employed metal-organic salt additives with lithophilic properties to accelerate the desolvation process, reduce the nucleation barrier of Li<sup>+</sup>, and modulate its solvated structure. This approach enhanced the inorganic compound content in the solid electrolyte interphase (SEI) on lithium foil surfaces, leading to stable Li<sup>+</sup> deposition and stripping.
