Developing low-cost bifunctional electrocatalysts is key to achieving overall water electrocatalytic decomposition. The reported cobalt-doped Ni10Mo/MoO2 (Co─Ni10Mo/MoO2) catalyst exhibits outstanding bifunctional activity for hydrogen evolution reaction (HER) and oxygen evolution reaction (OER) in alkaline media. The overpotentials for HER at 10 and 100 mA cm-2 are 42 and 168 mV, respectively, while OER overpotentials were 273 and 328 mV, respectively. This catalyst eliminates the traditional two-step process of hydrothermal + high-temperature calcination, dispensing with the hydrothermal pretreatment step. While maintaining catalytic performance, it simplifies the preparation process and optimizes costs, offering a more viable technical pathway for clean hydrogen production. Only 1.49 V and 1.55 V voltages are required to reach a current density of 10 mA cm-2 in overall alkaline water and alkaline seawater splitting, respectively. Furthermore, this Co─Ni10Mo/MoO2 catalyst demonstrates long-term stability for up to 1200 h during overall alkaline seawater splitting. Moreover, in practical applications, a solar panel can drive this highly efficient overall water-splitting process, demonstrating its capability to store solar energy in the form of O2 and H2.","PeriodicalId":144,"journal":{"name":"Chemistry - A European Journal","volume":" ","pages":"e71071"},"PeriodicalIF":3.7,"publicationDate":"2026-04-27","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"147758212","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":2,"RegionCategory":"化学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

However, conventional one-step photoexcitation systems impose stringent thermodynamic constraints on the band structure of photocatalysts, severely limiting the number of materials that can simultaneously exhibit visible-light absorption and high catalytic efficiency. In contrast, the Z-scheme overall water splitting substantially mitigates these thermodynamic demands, thereby enabling the utilization of a wider spectrum of visible-light-responsive semiconductors. Among the semiconductor materials investigated, (oxy)nitrides have attracted significant attention as ideal candidates for Z-scheme systems, owing to their tunable electronic structures, strong visible-light absorption, and favorable band edge positions. Nevertheless, issues such as photocorrosion, high defect densities, and sluggish surface reaction kinetics continue to hinder their catalytic performance. This review comprehensively summarizes recent advances in three types of Z-scheme overall water splitting systems based on (oxy)nitride photocatalysts: redox couple-based ionic Z-schemes, solid-mediator Z-schemes, and direct Z-schemes. It focuses on the material design strategies and the structure-performance relationships of (oxy)nitrides within these distinct Z-scheme systems. Finally, the challenges and future prospects of (oxy)nitride-based Z-scheme overall water splitting systems are discussed, offering insights into the optimization of material synthesis, surface modification, and mechanistic understanding.","PeriodicalId":144,"journal":{"name":"Chemistry - A European Journal","volume":" ","pages":"e03297"},"PeriodicalIF":3.7,"publicationDate":"2026-04-25","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"146148593","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":2,"RegionCategory":"化学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

This method generates various C-centered radicals, including methyl and acyl radicals, which undergo subsequent C─C bond-forming reactions. Density functional theory (DFT) calculations suggest that the selectivity of C─C bond cleavage can be predicted according to the relative thermodynamic favorability among competing β-scission pathways. Competition experiments showed that the β-scission of a 3° alcohol is suppressed in the presence of a carboxylic acid, where then decarboxylation of the carboxylic acid predominates. These results were attributed to the less favorable adsorption of the 3° alcohol on TiO2 relative to that of the carboxylic acid. By leveraging the adsorption-controlled reaction kinetics, a synthetic strategy involving decarboxylation, and subsequent β-scission was developed, which enabled the sequential incorporation of two different components into a substrate that contains a carboxylic acid and a 3° alcohol moiety. This work thus showcases the unique reactivity and selectivity of the Pt/TiO2-photocatalyzed β-scission of 3° alcohols, offering a new and distinctive addition to the toolkit of the modern organic chemist (186/200).","PeriodicalId":144,"journal":{"name":"Chemistry - A European Journal","volume":" ","pages":"e03629"},"PeriodicalIF":3.7,"publicationDate":"2026-04-25","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://www.ncbi.nlm.nih.gov/pmc/articles/PMC13109682/pdf/","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"147281384","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":2,"RegionCategory":"化学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"OA","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

However, conventional porous carbons often suffer from limited capacity and unsatisfactory rate capability due to insufficient active sites, mismatched pores, and low nitrogen-doping levels. Herein, we propose a novel strategy for synthesizing nitrogen-doped porous carbon (NPC) with a hierarchical pore structure using graphitic carbon nitride (g-C3N4) as a dual-function soft template and nitrogen source and potassium citrate as a combined carbon precursor and activating agent. The optimal material, NPC-0.5 (with a g-C3N4/potassium citrate mass ratio of 1:3), exhibits a high specific surface area (805 m2 g-1), a well-defined hierarchical pore network, and a nitrogen content of 7.94 at% dominated by graphitic-N species, which collectively enhance Zn2+ storage and facilitate rapid ion transport. When employed as a cathode for ZIHCs, the NPC-0.5 delivers a high specific capacity of 172 mAh g-1 at 0.1 A g-1, excellent rate capability (41% capacity retention at 20 A g-1), and outstanding long-term cycling stability (86% capacity retention after 65,000 cycles at 10 A g-1).

Among these, the addition of radicals onto the carbon centers of olefins is the common key step in two distinct synthetic approaches: the P-H addition reactions catalyzed by radical additives, as well as the radical-induced polymerization. To gain a comprehensive understanding of reactivity trends, we explored computationally how the chemical nature of radicals affects the thermodynamics and kinetics of their reaction toward the parent ethylene and a set of variously substituted olefins. As a result, the fundamental differences between the main types of phosphinyl and phosphonyl radicals have been clarified. In general, the reaction energies of additions correlate with the radical stabilization energies obtained for the attacking radical: Less stable radicals lead to more exothermic reactions, and their reactions are also characterized by lower activation barriers. Consequently, the relative reactivity of a P-centered radical, in terms of both kinetic and thermodynamic parameters of the addition, can be well predicted using the easily accessible radical stabilization energies prior to experiments. The predictive value of this methodology was verified using explicitly calculated energies on a set of radicals suitable for experimental investigations.","PeriodicalId":144,"journal":{"name":"Chemistry - A European Journal","volume":" ","pages":"e70726"},"PeriodicalIF":3.7,"publicationDate":"2026-04-25","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://www.ncbi.nlm.nih.gov/pmc/articles/PMC13109694/pdf/","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"146163212","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":2,"RegionCategory":"化学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"OA","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
