In this work, a series of novel bromo-p-hydroxybenzamides were designed based on the molecular hybridization strategy, and rapidly synthesized by one-step amidation reaction, and then characterized by 1H NMR, 13C NMR and HRMS. The herbicidal activity assay indicated that most of the target compounds exhibited good-to-excellent inhibition effects on seed germination of two model plants. At a concentration of 100 mg/L, the inhibition rate of 3,5-dibromo-N-(4-bromo-3-chlorophenyl)-p-hydroxybenzamide reached up to 98 and 96% on the roots and stalks of the monocotyledonous barnyard grass (E. crus-galli), respectively. 3,5-Dibromo-N-(2-bromophenyl)-p-hydroxybenzamide showed excellent inhibitory activity on the roots and stalks of dicotyledonous rape (B. napus) at 100 mg/L, with an inhibitory rate of more than 90%. Furthermore, the concentration was reduced to 1 mg/L, the inhibitory rate of 3,5-dibromo-N-(2-bromophenyl)-p-hydroxybenzamide on the roots of B. napus was still as high as 90%. This work provides a novel molecular scaffold for the development and research of new super-efficient herbicides.","PeriodicalId":761,"journal":{"name":"Russian Journal of General Chemistry","volume":"95 3","pages":"644 - 653"},"PeriodicalIF":0.9,"publicationDate":"2025-03-27","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143716665","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":4,"RegionCategory":"化学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

This study presents a straightforward approach to integrating CuCo2O4 with BiVO4 to form a p–n junction, substantially enhancing the separation of electron-hole pairs on electrode surfaces. The photoelectrode BiVO4/CuCo2O4, which was prepared with an optimal CuCo2O4 loading, achieved a significant photocurrent density of 1.26 mA/cm2 at a potential of 1.23 V relative to the reversible hydrogen electrode (RHE). Experimental investigations confirmed that the presence of CuCo2O4 enhances the mobility and separation of photogenerated electron-hole pairs. The outstanding performance in PEC water splitting demonstrated by the CuCo2O4/BiVO4 composite electrode suggests its excellent suitability for applications involving solar-assisted water splitting.","PeriodicalId":761,"journal":{"name":"Russian Journal of General Chemistry","volume":"95 3","pages":"572 - 579"},"PeriodicalIF":0.9,"publicationDate":"2025-03-27","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143716668","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":4,"RegionCategory":"化学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

This work prepared biochar modified by zinc and manganese (Zn/Mn–BC) through straightforward impregnation pyrolysis for the removal of oxytetracycline from wastewater. Characterizations, adsorption performance, reusability, and mechanisms were studied. Results showed that the Zn/Mn–BC had the highest OTC adsorption capacity (60.81 mg/g) and exhibited finer separation performance at low OTC concentrations. Notably, Zn/Mn–BC can keep a high removal rate (75.86%) of OTC after 5 cycles. The kinetic and isotherm models reveal that the adsorption process is multi-layer chemisorption. Thermodynamic data indicates that OTC adsorption by Zn/Mn–BC is an exothermic, spontaneous process with decreasing entropy. In addition, the possible mechanisms of adsorption are mainly electrostatic, hydrogen bonds, π–π stacking interactions, and especially metal oxide bonds (M–O) for OTC removal. This study not only realizes the strategy of turning waste into a treasure of chestnut shell but also provides an alternative and sustainable adsorbent for antibiotics from wastewater.","PeriodicalId":761,"journal":{"name":"Russian Journal of General Chemistry","volume":"95 3","pages":"580 - 592"},"PeriodicalIF":0.9,"publicationDate":"2025-03-27","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143716927","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":4,"RegionCategory":"化学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

The reaction product was examined using 1H, 13C NMR and IR spectroscopy methods, in addition to ultra-performance liquid chromatography (UPLC). Moreover, the reaction was monitored spectrophotometrically, with (0.1–0.4) × 10–4 mol/dm3 of Bac, (0.5–5.0) × 10–2 mol/dm3 Van and 0.2–1.0 mol/dm3 ionic strength (I) over the temperature range of 40–60°C. The reaction is first order with respect to [Van] and [Bac], and the rate of the reaction decreases as pH increases in the range of 3.60–4.66. In addition, the effect of catalyst on the rate of the reaction was studied, and the thermodynamics activation parameters involving ∆H* and ∆S* were calculated. The rate of the reaction obeys the rate law d[Bac–Van]/dt = {k2 + (k4 + k3[H+])[Van]} × [Bac]. This experimental rate law is consistent with a mechanism in which both the protonated and unprotonated forms of Van are involved in the rate-determining step, with the protonated species being the more reactive form. Furthermore, density functional theory (DFT) was performed to search the geometries of the final product resulting from the reaction between Bac and Van. Finally, interaction region indicator (IRI) calculations were used to reveal chemical bonding and weak interaction in the coupled compound Bac–Van.","PeriodicalId":761,"journal":{"name":"Russian Journal of General Chemistry","volume":"95 3","pages":"620 - 629"},"PeriodicalIF":0.9,"publicationDate":"2025-03-27","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143716930","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":4,"RegionCategory":"化学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
