We present a simple, solvent-free, green solid-state reduction followed by oxidation (RFO) approach to obtain coral-like, interconnected α-Fe₂O₃ morphology with effective carbon doping. The readily available [Fe(acac)₃] coordination compound is directly subjected to this RFO process to yield carbon-doped α-Fe₂O₃ NPs. Effective in situ carbon doping in the α-Fe₂O₃ network is achieved using the single-source [Fe(acac)₃] complex, without employing any aggressive solvents. The resulting single-source in situ carbon-doped catalyst, α-Fe₂O₃@C (RFO-1), not only suppresses electron-hole recombination but also facilitates electron transfer during TC degradation. Remarkably, the as-synthesized α-Fe₂O₃@C (RFO-1) catalyst exhibited 96% removal of TC within 15 min in the presence of 1 mM H₂O₂, with excellent recyclability. This superior catalytic performance can be primarily attributed to its enlarged specific surface area (36.25 m²/g) and enhanced charge trapping by doped carbon, which accelerates the Fe³⁺/Fe²⁺ redox cycle and enhances reactive oxygen species (ROS) generation, thereby improving overall photo-Fenton activity. This green approach represents a promising strategy in the synthesis of transition metal oxides and can be generalized for the environmentally friendly preparation of other metal oxide photocatalysts.</div></div>","PeriodicalId":13609,"journal":{"name":"Inorganic Chemistry Communications","volume":"186 ","pages":"Article 116151"},"PeriodicalIF":5.4,"publicationDate":"2026-04-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"146035498","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":3,"RegionCategory":"化学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

The unique structure, featuring CoMn₂O₄/CoOOH composites anchored on a three-dimensional biochar network, prevents particle aggregation, maximizes active site exposure, and fosters synergistic interactions between components for accelerated electron transfer.

The intrinsic properties (i.e., crystal structure, morphology, and defect states) of the W₁₈O₄₉ were examined. While operating at RT, the W₁₈O₄₉-based gas sensor demonstrated superior behavior to acetone among eight (8) other tested gases (ethanol, methanol, m-xylene, p-xylene, o-xylene, benzene, CO, and NO₂). The sensor was exposed to a minimal concentration of 0.08 ppm acetone, resulting in a response (R_a/R_g) of 1.04. At 1.8 ppm, the response was 1.49, respectively. The repeatability measurements at 1.8 ppm revealed that the sensor could output a constant response over multiple cycles, with a standard deviation in the spread of the data of 0.1 ppm. Relative humidity (RH) measurements indicated that the sensor performed optimally in humid conditions, suggesting that humidity acted as a catalyzing agent. The sensor displayed the best responses to acetone at lower concentrations than the other gases.
