In₂O₃ Nanoparticle/Bi₄O₅Br₂ Nanosheet S-Scheme Heterojunctions with Interfacial Oxygen Vacancies for Photocatalytic Degradation of Tetracycline

ACS Applied Nano Materials, Journal Year: 2023, Volume and Issue: 6(13), P. 11877 - 11887

Published: June 29, 2023

The development of highly efficient photocatalysts for antibiotics contamination in water remains a severe challenge. In this study, In2O3 nanoparticle/Bi4O5Br2 nanosheet S-scheme heterojunction with interface oxygen vacancies (OVs) was constructed by hydrothermal-calcination approach and simple chemical precipitation process. Under simulated sunlight, composite showed enhanced degradation efficiency tetracycline hydrochloride (TCH) 92.4%, which much higher than those pure Bi4O5Br2 (50.2%) (28.6%). excellent removal mainly attributed to the synergistic effect heterojunctions OVs accelerating complexation unwanted electrons (e–) holes (h+), thus retaining e– strong oxidizing ability h+ reducing participate reaction. addition, abundant nanoparticles/Bi4O5Br2 nanosheets could enhance adsorption O2 promote generation superoxide radicals (·O2–). toxicity products catalyst evaluated E. coli growth inhibition experiments. Based on TCH intermediates detected HPLC-MS, three possible pathways were proposed. This study shows that construction interfacial defects is an effective strategy preparation photocatalysts.

Multistep Quenching of a Rust-Derived Catalyst for Enhanced Volatile Organic Compound Catalytic Oxidation

ACS Catalysis, Journal Year: 2024, Volume and Issue: 14(9), P. 7201 - 7212

Published: April 24, 2024

The advancement of cost-effective Pt catalysts for volatile organic compound (VOC) combustion holds significant importance. Enhancing the adsorption and activation O2 VOCs on is vital VOC oxidation reaction. In this study, we utilized a two-step quenching method to alter iron rust, resulting in deposition species Sn-doped Fe2O3 sample (Ptq/Snq:Fe2O3). Experiments theoretical calculations revealed that both process Sn dopants would induce generation oxygen vacancies, improving mobility Ptq/Snq:Fe2O3. Also, doping enhance interaction between support modulate Pt's electronic structure, promoting toluene desorption product CO. Thus, developed Ptq/Snq:Fe2O3 exhibited boosted toluene/acetone activity, achieving 90% mineralization rate at 215 °C acetone 228 °C, respectively. situ diffuse reflectance infrared Fourier transform spectroscopy showcased vacancy with modulated structure synergistically heightened acetone/toluene, accelerated ring breakage toluene, brought about thorough This research could offer potential avenue fine-tuning active sites crucial catalytic processes.

Highly Self-Healing Co³⁺/Ni³⁺ Dual-Active Species for the Electrocatalytic Oxidation of 5-Hydroxymethylfurfural

Inorganic Chemistry, Journal Year: 2024, Volume and Issue: 63(35), P. 16541 - 16553

Published: Aug. 21, 2024

Electrocatalytic conversion of 5-hydroxymethylfurfural (HMF) to 2,5-furandicarboxylic acid (FDCA) is significant for the sustainable production value-added chemicals. Active sites catalysts could enhance activity and selectivity HMF oxidation reaction (HMFOR), but self-healing ability active has been commonly ignored. In this work, Co(OH)2/Ni-MOF was successfully fabricated efficient FDCA under mild conditions. Electrochemical cyclic stability experiments demonstrated high properties dual (Co3+/Ni3+). So, retention rate yield can still reach 98.5%, even after 90 days. HMFOR further coupled with 4-nitrophenol hydrogenation, which promotes Faradaic efficiency about 100%. Therefore, study explores species provides new insights designing catalysts.
