Removal of phorate and terbufos by Fenton coagulation
, 2010 碩士本研究以有機磷農藥之福瑞松 (Phorate)及托福松(Terbufos)為目標物，研究目的為（1）探討Fenton混凝去除福瑞松與托福松、及（2）比較鐵鹽混凝、Fenton及Fenton-like混凝去除福瑞松與托福松。所有實驗採瓶杯試驗，人工原水含有機磷農藥濃度為100 μg/L，操作參數為pH、鐵鹽種類、過氧化氫(H2O2)加藥量及腐植酸有機物共存，鐵鹽加藥量以Fe2+或Fe3+計之。 研究結果顯示鐵鹽(Fe2+/Fe3+)混凝去除福瑞松及托福松之最適pH為 4.0 ...

Advanced Science, EarlyView.A recycling approach of spent lithium‐ion batteries is developed using brewing wastewater as the leaching agent and an engineering microbial consortium as the biocatalyst. Shewanella oneidensis reduces spent LiNixCoyMn1‐x‐yO2 cathodes via extracellular electron transfer, while Bacillus subtilis removes residual ethanol to eliminate inhibition.

Angewandte Chemie, EarlyView.Two isostructural conjugated‐MOFs (Fe‐Tp and Mn‐Tp) photocatalysts were engineered with nonequivalent microenvironmental redox tuning for hydrogen peroxide production. The manganese analog engages both the oxygen reduction reaction and the water oxidation reaction while suppressing decomposition, delivering 10 487 µmol g−1 h−1 with an apparent quantum ...

Advanced Science, EarlyView.Nebulized BN@NF nanozymes integrate boron nanosheets with Nd‐doped iron phosphide to form a sono‐magneto‐responsive Z‐scheme heterostructure. Under ultrasound and magnetic activation, BN@NF amplifies ROS generation, eradicates bacteria, disrupts biofilms, and reshapes pulmonary inflammation through NF‐κB suppression, mitophagy promotion, and M1‐to‐M2 ...

Angewandte Chemie, EarlyView.Using defect‐rich Co‐N2O2 single‐atom catalysts as a model system, this work reveals that atomic site density governs the competition between H2O2 electrosynthesis and microenvironmental decomposition during 2e−‐ORR. Optimised site isolation suppresses HPRR and HDR, thereby establishing a site‐density principle to balance H2O2 formation and ...

Advanced Energy Materials, EarlyView.This work introduces a CeHP‐enabled multifunctional matrix‐activated electrode (MME) for high‐temperature PEM fuel cells, forming an electrochemically and mechanically functional matrix within the catalyst layer. The design increases peak power density by 38% and reduces voltage decay by 62% at 240 °C, while using only 40% of the Pt loading of a ...

Angewandte Chemie, EarlyView.Dehydroamino acids (DHAA) are atypical electrophilic sites that lead to crosslinked proteins in Alzheimer's disease (AD) brains. No catalyst for their formation has been known in humans. We report that metal oxides catalyze β‐elimination of phosphoserine and phosphothreonine in model peptides at pH 7.5°C and 37°C, yielding DHAAs.
