Superhydrophilic Bimetallic Sulfide Nanosheets for Hydrogen Production Using Urea-Assisted Electrocatalytic Water Splitting

ACS Applied Nano Materials, Год журнала: 2025, Номер unknown

Опубликована: Март 26, 2025

Electrolysis of industrial and human urea-containing wastewater is beneficial to the environment, using urea oxidation reaction (UOR) instead oxygen evolution (OER) saves energy effectively improves performance electrocatalytic hydrolysis for hydrogen production. The Co9S8/Ni3S2 nanosheet structures on nickel foam (NF) are an active hydrophilic catalyst UOR (HER). This electrocatalyst needs a low overpotential 136 mV attain 10 mA·cm–2 HER, it can reach current density 100 at working potential 1.36 V vs RHE. introduction Co element regulates both morphology electronic structure. former results in Co9S8/Ni3S2/NF offering more sites with larger specific surface area morphology, while latter drives S move direction binding energy. examination cobalt sulfides as bifunctional energy-efficient electrolytic H2 production purification urea-rich harmless has significantly advanced due this work.

CoCu@NC Nanozyme with pH-Switchable and Dual Enzymatic Activity: Highly Sensitive Colorimetric Sensing of Doxorubicin and Naked-Eye Detection of H₂O₂-Induced DNA Damage

ACS Applied Bio Materials, Год журнала: 2025, Номер unknown

Опубликована: Апрель 4, 2025

The development of nanomaterials with multienzyme activity for advanced sensing and biosensing assays has attracted attention. In this study, a Cu-Co bimetallic nitrogen-doped carbon catalyst (CoCu@NC) was synthesized. prepared exhibit catalase- oxidase-like mimicking activities by adjusting the pH. catalase-like CoCu@NC investigated quenching terephthalic acid (TA) fluorescence at pH 11 in presence H2O2, while its oxidase behavior confirmed oxidation 3,3',5,5'-tetramethylbenzidine (TMB) as chromogenic substrate O2 3. Furthermore, CoCu@NC's used successfully to detect hydroquinone (HQ) concentration range 1-900 nM detection limit 0.22 anticancer drug doxorubicin (DOX) wide linear response ranging from 5 fM 200 pM an exceptionally low 1.66 reduction oxTMB TMB. DOX interacts situ single-stranded (ssDNA) double-stranded DNA (dsDNA), reducing quinone ring structure oxidizing guanine bases 8-oxoguanine. Based on phenomenon, we designed label-free colorimetric sensor measuring damage (ranging 1 μM), which operates disappearance blue solution DNA/DOX. is sensitive number ssDNA dsDNA. As (1-12) sequences increases, greater color change observed. Finally, H2O2-induced damage, no intercalation occurred between DNA-damaged sequences, observable naked eye. Therefore, visualization assay demonstrates low-cost, simple, rapid, sensitive, effective method detecting damaged DNA. Additionally, magnetic nanostructures could be easily recollected reused applying field.
