Abstract null null Pyrolyze metal-organic frameworks (MOFs) is a promising method to prepare metal oxides with large specific surface and multiple active sites. The obtained metal oxides can be utilized as gas sensors. Noble metal doping is an effective way to improve the gas sensitivity of materials. In this work, SnO2 are prepared by pyrolyzation of metal organic frameworks and Ag-doped SnO2 composites are fabricated by AgNO3 reduction in a water bath at 4 °C. The gas-sensing experiment reveal...

Porous structures and heterogeneous compositions are highly desirable to achieve improved sensing performance. Herein, a SnO2/Co3O4 composite with catalytic sites and abundant oxygen vacancies has been successfully synthesized by pyrolyzation of Sn- and Co-based bimetallic organic frameworks (bMOFs). The composites demonstrate desirable p–n heterojunctions, which was confirmed by diffuse reflection ultraviolet–visible spectroscopy (DRS) and Mott–Schottky (M–S) plots. Gas-sensing experiments reve...

Potassium ion batteries (PIBs) have drawn considerable interest because of the resource-abundance and tempting electrochemical potential of potassium. However, developing high-performance anodes for PIBs with superior reversible capacity and ultralong stability is still a huge challenge to meet the requirements of sustainable and cost-effective large area energy storage systems. To address the above-mentioned issues, we report for the first time a simple in situ growth strategy to synthesize pil...

Abstract The rGO-NiO/ZnO composites were successfully synthesized by hydrothermal and hydrazine hydrate reduction methods and were used to detect NO2. The structure and morphology of the composites were characterized using spectrum techniques. The sensing tests showed that the triadic composite of rGO (0.5 wt%)-NiO/32ZnO exhibits a liner response toward NO2 in the concentration range of 0.5 – 3 ppm and the highest response reaches 75.3 to 2 ppm NO2 at 140 °C, which is 4.55 times and 1.38 times h...

Abstract The volatile gas of Triethylamine (TEA) can cause environment pollution and lead to the serious hurt of the human respiratory system. Therefore, it is necessary to detect low concentrations of TEA in our daily lives rapidly. The hybrid of pine dendritic BiVO4/reduced graphene oxide (rGO) has been synthesized firstly by one step hydrothermal process. The gas sensing tests show that the 13.0 wt% rGO hybrid not only exhibits high response of 5.9 and rapid response of 11.4 s, but also exclu...

Abstract Photoelectrochemical (PEC) water splitting technology offers a sound strategy for the production of chemical energy using abundant solar energy. Herein, a ternary photoanode of SnO2/BiVO4/rGO was fabricated by plain chemical vapor deposition (CVD) and metal-organic decomposition followed by spin-coated rGO on the SnO2/BiVO4 junction. The ternary photoanode yields the highest photocurrent density of 2.05 mA cm−2 at 1.23 V vs. RHE, which is 3.73 times of the BiVO4 photoanode (0.55 mA cm−2...

Abstract A series of Eu3+ doped Y2O3 nanophosphors have been synthesized via an ultra-fast ultrasonic-microwave method followed by thermal annealing. The emission of Y2O3:Eu3+ nanophosphors depends tremendously on the concentration of Eu3+ ions and maximum emission intensity is achieved at 612 nm (red luminescence) with a doping concentration of 3 mol%. Moreover, the Y2O3:Eu3+ nanophosphors in this work have much higher photoluminescence lifetime (1.570 ms) and quantum efficiency (80.88%) than t...

Abstract Purification of small bioactive peptides from complex biological samples is a difficult task due to the interference of concentrated large biomolecules. In this study, a magnetic immobilized metal affinity chromatography matrix modified by poly (ethylene glycol) methyl ether (IMACM@mPEG) was prepared and applied for the rapid purification of angiotensin I-converting enzyme (ACE) inhibitory peptides from casein hydrolysate. The proposed IMACM@mPEG considerably reduced the non-specific ad...
