The release of microplastics (MPs) into the environment has engendered considerable ecosystem and human health concerns. Herein, we propose light-driven photocatalytic upcycling MPs using heterojunction photocatalysts. A novel synthesis method was developed through in-situ conversion unstable metal sites on bimetallic metal-organic frameworks (MOF), resulting in nanometer-sized particles with s...
We report progress towards understanding how phonon anharmonicity contributes to negative thermal expansion (NTE). Some contribution to the NTE is from "quasiharmonic" behavior, where phonon frequencies decrease as a crystal expands. A second "anharmonic" effect from phonon-phonon interactions is sometimes calculated by perturbation theory, but sometimes the anharmonic effects are too large to ...
A Pt-Ag/graphene composite (Pt-Ag/GNs) was synthesized by the facile aqueous solution method, in which Ag+ was first transformed into Ag2O under UV light irradiation, and then Ag2O, Pt2+, and graphene oxide (GO) were simultaneously reduced by formic acid. It was found that Pt-Ag bimetallic nanoparticles were highly dispersed on the surface of graphene, and their size distribution was narrow wit...
Facile tuning of plasmon bands in hollow silver nanoshells using mild reductant and mild stabilizer.
Hollow silver nanoshells with tunable plasmon bands have been synthesized using Ag2O nanoparticles at an optimized temperature of 20 °C. The plasmon peak has been tuned in a wide range from 460 nm to 605 nm employing a combination of mild reductant and a mild stabilizer, hydrazine hydrate and sodium citrate, respectively. In contrast, the combination of strong reductant and strong stabilizer, N...
در این پروژه حذف فوتوکاتالیتیکی رودامینb توسط سیستم uv/bi2o3 مطالعه گردید و متیل اورانژ توسط سیستم vis light/ag2o-bi2o3 مورد بررسی قرار گرفت. نانو بیسموت اکسید با استفاده از روش رسوبی و نانو کامپوزیت ag2o-bi2o3 به روش هم رسوبی تهیه گردید . نمونه های سنتز شده توسط الگوی پراش پرتو ایکس، میکروسکوپ الکترونی روبشی و اسپکتروسکوپی تبدیل فوریه ir شناسایی شدند. بررسی ساختاری نشان داد بیسموت اکسید سنتزی ...
Ag2O thin films have been applied in various devices, such as photodetectors, photocatalysts, and gas sensors, because of their excellent thermal stability, strong electrical properties, stable structures. However, phases silver oxide exist, the fabrication single-phase using a general deposition system is difficult. In this study, were deposited on glass substrates at different working pressur...
