Microwave-assisted hydrothermal synthesis of carbon monolith via a soft-template method using resorcinol and formaldehyde as carbon precursor and pluronic F127 as template

chemical recycling of polycarbonate waste using conventional heating and microwave assisted method

پلی کربنات یکی از پلاستیکهای مهمی است که به صورت گسترده در تولید لوحهای فشرده، قطعات رایانه، مواد ساختمانی و غیره مورد استفاده قرار می گیرد. این پلیمر بصورت عمده از تراکم مونومر بیس فنولa (bpa) و کربنیل کلرید یا دی متیل کربنات ها بدست می آید. در سالهای اخیر بازیافت شیمیایی پلی کربنات بیشتر مورد توجه بوده است. بازیافت شیمیایی پلی کربنات برای بدست آوردن مواد اولیه آن با روشهای متفاوتی مانند تجزی...

Template method synthesis of mesoporous carbon spheres and its applications as supercapacitors

Mesoporous carbon spheres (MCS) have been fabricated from structured mesoporous silica sphere using chemical vapor deposition (CVD) with ethylene as a carbon feedstock. The mesoporous carbon spheres have a high specific surface area of 666.8 m2/g and good electrochemical properties. The mechanism of formation mesoporous carbon spheres (carbon spheres) is investigated. The important thing is a s...

Controlled synthesis of core/shell magnetic iron oxide/carbon systems via a self-template method

Microwave–Assisted Hydrothermal Synthesis and Optical Characterization of SnO2 Nanoparticles

Semiconductor nanoparticles exhibit size dependent properties due to quantum confinement effect that are not present in their bulk counterparts. In this work, extremely fine and pure SnO2 nanoparticles of ~1.1 nm size were synthesized by a solution process, in which amorphous precipitate of SnO2 was crystallized by microwave heating. The particles sizes varied from ~1.1 to ~2.7 nm. By XRD analy...

Control over Porosity using Isoreticular Zeolitic Imidazolate Frameworks (IRZIFs) as Template for Porous Carbon Synthesis

Herein, using Isoreticular Zeolitic Imidazolate Frameworks (IRZIFs) as template, we report the synthesis, morphology and gas adsorption properties of porous carbon synthesized by nanocasting method at 1000 C, where furfuryl alcohol (FA) has been used as a carbon source. Using IRZIFs with variable porosity as templates, we could achieve the control over carbon porosity, H2 and CO2 uptake. The r...
