Preparation and characterization of CaO-Al2O3-SiO2 glass-ceramic microspheres from coal-based solid waste 

Silicon
Abstract To alleviate the environmental pollution caused by the stockpile of coal-based solid waste, glass-ceramic microspheres prepared by a simple and low-cost wet process with coal-based solid waste, and the effect of different solid waste content on the network structure and properties were investigated by X-ray diffraction(XRD), Fourier ...

State‐of‐the‐Art and Synthetic Challenges for Hydrosilane Production

Chemistry – A European Journal, EarlyView.
The synthesis of hydrosilanes is currently energy intensive and their recycling is not considered. However, these compounds are important in many industrial fields but also for the valorization of oxygenated waste, towards a circular economy. This review compares the available synthetic routes and highlights the remaining challenges for the production ...

In situ Generation of Fluoride Catalysts for CO2‐to‐Formic Acid Conversion With Silicon Reducing Agent

Chemistry – A European Journal, EarlyView.
Reductive conversion of CO2 to formic acid with waste silicon reducing agent catalyzed by in situ generation of active fluoride species from a tertiary amine, protonic acid, and simple inorganic fluoride salt, such as KF and NaF. ABSTRACT The activation and catalytic reduction of carbon dioxide (CO2) using silicon‐based reducing agents is an important ...

Sustainable Germanium Recovery From Germanium Dioxide via Halogen‐Free Chemical Vapor Transport

Chemistry – A European Journal, EarlyView.
Recovery of the critical element Ge from GeO2 and SiO2/GeO2 mixtures was investigated based on an endothermic chemical vapor transport via GeO, formed with natural gas or a hydrogen(10%)‑argon(90%) mixture and water vapor. (This picture was partly created with AI, engine: Adobe Firefly).
