Calcination of Strontium Carbonate in Rotary Kiln Furnace

, 2019
The calcination of the strontium carbonate in the rotary kiln is usually carried out at temperatures as high as 1300 °C in practical applications. During the calcination process, partial melting of powders occurs at about 1150 °C, due to the partial pressure of CO2.

Photoreduction of carbon dioxide using strontium zirconate nanoparticles [PDF]

Science China Materials, 2015
The utilization of CO2 and solar energy have drawn much attention due to global warming and fuel crisis. Of particular interest in our research, we prepared strontium zirconate (SrZrO3) nanoparticles as the photocatalyst to convert CO2 into value-added products. SrZrO3 nanoparticles were successfully synthesized via a sonochemical method and applied to

Photocatalytic Versus Stoichiometric Hydrogen Generation Using Mesoporous Silicon Catalysts: The Complex Role of Sacrificial Reagents

Advanced Functional Materials, EarlyView.
This study highlights the importance of accounting for stoichiometric hydrogen produced when utilizing Si photocatalysts. The stoichiometric contribution is sacrificial reagent dependent and decreases with increasing sterics around the catalyst surface.

Composites of Shellac and Silver Nanowires as Flexible, Biobased, and Corrosion‐Resistant Transparent Conductive Electrodes

Advanced Functional Materials, EarlyView.
Shellac, a centuries‐old natural resin, is reimagined as a green material for flexible electronics. When combined with silver nanowires, shellac films deliver transparency, conductivity, and stability against humidity. These results position shellac as a sustainable alternative to synthetic polymers for transparent conductors in next‐generation ...

Decoupling Size and Electronic Effects in Doped SrTiO3 Photocatalysts Through Surface Area–Normalized CO2 Hydrogenation Rates

Advanced Functional Materials, EarlyView.
Exploring the photocatalytic reverse water–gas shift (RWGS) reaction on doped SrTiO3 nanoparticle films, reveals that normalizing catalytic rates by the catalyst's specific surface area (SSA) disentangled surface area effects from the catalyst's intrinsic material properties.
