Tailoring nanoporous structures of Ge anodes for stable potassium-ion batteries

open access: yesElectrochemistry Communications, 2019
We present here for the first time the electrochemical behavior of germanium anodes in potassium-ion batteries (KIBs). Nanoporous germanium (np-Ge) samples were fabricated by the chemical-dealloying method using Al as the sacrificial metal. Galvanostatic

Carbon Capture Using Porous Silica Materials

open access: yesNanomaterials, 2023
As the primary greenhouse gas, CO2 emission has noticeably increased over the past decades resulting in global warming and climate change. Surprisingly, anthropogenic activities have increased atmospheric CO2 by 50% in less than 200 years, causing more frequent and severe rainfall, snowstorms, flash floods, droughts, heat waves, and rising sea levels ...

Formic acid oxidation over hierarchical porous carbon containing PtPd catalysts [PDF]

open access: yes, 2013
The use of high surface monolithic carbon as support for catalysts offers important advantage, such as elimination of the ohmic drop originated in the interparticle contact and improved mass transport by ad-hoc pore design.

Silicon Derived from Glass Bottles as Anode Materials for Lithium Ion Full Cell Batteries. [PDF]

open access: yes, 2017
Every year many tons of waste glass end up in landfills without proper recycling, which aggravates the burden of waste disposal in landfill. The conversion from un-recycled glass to favorable materials is of great significance for sustainable strategies.
