Formation of carbonate minerals by CO2 sequestration is a potential means to reduce atmospheric CO2 emissions. Vast amount of alkaline and alkali earth metals exist in silicate minerals that may be carbonated. Laboratory experiments carried out to study the dissolution rate in Pahang Sandstone, Malaysia, by CO2 injection at different flow rate in surficial condition. X-ray Powder Diffraction (X...

The kinetics of the hydrogen evolution reaction (HER) at gold electrodes is affected by concentration alkali metal cations and electrolyte pH. At moderately alkaline pH, increasing cation greatly enhances HER activity. Cations are proposed to help stabilize transition state rate-determining Volmer step a favorable interaction with dissociating water molecule (*H–OHδ−–cat+).
