WebJan 12, 2024 · In this work, we have successfully constructed carbon nanotube (CNT)-a-CoSx amorphous heterostructured catalysts using a two-step method. The abundant active sites, superior electron transport properties, and large electrochemically active specific surface area enable amorphous CNT-a-CoSx to exhibit higher hydrogen evolution … WebIf you compare an amorphous phase with crystalline phase of a same drug, the amorphous phase always show higher free energy, enthalpy, and entropy than the crystalline one. To be simple and...
