Mesoporous silica nanoparticles (MSNs) were synthesized hydrothermally and modified with Co2+ and Zn2+. The as-prepared samples were denoted as MSN, Co-MSN(X), and Zn-MSN(X), where X is the Si/M molar ratio. In addition, co-modified MSN samples with both cations were also prepared and denoted as Co-Zn(Y)-MSN(X), where Y indicates the Zn2+ content in the range of […]
