Abstract: In this study, we successfully synthesized amine-functionalized SBA-15 mesoporous silicasupported
Nickel nanoparticles (Ni NPs) and investigated their potential for CO2 transition to formic
acid via high-pressure hydrogenation reaction. The metal-support interface between the Ni NPs and
the amine-functionalized SBA-15 mesoporous silica was examined using various techniques, including
BET, TEM, and XPS analyses. Our findings reveal a robust metal-support interaction between the
NiNPs and the mesoporous silica substrate, highlighting the suitability of the catalyst for the CO2
conversion reaction. Additionally, the catalyst CAT$Ni-1 exhibited good catalytic activity over
CAT$Ni-2 and CAT$Ni-3, and we were able to recycle them up to five runs with no significant reduction
in catalytic activity. These results suggest that the synthesized Ni NP catalysts have the potential
for large-scale CO2 conversion, contributing to the development of sustainable technologies for
reducing greenhouse gas emissions.
