Direct conversion of CO and H_(2)O to hydrocarbons at atmospheric pressure using a TiO_(2-x)/Ni photothermal catalyst

引用

Science China Materials 2024年第3期67卷 1009-1010页

作者： yan zhu School of Chemistry and Chemical Engineering Nanjing UniversityNanjing 210093China

Generating high-value chemical compounds by catalytically converting carbon resources—typically derived from coal and biomass, etc.—is crucial. It is more meaningful to achieve“carbon neutrality” and lower production costs by utilizing industrial waste carbon sources, such as steel mill waste gases,which are typically intended for direct emission or burning into CO_(2).
