Impact of carbon on the surface and activity of silica-carbon supported copper catalysts for reduction of nitrogen oxides

- C predetermines the composite's texture, micro- and mesopores, pore volume.
- IEPs of C and SiO2 determine their different distribution on the surface.
- Cu on different silica-carbon composites is in different oxidation states.
- NO with CO proceeds by different paths due to the textural and surface differences.
