Graphical Abstract

Banish the villains to their own realm: Biomass has gained widespread attention as a renewable energy source. However, commercial catalysts used in power plants (co-)fuelled by biomass are deactivated by the alkali-rich flue gas (see graph, black line). In contrast, one of two types of active sites in a promising alkali-resistant hollandite catalyst traps alkali-metal ions to free up the catalytically active sites for the reduction of NO by NH3.
