Interfacial electron redistribution in a TiO2/Mn3O4 hollow heterostructure for selective photocatalytic CO2-to-CO conversion.
Selective photocatalytic CO2-to-CO conversion remains challenging because of rapid charge recombination and insufficient CO2 activation. Herein, a TiO2/Mn3O4 hollow heterostructure was constructed through a SiO2 hard-template strategy combined with in situ growth. The hollow hemispherical architecture provides an open...
