Three-layered nanoplates and amorphous/crystalline interface synergism boost CO photoreduction on bismuth oxychloride nanospheres.

Structural features like 3D nano-size, ultrathin thickness and amorphous/crystalline interfaces play crucial roles in regulating charge separation and active sites of photocatalysts. However, their co-occurrence in a single catalyst and exploitation in photocatalytic CO reduction (PCR) remains challenging. Herein, nano-sized bismuth oxychloride spheres (BiOCl-NS) confining three-layered nanoplates (∼2.

Rubidium Doped CsAgBiBr Hierarchical Microsphere for Enhanced Photocatalytic CO Reduction.

Halide perovskites have garnered significant attention for their unique optoelectronic properties in solar-to-fuel conversions. However, the efficiency of halide perovskites in the field of photocatalytic CO reduction is largely limited by serious charge recombination and a lack of efficient active sites. In this work, a rubidium (Rb) doped CsAgBiBr (Rb:CABB) hierarchical microsphere is developed for photocatalytic CO reduction.

Regulating the Active Sites of Cs AgBiCl by Doping for Efficient Coupling of Photocatalytic CO Reduction and Benzyl Alcohol Oxidation.

Halide perovskites exhibit outstanding optoelectronic properties, which make them an ideal choice for photocatalytic CO reduction and benzyl alcohol (BA) oxidation. Nevertheless, the simultaneous realization of the above redox coupling reactions on halide perovskites remains a great challenge, as it requires distinct catalytic sites for different target reactions. Herein, the catalytic sites of Cs AgBiCl (CABC) are regulated by doping Fe for efficient coupling of photocatalytic CO reduction and BA oxidation.

In-situ producing CsPbBr nanocrystals on (001)-faceted TiO nanosheets as S‑scheme heterostructure for bifunctional photocatalysis.

Fabricating a cost-effective yet highly active photocatalyst to reduce CO to CO and oxidize benzyl alcohol to benzaldehyde simultaneously, is challenging. Herein, we construct an S-scheme 0D/2D CsPbBr/TiO heterostructure for bifunctional photocatalysis. An in-situ synthetic route is used, which enables the precise integration between CsPbBr nanocrystals and ultrathin TiO nanosheets exposed with (001) facets (termed as TiO-001), resulting in a tightly coupled heterointerface and desirable band offsets.
