The ability to create perovskite-based heterostructures with desirable charge transfer characteristics represents an important endeavor render a set of perovskite materials and devices tunable optoelectronic properties. However, due similar material selection band alignment in type-II Z-scheme heterostructures, it remains challenging obtain favorable electron pathway for photocatalysis. Herein, we report robust tailoring effective via transformation highly efficient selective photocatalytic CO2 reduction. Specifically, CsPbBr3/TiO2 CsPbBr3/Au/TiO2 are synthesized then investigated by ultrafast spectroscopy. Moreover, taking as examples, operando experiments theoretical calculations confirm that the heterostructure could be readily transformed into through establishing low-resistance Ohmic contact, which indicates fast is crucial construction, further demonstrated CsPbBr3/Ag/TiO2 CsPbBr3/MoS2 heterostructures. In contrast pristine CsPbBr3 CsPbBr3/TiO2, exhibits 5.4- 3.0-fold enhancement consumption rate DFT situ diffuse reflectance infrared Fourier transform spectroscopy unveil superior CO selectivity attributed lower energy *CO desorption than hydrogenation *HCO. This meticulous design sheds light on modification multifunctional enlightens conscious optimization semiconductor-based catalysis applications.

Photocatalytic CO2 reduction holds great potential for alleviating global energy and environmental issues, where the electronic structure of catalytic center plays a crucial role. However, spin state, key descriptor properties, is largely overlooked. Herein, we present simple strategy to regulate states Co centers by changing their coordination environment exchanging species into stable Zn-based metal–organic framework (MOF) afford Co-OAc, Co-Br, Co-CN photoreduction. Experimental DFT calculation results suggest that distinct sites give rise different charge separation abilities barriers adsorption/activation in photocatalysis. Consequently, optimized Co-OAc with highest spin-state presents an excellent photocatalytic activity 2325.7 μmol·g–1·h–1 selectivity 99.1% CO, which are among best all reported MOF photocatalysts, absence noble metal additional photosensitizer.

Abstract The spin degree of freedom is an important and intrinsic parameter in boosting carrier dynamics surface reaction kinetics photocatalysis. Here we show that chiral structure ZnO can induce selectivity effect to promote photocatalytic performance. crystals synthesized using methionine molecules as symmetry-breaking agents hierarchical chirality. Magnetic circular dichroism spectroscopic magnetic conductive-probe atomic force microscopic measurements demonstrate acts filters induces polarization photoinduced carriers. polarized carriers not only possess the prolonged lifetime, but also increase triplet species instead singlet byproducts during reaction. Accordingly, left- right-hand exhibit 2.0- 1.9-times higher activity O 2 production 2.5- 2.0-times activities contaminant photodegradation, respectively, compared with achiral ZnO. This work provides a feasible strategy manipulate properties metal oxides for electron spin-related redox catalysis.

Abstract Engineering transition metal compounds (TMCs) catalysts with excellent adsorption-catalytic ability has been one of the most effective strategies to accelerate redox kinetics sulfur cathodes. Herein, this review focuses on engineering TMCs by cation doping/anion doping/dual doping, bimetallic/bi-anionic TMCs, and TMCs-based heterostructure composites. It is obvious that introducing cations/anions or constructing can boost capacity regulating electronic structure including energy band, d / p -band center, electron filling, valence state. Moreover, doped/dual-ionic are adjusted inducing ions different electronegativity, ion radius, resulting in redistribution, bonds reconstruction, induced vacancies due interaction changed crystal such as lattice spacing distortion. Different from aforementioned two strategies, heterostructures constructed types Fermi levels, which causes built-in electric field electrons transfer through interface, induces redistribution arranged local atoms regulate structure. Additionally, lacking studies three comprehensively for improving catalytic performance pointed out. believed guide design advanced boosting lithium batteries.
