Perovskite materials are a research hotspot in photocatalytic applications at present, yet their performances are constrained by the weak built-in electric field, high transfer resistance of interface charges, rapid recombination of charge carriers, wide bandgap (>3.0 eV), low utilization rate for visible light, few active sites, poor adsorption capacity for reactants and slow reaction kinetics. In view of these, this study employed in-situ reduction and interface engineering strategies to reduce Bi quantum dots (Bi-QDs) onto BiOBr nanoflowers and integrate with perovskite structure Bi0.5Na0.5TiO3 for forming Z-scheme heterojunctions. The piezoelectric effect, primarily from Bi0.5Na0.5TiO3 with a minor contribution from Bi-QDs/BiOBr, effectively enhances the built-in electric field and accelerates the migration of surface charges. The Z-scheme heterojunctions could enhance the separation efficiency of photogenerated charges and accelerate the reaction kinetics. Meanwhile, the surface plasmon resonance (SPR) effect of Bi-QDs enhances visible-light absorption and works synergistically with the piezoelectric field to promote charge separation. Remarkably, it achieved efficient degradation of RhB under outdoor sunlight conditions. This design achieves the synergy of the piezoelectric effect, photocatalytic action and SPR effect, which mitigates environmental defects in conventional lead-based perovskites, enhances interfacial interactions, improves separation efficiency of photogenerated charge carrier, and significantly enhances the catalytic performance of the material.

Bismuth-based catalysts are highly active for electrochemical CO2 reduction to formate, while their uncontrolled structural reconstruction under operating conditions, especially the deep reduction of the Bi/Bi2O2CO3 heterointerface to bulk Bi0 often leads to rapid loss of formate selectivity. Here we report a ligand-engineered coordination strategy that precisely dictates the dynamic structural evolution of bismuth-based metal–organic frameworks, enabling in situ formation of stabilized Bi/Bi2O2CO3 heterointerface. By introducing an asymmetric 1H-pyrazole-4-carboxylic acid ligand, a hierarchical coordination environment is constructed, featuring coexisting Bi-O and labile Bi-N bonds. Density functional theory calculations combined with operando spectroscopic measurements reveal that the weaker Bi-N linkages selectively dissociate under cathodic polarization, initiating a controlled and stepwise transformation into crystalline Bi2O2CO3 nanosheets. This ordered reconstruction yields uniformly dispersed metallic Bi domains (<10 nm) coupled with Bi2O2CO3, forming well-defined heterointerfaces that favor formate production. The catalyst achieves a formate Faradaic efficiency of 96.3 % at −0.99 V (vs. RHE) and maintains stable performance over 8 h. This work demonstrates that the pivotal role of asymmetric coordination design in precatalysts as a means to influence reconstruction pathways at the atomic scale, providing a versatile and innovative strategy for constructing robust, selective, and dynamically adaptive electrocatalysts.

Anthraquinone (AQ) based organic conjugated polymers are promising photocatalysts for H2O2 photosynthesis from O2 and H2O, since the AQ unit with strong electron withdrawing ability can not only promote the charge separation but also act as redox active center to generate H2O2 via oxygen reduction reaction (ORR). Herein, three novel donor–acceptor type organic polymers are reported to elucidate the influence of simple donor functionalization on charge dynamics and ORR activity. Compared to biphenyl donor without functionalized group, acetylene functionalized diphenylacetylene donor and diacetylene functionalized 1,4-diphenylbutadiyne donor show reduced twisted angles between adjacent benzene rings and increased coplanarity of polymer chains, which promotes the charge transfer and separation along the polymer chains. Besides, the presence of diacetylene group in donor extends the π conjugation and broadens the light absorption range of DPB-AQ. Benefiting from the donor–acceptor structure, broad absorption range of visible light, upgraded charge transfer and separation ability, DPB-AQ exhibits a higher photocatalytic H2O2 yield of 7.8 mmol h−1 g−1 than BPH-AQ (1.0 mmol h−1 g−1) and DPA-AQ (3.8 mmol h−1 g−1) in pure water without additives. This work highlights the critical role of simple donor functionalization in polymers for H2O2 photosynthesis from H2O and O2.

A family of new ligands (L1–L8) and non-pincer-type PN-Mn(I) complex Mn1 containing the imidazoline motif have been successfully employed for the transfer hydrogenation of N-unprotected indoles with H3NBH3 (AB) as the hydrogen source, giving high efficiencies (TON up to 7200) and good compatibility with functional groups, which surpasses the activity of most effective noble metal catalysts for this reaction. The reaction kinetics investigations, control experiments, and DFT computations highlighted that the central amido/amino-based bifunctional activation step employed a concerted N–H and B-H activation reaction pathway, and the hydride/proton-transfer process is the rate-determining step. More importantly, a proposed catalytic cycle involves an outer-sphere pathway for the reduction of the isomerized CN bond rather than the CC bond in the indole. Furthermore, this catalytic protocol provides a convenient and efficient method for the synthesis of a wide variety of indolines (26 examples) and saturated N-heterocycles such as tetrahydroberberine (2 examples).

Crystalline palladium phosphide nanoparticles supported on silica (Pd3P/SiO2, 5 wt% Pd) are explored as catalysts for the alkoxycarbonylation of lignin-derived aromatic synthons, using model aryl halides as representative substrates. The detailed characterization by PXRD, HAADF-STEM, HRTEM, EDX, ICP-AES, XPS, CO-DRIFTS, and CO chemisorption confirmed the formation of the Pd3P phase with uniform nanoparticle size distribution. The catalytic performance was evaluated in a three-phase reaction system comprising a CO gas atmosphere, a liquid phase containing the solvent and substrate and a solid catalyst. The incorporation of phosphorus into the palladium lattice resulted in a more than two-fold enhancement in catalytic activity compared to conventional Pd-based heterogeneous catalysts. The Pd3P/SiO2 catalyst also outperformed several reported heterogeneous and commonly used homogeneous catalysts. This enhanced reactivity is attributed to the electronic and geometric effects introduced by phosphorus, which generate highly active, spatially-isolated Pd sites. These findings demonstrate the potential of Pd–P phase engineering for the design of the next-generation of carbonylation catalysts.
