Abstract Selective photoreduction of carbon dioxide (CO 2 ) into high‐value C products remains a formidable challenge due to the elusive C−C coupling step. Herein, novel concept is first introduced that an amorphous‐crystalline hybrid structure can galvanize previously inert metal atoms, thereby establishing highly active dual sites. This ingenious configuration promotes coupling, paving way for CO products. Taking Bi MoO 6 nanosheets anchored by amorphous FeOOH species as example, X‐ray photoelectron spectroscopy (XPS) spectra and absorption near edge density functional theoretical (DFT) calculations confirm electron transfer from nanosheets. Thus, introduction activates nonoperative sites construction Bi−Mo sites, verified in situ XPS DFT calculations. Gibbs free energy revealed formation barrier hugely lowed 3.41 0.45 eV thanks presence species. Therefore, FeOOHBi are game changer, delivering sole liquid product, acetic acid, with impressive selectivity ≈86.9%. In contrast, lag behind, only capable producing monoxide photoreduction.

Abstract Photocatalytic CO 2 reduction into high‐value C 2+ products such as H 6 is of great importance but challenging due to their multi‐electron steps and high energy barrier C─C coupling. Moreover, improving its solar‐to‐chemical (STC) conversion efficiency in pure water beyond the current 1% empirical value also a significant challenge. Herein, graphite carbon nitride (g‐C 3 N 4 ) nanosheets with controllable (C) doping nitrogen (N) vacancies (PCCN‐x) are designed through biochar‐tailored protocol for efficiently selectively photo‐converting . The optimal PCCN‐10 photocatalyst enables achievement an exceptional activity 99.14 µmol g −1 h selectivity 80.33% over 20 water. A record STC ≈1.13% solar fuel production from O vapor achieved without any other inputs. Outdoor tests demonstrated impressive ‐to‐C photo‐conversion rate 43.17 water, stable 50 period. Critically, experimental theoretical calculations further confirm pivotal role bridged sites activating molecules promoting formation coupling intermediate ( * OCCO), which very beneficial performance this work photocatalytic fuels paves way large‐scale broader sustainable applications.

Abstract Photocatalytic CO 2 reduction to high‐value‐added C 2+ products presents significant challenges, which is attributed the slow kinetics of multi‐e − photoreduction and high thermodynamic barrier for C–C coupling. Incorporating redox‐active Co /Ni cations into lead halide photocatalysts has potentials improve carrier transport introduce charge polarized bimetallic sites, addressing kinetic issues, respectively. In this study, a coordination‐driven synthetic strategy developed 3d transition metals interlamellar region layered organolead iodides with atomic precision. The resultant hybrids exhibit selective H 5 OH using O vapor at evolution rates 24.9–31.4 µmol g −1 h selectivity 89.5–93.6%, while pristine iodide yields only 1 products. Band structure calculations photoluminescence studies indicate that interlayer species greatly contribute frontier orbitals enhance exciton dissociation free carriers, facilitating between adjacent layers. addition, Bader distribution in situ experimental spectroscopic reveal asymmetric Ni–O–Pb catalytic sites intrinsic polarization, promoting coupling leading formation key *OC–CHO intermediate.

Abstract Halide perovskites have garnered significant attention for their unique optoelectronic properties in solar‐to‐fuel conversions. However, the efficiency of halide field photocatalytic CO 2 reduction is largely limited by serious charge recombination and a lack efficient active sites. In this work, rubidium (Rb) doped Cs AgBiBr 6 (Rb:CABB) hierarchical microsphere developed reduction. Experimental theoretical analysis discloses that partially substituting Rb + Ag can effectively modulate electronic structure CABB, favoring separation making adjacent Bi atoms an electron‐rich site. Further investigations indicated doping also reduces energy barriers rate‐determining step As result, Rb:CABB demonstrated enhanced yield compared to its undoped counterpart. This work presents promising approach optimizing structures photocatalysts paving new way exploring
