Article Abstract
Selective CO photoreduction to C hydrocarbons is significant but limited by the inadequate adsorption strength of the reaction intermediates and low efficiency of proton transfer. Herein, an ameliorative *CO adsorption and HO activation strategy is realized via decorating bismuth oxychloride (BiOCl) nanostructures with different metal (Pt, Pd, and Au) species. Experimental and theoretical calculation results reveal that distinct *CO binding energies and *H acquisition abilities of the metal cocatalysts mediate the CO reduction activity and hydrocarbon selectivity. The relatively moderate *CO adsorption and *H supply over Pd/BiOCl endows it with the lowest free energy to generate *CHO, leading to its highest activity of hydrocarbon production. Specifically, the Pt cocatalyst can efficiently participate in HO dissociation to deliver more *H for facilitating the protonation of the *CHO and *CHOH, thereby favoring CH production with 76.51% selectivity. A lower *H supply over Pd/BiOCl and Au/BiOCl results in a large energy barrier for *CHO or *CHOH protonation and thus a more thermodynamically favored OC─CHO coupling pathway, which endows them with vastly increased C hydrocarbon selectivity of 81.21% and 92.81%, respectively. The understanding of efficient C hydrocarbon production in this study sheds light on how materials can be engineered for photocatalytic CO reduction.

Effective removal of ethylene (CH) during fruit and vegetables storage and transport remains a critical challenge for post-harvest preservation. Although S-scheme heterojunctions can improve charge separation and redox capacity for ethylene degradation, their efficiency is still restricted by limited carrier transfer and sluggish oxygen activation. Here, we rationally designed a novel 2D/2D SnNbO/BiMoO monolayer S-scheme heterojunction integrated with Pt co-catalyst to address these limitations.

Solar-driven photocatalytic oxygen reduction reaction using covalent organic frameworks (COFs) offers a promising approach for sustainable hydrogen peroxide (HO) production. Despite their advantages, the reported COFs-based photocatalysts suffer insufficient photocatalytic HO efficiency due to the mismatched electron-proton dynamics. Herein, we report three one-dimensional (1D) COF photocatalysts for efficient HO production via the hydrogen radical (H•) mediated concerted electron-proton transfer (CEPT) process.

Confronting the dual challenges of carbon neutrality and sustainable energy, photocatalytic CO reduction requires precise control over product selectivity. This study demonstrates that surface hydroxyl (-OH) density serves as a molecular switch for reaction pathways in graphene oxide/cobalt tetraphenylporphyrin (GO/CoTPP) hybrids. By tuning the reduction degree of GO supports via gradient hydrazine hydrate treatment (0-85%), we constructed catalysts with controlled -OH concentrations.

Metal-organic frameworks (MOFs) are distinguished by their structural diversity, tunable electronic properties, and exceptional performance in various applications. Notably, the electron-donating ability of ligands significantly enhances the ligand-to-metal charge transfer (LMCT) processes within these frameworks, thereby promoting efficient charge migration. Herein, we developed two electron-rich macrocyclic ligands derived from phenothiazine- and phenoxazine-functionalized calix[3]arenes, alongside their corresponding cobalt-coordinated MOFs.
