While metal phthalocyanines (MPc) exhibit excellent CO₂ reduction capabilities, their practical application in dispersed photocatalytic systems faces limitations of the stacking of MPc molecules that reduces active site accessibility, and inefficient electron transfer limited by diffusive mass transport. To address these challenges, we developed a bioinspired dye-sensitized RuP-TiO₂-FePc nanosheets (NSs) hybrid system, where ultrathin FePc NSs obtained by liquid-phase ultrasonic exfoliation enhance active site exposure and mass transfer, while TiO₂ serves as a mediator to facilitate electron transfer between the photosensitizer and FePc NSs. Time-resolved spectroscopic studies demonstrate that TiO₂ plays a dual role: it spatially organizes functional components to enable surface electron transfer by shortening intermolecular distances, while also functioning as a semiconductor bridge to facilitate charge transport. This synergistic design achieves a remarkable CO production rate of 27.3 mmol g^–1 h^–1 (&gt; 98% selectivity) and exceptional stability (TON_CO = 1363 over 100 h), outperforming many noble-metal-based systems.

This study employs density functional theory calculations to systematically investigate the effects of transition metal (TM = Cr, Mn, Fe, Co, and Ni) doping at distinct sites of a CdS/ZnO S-scheme heterojunction: the surface (TM_s), the interface (TM_i), and co-doping at both sites (TM_s+i). The results demonstrate that all doping configurations concurrently enhance both interfacial electron transfer and the hydrogen evolution reaction dynamics. The augmentation of electron transfer across the interface is primarily driven by TM doping at the interface, which reduces the work function of CdS and enlarges the Fermi level discrepancy with ZnO, leading to an enhancement trend of TM_s+i &gt; TM_i &gt; TM_s. Conversely, the optimization of hydrogen adsorption free energy (Δ<em>G</em>_H*) is chiefly governed by surface TM doping, which downshifts the <em>p</em>-band center of S atoms and weakens the S–H bond, resulting in an improvement trend of TM_s+i &gt; TM_s &gt; TM_i. Remarkably, the co-doping configuration exhibits a pronounced synergistic effect, outperforming any single-site doping in optimizing both properties. Furthermore, a clear periodic trend is identified: the promotional effect of TM doping, from Cr to Ni, progressively diminishes for both charge separation and surface reaction, which is linked to the increasing work function and S <em>p</em>-band center.

Herein, we first report the morphology-controlled synthesis of CaCO₃ with distinct crystalline phases (<em>e.g.</em>, rhombohedral calcite, spherical vaterite, and rod-shaped aragonite). This engineered morphology significantly enhances co-thermal coupled in-situ reduction, simultaneously lowering the decarboxylation temperature and promoting syngas formation. Compared with rhombohedral calcite, spherical vaterite exhibits superior CO selectivity and formation rate during reduction processes across various temperatures, reaching 96% and 0.80 mmol min^–1 at 700 °C, respectively. Notably, rod-shaped aragonite achieves an exceptional CO selectivity of 86%, surpassing both rhombohedral calcite and spherical vaterite, and the CO formation rate (0.46 mmol min^–1) is more than 2.3 times that of spherical vaterite at 550 °C. Moreover, combination of temperature programmed reduction-mass spectrometry and <em>in-situ</em> diffuse reflectance infrared Fourier transformed experiments reveals temperature-dependent hydrogenation mechanisms for different morphologies of CaCO₃: direct hydrogenation dominates at relatively low temperatures, while at elevated temperatures, the dual mechanism combining direct hydrogenation and reverse water-gas shift reaction (HCOO* as the key intermediate) prevails.
