The wurtzite phase of CuGaS2. undergoes in situ surface reconstruction, leading to the formation of a thin CuO layer over the pristine catalyst, which facilitates selective conversion of CO2 to ethylene (C2H4). Upon illumination, the catalyst efficiently converts CO2 to C2H4 with 75.1 % selectivity (92.7 % selectivity in terms of R-electron) and a 20.6 mu mol g(-1) h(-1) evolution rate. Subsequent spectroscopic and microscopic studies supported by theoretical analysis revealed operando-generated Cu2+, with the assistance of existing Cu+, functioning as an anchor for the generated *CO and thereby facilitating C-C coupling. This study demonstrates strain-induced in situ surface reconstruction leading to heterojunction formation, which finetunes the oxidation state of Cu and modulates the CO2 reduction reaction pathway to selective formation of ethylene.&lt;/p&gt;

	The photochemical conversion of CO2 into C2+ products has emerged as an attractive method for synthesizing valuable chemicals and fuels using abundant solar energy. However, the challenge lies in enhancing the efficiency and selectivity of C2+ product formation. In this study, we employed a heteroatom doping strategy to optimize the photocatalytic parameters and achieve excellent efficiency and selectivity in the photocatalytic CO2 reduction to C2+ product formation. Our experimental analysis revealed that the local electronic structure of the catalyst, modified by In-doping, enables enhanced efficiency. Additionally, the incorporation of Cu facilitates the coupling of C1 intermediates, resulting in excellent selectivity towards C2+ products. The CO2 reduction performance is further enhanced through exfoliation, which increases the exposure of active sites and extends the charge carrier lifetime by reducing the charge diffusion length. We report that the rate of formation of C2H4 reached 54.3 mu molh(-1)g(-1) with an outstanding selectivity of 91% over the exfoliated CuIn-doped AgBiP2S6 catalyst. By elucidating the role of heteroatom doping and exfoliation in enhancing both the efficiency and selectivity of C2+ product formation, our study contributes to advancing the development of sustainable and efficient photocatalytic CO2 conversion technologies.&lt;/p&gt;

	Developing an efficient and robust photocatalyst for optimal C2+ product generation from carbon dioxide (CO2) is a pressing need in advancing solar fuel production. In this study, we designed an ionic vinylene-bridged conjugated porous organic polymer (Py-POP) enriched with charged pyridine groups via a quaternization-promoted Knoevenagel condensation reaction. The resulting positively charged polymeric framework with shape-persistent nanochannels enabled the uniform assembly of SnS2 units through ionic interactions mediated by amino and sulfhydryl groups. The hybrid porous photopolymer (SnS2@Py-POP) converts CO2 into ethylene with a rate of 34.7 mu mol g-1 h-1 with a selectivity of ethylene around 78.7% under visible light photoirradiation, which outperforms all the C2 selective Sn-based photocatalysts. Our findings principally sheds light on the mechanism of selectivity reversal (from C1 to C2 product) by hybrid catalyst framework engineering. In-depth investigations by synchrotron-based X-ray absorption spectroscopy (XAS) and morphological analysis via high-resolution transmission electron microscopy (HRTEM) reveal the nature of interaction for hybrid heterostructure formation within the porous network. Electron transfer pathways were mapped using time-resolved photoluminescence (TRPL) and transient absorption spectroscopy (TAS), which revealed a Z-scheme electron transfer mechanism. This mechanism facilitates enhanced electron accumulation on the SnS2 layer, promoting efficient CO2 activation and subsequent C-C coupling, ultimately leading to ethylene formation. Furthermore, the ethylene formation mechanism has been investigated in detail by time-resolved diffuse reflectance infrared spectroscopy (TR-DRIFTS), corroborated with density functional theory (DFT). This study opens a new avenue for achieving selectivity reversal in a C1 selective photocatalyst through electronic modulation enabled by the formation of an inorganic-organic hybrid heterostructure.&lt;/p&gt;
