To bolster the dual-circulation development model and green economy, this study delves into the spatiotemporal dynamics of implied carbon transfer in China's inter-provincial and inter-industrial trade, emphasizing its significance for the "dual carbon" objectives. Utilizing multi-regional input-output data from 2012, 2015, and 2017, we employed the multi-region input-output model to gauge embodied carbon transfers across 31 provinces and 28 industries. The Structural Decomposition Analysis (SDA) model further decomposed the growth of trade-related carbon emissions. Key findings include: (1) The electricity and thermal power sectors dominate carbon transfers, with secondary industries seeing rapid growth; (2) Northern provinces significantly outweigh southern ones in carbon transfers and the main direction of it is towards affluent southern coastal regions; (3) Scale effect plays a pivotal role in these transfers. Conclusively, it is crucial for regulatory authorities to rationally formulate region-specific emission policies for inter-regional coordination, and future studies can focus on industrial and spatial clustering effects.

Dye wastewater green treatment has always been one of the research hotspots in the environmental protection and remediation field. The photocatalytic degradation and mineralization of organic dyes are considered to be an energy conservation and effective wastewater remediation technology. Novel CuWO4/WO3 S-scheme nano-heterojunction microspheres were prepared through a convenient hydrothermal route and impregnation–calcination method. The structure, composition, electrochemistry and optical properties of the nano-heterojunction microspheres were systematically evaluated via XRD, SEM, TEM, electrochemical analysis and spectrometry, and the photocatalytic activity of CuWO4/WO3 was investigated using methylene blue (MB) as the probe under visible light irradiation. The CuWO4/WO3 S-scheme nano-heterojunction exhibited a boosted photocatalytic activity compared with WO3 owing to a decrease in carrier transfer resistance and an increase in carrier separation efficiency. The MB degradation rate of the CuWO4/WO3-10 S-scheme nano-heterojunction microspheres is 1.83 and 3.10 times higher than that of pure WO3·2H2O and WO3 microspheres, respectively. Based on the active species capture experiments and the Mott–Schottky curve, an S-scheme mechanism of the photogenerated carrier transfer was elucidated. This study reveals a design and method for the synthesis of S-scheme nano-heterojunction catalysts for application in the wastewater purification field. [ABSTRACT FROM AUTHOR]

Photothermal CO2 reduction using H2O combined with photocatalysis‐driven H2O splitting combined with thermal catalysis‐supported CO2 reduction has attracted rapid interest in artificial synthesis of solar fuel. With respect to extremely efficient photothermal catalysis, the photothermal impact of TMDCs (Transition Metal Dichalcogenides) facilitates CO2 reduction by activating lattice oxygen in oxide to enhance H2O oxidation. However, the fixed band gap of single photocatalyst is limited. The purpose of this work is to expand the band gap and improve the redox capacity. Hollow boxwood ball‐like WO3/WS2 Z‐scheme heterojunctions were prepared and used for photothermal catalytic CO2 reduction. DFT calculations and UV‐Vis spectra show LSPR effect in WOS heterojunctions, and the optical response extends to near infrared region. By comparison, the photothermal catalytic reduction of WO3/WS2 (9.717 μmol) by CO2 at 513 K is higher than that at 298 K (1.198 μmol) by a factor of 8. The formation of Z‐scheme heterojunction promotes rapid carrier transfer and lowers the reaction energy barrier. As well as the hollow structure improves light utilization and increases the interfacial area and number of active sites. In addition, the WO3/WS2 heterostructure utilizes its unique LSPR effect to generate heat through the photothermal effect, which can also promote molecular activation. This work reveals the important role of the LSPR effect in photothermal catalysis and demonstrates a TMDCs‐based photothermal‐driven catalysts, which presents a promising approach for designing of photothermal catalytic CO2 reduction.
