Summary: Porphyrin and its derivatives combined with first-row transition metals have been widely used for electrochemical and photocatalytic applications. Co-TCPP anchored on TiO2 showed high photoactivity for CO production under UV-visible light irradiation. The photoactivity drop could be solved by removing hydroxy ligands through ethanol treatment, leading to an increased CO photoformation rate.

Summary: Carbon cycling and value-added CO2 utilization through photocatalytic CO2 reduction are effective strategies for solving environmental problems and energy crises. In this study, a double p-n heterostructured CeO2@CdS-Cu8S5 double-shelled hollow sphere (DSHSs) photocatalyst was designed and fabricated, which exhibited efficient and stable photocatalytic CO2 reduction under visible light irradiation. The optimized CeO2@CdS-Cu8S5 DSHSs without any noble metal cocatalyst showed excellent activity (18.25 μmol g-1h-1) and high selectivity (89.3%) during the photocatalytic reduction of CO2 deoxygenation to CH4.

Summary: The study synthesized zeolite TS-1 co-loaded with silver and titanium dioxide nanoparticles using ion-exchange and in-situ photodeposition methods, resulting in a sample with high surface area, rich defects, and highly dispersed silver nanoparticles. The sample exhibited high CO2 adsorption capacity and improved separation efficiency of photogenerated electron-hole pairs, leading to selective CO and CH4 production with suppressed H2 evolution during photocatalytic CO2 conversion. The super photocatalytic activity was attributed to the synergistic effect among the dispersed silver nanoparticles, support zeolite TS-1, and titanium dioxide with highly exposed {101} planes.

Summary: The Ruthenium-Cobalt photocatalytic system (RCPS) is a leading candidate for integrating homocatalysis and heterocatalysis, and has gained significant research attention in photocatalytic CO2 reduction reaction (PCO2RR). The coordination environment of the catalytic site and the efficiency of electron transfer are crucial in determining the reaction pathways in PCO2RR, highlighting the importance of evaluating and guiding PCO2RR. This comprehensive review aims to provide a systematic examination of RCPS in CO2 reduction, discussing recent progress on the coordination effect of Ru-Co in homogeneous and heterogeneous photocatalysis systems. The review also covers advanced characterization techniques, challenges in first-principal density functional theory, and future perspectives for RCPS research.

Summary: In this study, a hybrid catalyst system was employed to enhance the efficiency and stability of a molecular bipyridyl Ru(II)-complex-based photocatalytic system for CO2 reduction. Fixed molecular Ru(II) complex on TiO2 was found to suppress the deactivation product formation and promote the monomeric catalytic route, resulting in significantly increased activity and durability compared to homogeneous catalysis. The catalytic strategy produced high turnover numbers for CO and HCOO- production in CO2-saturated solution.

Summary: In this study, multi-prismatic hollow cubic CeVO4 microstructures were fabricated using a one-step solvothermal method without organic agents. The wall thickness of the CeVO4 microstructures changed radially with the quadrangular prism. Excessive V precursor favored the formation of hollow micro-cubic CeVO4 with wall thickness changing from 200 to 700 nm. These CeVO4 microstructures exhibited superior photocatalytic activity for CO2 reduction under visible light, with a maximum CO generation rate several times higher than other samples. This study provides guidelines for fabricating multi-assembled structures of ternary compounds and expands the exploration of spatial structure in multivariate compounds.

Summary: This work designed an advanced photocatalytic system composed of titanium dioxide (P25) and mSFO (Sn-doped magnetite with Fe-doped cassiterite) for gas phase CO2 reduction. A synthesis route of mSFO composite was proposed, and the obtained material was characterized by various techniques. The mSFO/P25 system showed photocatalytic reduction ability of CO2 to CO, which was confirmed by the use of labeled carbon dioxide. The surface photovoltage and electrochemical measurements supported the S-scheme mechanism.

Summary: This study demonstrates efficient CO2 conversion by modulating the Cu/TiO2 composite. The optimal sample shows significant transfer of Cu 3d electrons to Ti's t(2g) orbital, supported by X-ray absorption spectroscopy and Raman spectra. Theoretical calculations suggest a decline in the energy of Ti 3d orbital in TiO2, facilitating the acceptance of Cu 3d electrons. The Cu/TiO2 composite exhibits highly selective CO conversion performance.

Summary: A novel aqueous biphasic system (ABS) composed of acetonitrile and amine solution has been constructed and applied for water purification, using CO2 gas flush process and low cost materials. Factors such as temperature and ratio distribution were found to play key roles in ABS formation, with lower temperature being beneficial. High extraction efficiency towards different metal ions was achieved, broadening the scope of ABS construction and deepening the understanding of its mechanism.
