Summary: Constructing highly active photocatalysts with rich reactive sites allows for the environmentally friendly utilization of CO2 with organic compounds. In this study, single-atom (SA) decorated two-dimensional (2D) single-layer ZnIn2S4 (ZIS) nanosheet composites with dual active centers of Co and Zn were used for CO2 fixation under visible light. The optimized Co-(s)ZIS composites exhibited significantly improved CO2-epoxide cycloaddition performance, attributing to the unique ensemble that optimizes light harvesting, promotes charge carrier separation, and enriches the bifunctional active sites. This work provides a paradigm for interfacial engineered SA-onto-2D semiconductors and highlights the structure-activity relationship by the well-defined active sites in this SA-based hybrid platform.

Summary: In this study, two different nickel single-atom catalysts (Ni-SACs) were constructed on WO2.72 nanowires, including bulk doping of single Ni atoms in WO2.72 (B-Ni-1/WO2.72) and surface anchoring of single Ni atoms on WO2.72 (S-Ni-1/WO2.72), to explore the electronic structure manipulation for enhancing CO2 photoreduction. The results showed that B-Ni-1/WO2.72 exhibited superior photocatalytic performance compared to S-Ni-1/WO2.72, achieving a CO yield of 80.5 mmol g(-1) h(-1) with a selectivity of 98.7%. This study provides valuable insights into the optimization of site-related electronic structures for efficient single-atom catalysts in artificial photosynthesis.

Summary: Photosynthesis is a sustainable and promising method for low-cost and environment-friendly hydrogen peroxide (H2O2) production. However, its poor carrier utilization and low H2O2 productivity limit its practical use. This study introduces tetrahydroisoquinolines (THIQs) as a distinctive proton donor for efficient H2O2 production and simultaneous generation of highly valuable dihydroisoquinolines (DHIQs) under visible light using dual-functional Zn3In2S6 photocatalyst. Remarkably, the suitably defective Zn3In2S6 achieves a near-stoichiometric co-production of H2O2 and DHIQs at unprecedentedly high rates, outperforming previous reports. The photocatalytic redox reaction mechanism reveals the synergistic effect among reactive oxygen species (ROS), holes (h+), and the proton donor for H2O2 generation, which has been overlooked in previous studies.

Summary: A photocatalyst has been developed by anchoring a Ru complex on CdS quantum dots, achieving selective oxidation of HMF to DFF or HMFCA with high conversion (>81%) and selectivity (>90%). This selective conversion can work well using natural sunlight outside the laboratory, and notably achieves selective production of HMFCA through photocatalytic HMF oxidation for the first time.

Summary: Colloidal quantum dots made of precious-metal-free elements have attractive potential for solar-driven CO2 reduction. However, inhibiting the production of hydrogen remains a challenge. This study presents a carbon-carbon coupling reaction as a solution to block the competing hydrogen evolution in photocatalytic CO2 reduction, using zinc selenide quantum dots as catalysts. Introducing furfural significantly suppresses the evolution of hydrogen and enhances the production of CO.

Summary: The construction of a Z-scheme photocatalytic system is crucial for efficient water splitting and hydrogen evolution. In this study, a novel donor-acceptor covalent organic polymer (COP) is used to construct a COP-ZnIn2S4 (ZIS) heterostructure, which, when combined with platinum (Pt) as a cocatalyst, exhibits a significantly higher hydrogen evolution rate compared to ZIS and Pt/ZIS. The Z-scheme heterostructure enables efficient charge separation, while the cocatalyst improves electron utilization in ZIS, overcoming the rate-limiting steps for hydrogen evolution.

The recent progress in various catalytic approaches, including the use of noble or non-noble metal catalysts in different reaction environments, is discussed. The continuous flow regime for FDMC preparation is also summarized. Furthermore, the perspective towards industrialization of HMF oxidative esterification to FDMC in a more sustainable, efficient, and economical way is proposed.

Summary: Manipulating the structure of photocatalysts at an atomic scale, such as anchoring single Ni atoms on ZnIn2S4 nanosheets, significantly improves photocatalytic performance by promoting carrier separation and prolonging carrier life. In situ ESR confirms that single Ni atoms act as electron trapping centers for proton reduction, leading to a significantly higher hydrogen evolution rate.
