A series of FeO-CeO₂ nanocomposite catalysts (FeCe-x) were successfully fabricated by hydrogen reduction of hydroxide precursors at temperatures (x) between 200–600 °C. A FeCe-300 catalyst with a Fe:Ce ratio of 2-1 exhibited excellent performance for photothermal CO₂ hydrogenation to CO (CO selectivity = 99.87%, CO production rate 19.61 mmol h⁻¹ g_cat⁻¹, excellent stability). The FeO phase was effective in promoting the reverse water-gas shift (RWGS, CO₂ + H₂ → CO + H₂O). Catalysts prepared at higher reduction temperatures contained both Fe⁰ and FeO, with the Fe⁰ catalyzing the Sabatier reaction (CO₂ + 4H₂ → CH₄ + 2H₂O) and thus lowering FeCe-x catalyst selectivity to CO.

Gold nanoclusters are known to grow stepwise from gold-thiolate monomers and oligomers. Here, the authors find that the evolution of silver nanoclusters differs completely from that of gold: rather than following a bottom-up pathway, the clusters evolve from similarly-sized Ag-thiolate cluster intermediates.

Here, the authors explore how Ni single-atom sites on carbon nitride evolve under photocatalytic conditions. They show that this evolution plays a pivotal role in enhancing photocatalytic H₂O₂ production.

Modulating the electrochemical interface at the atomic level is challenging due to the lack of efficient interfacial regulators. Here, the authors report using a porous amine cage as an interfacial modifier to enhance alkaline hydrogen evolution reaction kinetics by facilitating charge transfer.

The selective oxidative dehydrogenation of ethane is attracting increasing attention as a method for ethylene production. Here, PdZn supported on ZnO affords record-breaking photocatalytic ethane-to-ethylene conversion rate, emphasizing the pivotal role of the interface between PdZn and ZnO in the process.

Single-atom catalysts are a promising class of catalytic materials, but general synthetic methods are limited. Here, the authors develop a ligand-mediated strategy that allows the large-scale synthesis of diverse transition metal single atom catalysts supported on carbon.

The selective semihydrogenation of acetylene in ethylene-rich gas streams is an important process in the manufacture of polyethylene, which is traditionally performed thermocatalytically. Now, a room-temperature electrochemical acetylene reduction system with excellent performance is presented.

Great advances have been made in CO₂ electroreduction, however, the role of wettability-controlled interfacial structures remains poorly understood. Here, the authors apply confocal laser scanning microscopy to gain deeper understanding of these phenomena in gas diffusion electrodes.

Sustainable recycling of waste plastics is of highly strategic significance. Here, the authors report a photothermal recycling system for transforming polyolefin plastics into high-selectivity liquid fuels through the synergistic utilization of ultraviolet, visible, and near-infrared irradiation.

Photothermal Fischer-Tropsch synthesis represents a promising strategy for converting CO into value-added chemicals. Here the authors report a Ru₁Co single atom alloy catalyst for CO photo-hydrogenation to C₅₊ liquid fuels at ambient pressure, and confirm the role of Ru single atoms in promoting CO activation and C-C coupling whilst suppressing CH_x* over-hydrogenation.
