Constructing catalysts with dual active sites is crucial for optimizing adsorption sites and enhancing catalytic performance. Here, uniformly dispersed CuCo alloy and CoO nanosheet composite catalysts with dual active sites were developed, significantly boosting activity in the water-gas shift reaction.

Here, the authors report a Ni(cluster)/TiO₂ catalyst with strong interactions between Ni and −OH strong to promote CO₂ activation with CO adsorption to avoid the activity-selectivity trade-off of the reverse water gas shift reaction.

The direct dissociation of CO₂ into carbonyl (*CO) via a simplified reaction pathway benefits CO₂-related synthesis and catalyst improvement, though the stability of the C = O double bond poses a significant challenge. Here, the authors design a subnano MoO₃ layer on the surface of Mo₂N, offering a dynamically adaptive surface for catalyzing CO₂ hydrogenation.

Oxygen vacancies (O_v) are prevalent anionic defects in transition metal oxides, known for enhancing catalytic performance by modifying the material’s electronic and geometric structure. Here, the authors introduce a novel type of O_v, and materials featuring this rare O_v structure demonstrate excellent performance in the ammonia decomposition reaction.

Rational engineering of interfacial structure is of great interest but it is challenging to construct active dual interfaces. Here, the authors report a strategy to establish stable dual active-interfaces resorting to the boosted oxygen spillover from ceria islets, showing high activity toward the water-gas shift reaction.

Nanoscale supported gold clusters are common redox catalysts but in many cases the nature of the active sites remains unclear. Here, the authors use X-ray absorption to determine the contribution of single gold atoms, clusters and particles on the reactivity of room-temperature carbon monoxide oxidation.

Constructing effective synergistic sites between multiple components in supported catalysts is the key to improve catalytic performance. Here the authors utilized the stress of MoO₃/γ-Mo₂N structure and the interaction between Pt and support to construct an effective catalytic interface for the low-temperature reverse water–gas shift reaction.

Developing effective and stable catalytic interfaces in the medium temperature region is a practical route to replace the existing water gas shift (WGS) process. Here the authors designed a composite Ni-Y₂O₃ catalyst achieving the highest WGS activity for Ni based catalysts.

The technological development requires the future advanced combustion engines be designed to operate at low temperature. Here, the authors show that partially oxide Pt-[O]_x-Bi interface catalyzes CO oxidation at ~ 50 °C via providing moderate CO adsorption and activating CO molecules with electron transformation.

Constructing stable active sites in catalysts for high temperature catalytic reactions remains challenging. Here, the authors manage to make stable copper clusters in the copper‒ceria catalyst with high Cu loading (15 wt.%) for the high-temperature reverse water gas shift reaction.

Cu-CeO₂ has been considered as promising alternative to Cu-Zn-Al catalyst for water-gas shift (WGS) reaction, but it still suffers from low activity caused by Cu sintering. Here, the authors develop inverse CeO₂/Cu catalyst with remarkable activity and stability in WGS via construction of stabilized bulk-nano interfaces.
