  • The reaction mechanism of carbon dioxide to high-value hydrocarbons over metal-zeolite bifunctional catalysts remains ambiguous. Here, the authors demonstrate that active zeolite catalysts’ topology and hybrid nature are descriptors; regulating the reaction mechanism and ultimate product selectivity.

  • Federated learning can be used to train medical AI models on sensitive personal data while preserving important privacy properties; however, the sensitive nature of the data makes it difficult to evaluate approaches reproducibly on real data. The MedPerf project presented by Karargyris et al. provides the tools and infrastructure to distribute models to healthcare facilities, such that they can be trained and evaluated in realistic settings.

  • A low-valence carbon-doped ruthenium oxide-based catalytic material achieved a catalytic trinity of superior activity, selectivity and stability during the conversion of carbon dioxide into methane at low temperatures.

  • The direct transformation of crude oil to chemicals can become a game changer in refocusing the petroleum industry production, but remains technically challenging. Here, the authors introduce a multi-zone fluidized bed reactor in combination with an engineered cracking catalyst for the efficient one-pot production of light olefins from crude oil.

  • The accessibility of materials’ porous domains is typically explored through bulk, and often non-visual, measurements. Now, an integrated fluorescence microscopy approach has established a direct visual relationship between pore architecture (which depends on pore sizes and interconnectivity), molecular transport, and in turn catalytic performance in industrial-grade catalyst particles.

  • Bioethanol-based alkylation of benzene is a potentially sustainable route to commodity chemicals, but there is little knowledge of the reaction mechanism. Here, Weckhuysen and co-workers study the zeolite catalysed alkylation of benzene with ethanol, identifying the active alkylating agent and experimentally show the presence of a σ-complex intermediate.

  • The conversion of methanol — which can be produced from non-fossil resources — to important chemical commodities such as olefins and aromatics allows for the diversification of organic feedstocks beyond petrochemicals. This Review covers recent discoveries about the mechanism of this process and discusses how these link to practical aspects in reaction engineering.
