    Efforts to find renewable alternatives to fossil fuels that might enable a carbon-neutral society by 2050 are described, as well as outlining a possible roadmap towards a refinery of the future and evaluating its requirements.

    Rhodium catalysts confined in zeolite pores exhibit high regioselectivity in the hydroformylation process of propene to high-value n-butanal, surpassing the performance of all heterogeneous and most homogeneous catalysts developed so far.

    We report a strategy that yields thermally and hydrothermally stable silicates by expansion of a one-dimensional silicate chain with an intercalated silylating agent that separates and connects the chains.

    The authors identify a dynamic site renewal and decay cycle, mediated by proton transfers involving proximal Brønsted acidic OH groups, which operates concurrently with the Chauvin cycle and could address roadblocks associated with industrial metathesis processes.

    Nanometre-sized ‘nanoglue’ islands of CeOx on high-surface-area SiO2 are shown to suppress sintering and confine on average one Pt atom per island, leading to stable single-atom catalysts under oxidizing and reducing environments.

    Catalysts consisting of oxide-supported pair sites can enable bifunctional reaction mechanisms with high activity and selectivity for reactions and so overcome the limitations in industry imposed by the use of homogeneous catalysts.

    ‘Cooperative redox enhancement (CORE) effects, which arise through the coupling of oxidative dehydrogenation and oxygen reduction reactions, can lead to increased rates of reaction over spatially separated bimetallic heterogeneous catalysts.

    Propene is obtained through propane dehydrogenation using catalysts that are toxic, expensive or demanding to regenerate with ecologically harmful compounds, but the ZnO-based alternative reported here is cheap, clean and scalable.

  • Article |

    Spectroscopic studies and theoretical calculations of the electrocatalytic oxygen evolution reaction establish that reaction rates depend on the amount of charge stored in the electrocatalyst, and not on the applied potential.

    The mechanism of hydrogen spillover is described using a precisely nanofabricated model system, explaining why it is slower on an aluminum oxide catalyst support than on a titanium oxide catalyst support.

  • Letter |

    The flavouring, perfume and pharmaceutical industries rely on the selective hydrogenation of α,β-unsaturated aldehydes to generate unsaturated alcohols; here, a new type of highly selective catalyst is described in which platinum nanoparticles are sandwiched between a core and a shell of a metal−organic framework.

    Lower olefins are hydrocarbons that are widely used in the chemical industry, and can be generated from syngas by the ‘Fischer–Tropsch to olefins’ process; here, a new catalyst is described that can generate lower olefins from syngas with high selectivity, with little formation of undesirable methane.

    Iron-containing zeolites have an exceptional ability to convert methane into methanol, but their active site have been hard to study; now, magnetic circular dichroism has been used to explore the reactive species, providing a technique that should be generally applicable, and revealing the value of constraining active sites within a lattice to improve catalyst functionality.

  • Letter |

    Using single-molecule fluorescence imaging of photoelectrocatalysis, the charge-carrier activities on single TiO2 nanorods and the corresponding water-oxidation photocurrent are mapped at high spatiotemporal resolution, revealing the best catalytic sites and the most effective sites for depositing an oxygen evolution catalyst.

    The conversion of hydrocarbons to produce high-quality diesel fuel can be catalysed by bifunctional materials that contain a metal site and an acid site; it has been assumed that these sites should be as close as possible in order to enhance catalysis, but it is now shown that having them too close together can be detrimental to selectivity.

    A technique of NMR thermometry that relies on the inverse relationship between NMR linewidths and temperature can be used to map non-invasively the gas temperatures inside catalytic reactors, offering unprecedented capabilities for testing the approximations used in reactor modelling.
