  • Iron-based catalysts are desirable for Fischer–Tropsch synthesis but are often hindered by deactivation arising from sintering or phase change. Here, the authors report the metal-organic framework-mediated synthesis of dispersed iron carbide catalysts and demonstrate their activity and stability.

  • Preparation of supported catalysts with high nanoparticle loading is a considerable synthetic challenge. Here, by using a metal organic framework as sacrificial template, the authors report a cobalt catalyst with a 50% Co loading with superior activity in the C5+ selective production of hydrocarbons from syngas.

  • As of yet, no clear structure–performance descriptors have been developed to tune the catalytic activity of zeolitic methanol-to-olefin catalysts. Now it has been shown that introducing Lewis acidity into Brønsted acidic zeolites boosts their performance. Although Brønsted acidity is found to define propylene selectivity, Lewis acidity is responsible for prolonging lifetime.

  • A bottom-up approach for producing metal–organic framework lamellae of micrometre lateral dimensions and nanometre thickness that can be incorporated into polymer matrices is now presented. These composite materials exhibit outstanding CO2 separation performances on exposure to CO2/CH4 gas mixtures.

  • Mechanochemistry is a promising technology to tackle current and future polymer waste streams for a sustainable future. With this review, we take into account synthetic, computational, technical, and engineering perspectives to converge trituration and polymer mechanochemistry with a particular focus on the fate of commodity polymers and potential technologies to monitor mechanochemical reactions while they occur. We highlight the need for future transdisciplinary research to tackle the high-leverage parameters governing an eventually successful mechanochemical polymer degradation approach for a circular economy.
