Catalysis is the increase in the rate of a chemical reaction by the addition of a reagent — the catalyst — that is not itself consumed. The catalyst works by opening up a route between starting material and product with a lower activation barrier than the uncatalyzed process.
Aqueous batteries have drawbacks related to their low energy densities. Now, highly concentrated hetero-halogen electrolytes can be used to enable fast multielectron transfer, leading to cost-effective, reversible and high-energy-density aqueous batteries.
Understanding the ways by which metal-containing catalysts carry out a reaction is a chemical puzzle. Now, investigations of a multi-metallic molecular system uncover how the self-assembly of molecular catalysts facilitates cooperation between active species and improves the conversion of water to hydrogen gas.
An innovative solid-state lithiation strategy allows the exfoliation of layered transition-metal tellurides into nanosheets in an unprecedentedly short time, without sacrificing their quality. The observation of physical phenomena typically seen in highly crystalline TMT nanosheets opens the way to their use in applications such as batteries and micro-supercapacitors.
The use of data science tools in catalysis research has experienced a surge in the past 10–15 years. This Review provides a holistic overview and categorization of the field across the various approaches and subdisciplines in catalysis.
Surface photovoltage microscopy as described in this protocol allows high spatial and energy resolution mapping of surface-charge distributions on photocatalyst particles, enabling rational design of improved materials.
Aminated heteroaromatics are usually synthesized from heteroaromatic substrates. Now, a general photochemical approach that exploits non-aromatic N-heterocyclic ketones as starting materials for the coupling with amines under desaturative catalysis is reported as an alternative.
Crystalline materials’ properties are highly dependent on their size. Here authors report a general synthesis of ultrasmall (4–6 nm) and highly defective Zr/Hf-Metal Organic Frameworks nanoparticles that present enhanced peptide hydrolysis performance.
The development of divergent reaction pathways controlled by different ligands is a critical goal. Here the authors describe a cobalt-catalyzed strategy for cascade coupling of 1,3-enynes with two molecules of acrylates through three reaction modes.
Biomass is a renewable source of carbon that can be exploited to produce valuable chemicals and fuels. This Perspective discusses the electrochemical valorization of biomass, identifying specific chemical transformations in which the approach can excel.

Typically thought of as inert and non-participating atoms, noble gasses adsorbed onto freshly cleaved single crystal surfaces enhance their electronic band structures, potentially creating more active heterogeneous catalysts.
