  • Tandem catalysts are important in electrocatalysis but suffer from uncontrollable interfaces, limited crystal phases, and complex synthesis. Here, the authors report the facile synthesis of hetero-phase 4H/fcc Au–Cu tandem catalysts with tunable interfaces for ammonia electrosynthesis from nitrate.

  • Twinning is a powerful approach to engineering the physicochemical properties of metallic nanomaterials. Here, the authors discover unusual non-close-packed twinning planes in 4H-phase gold nanokites and show that they can be used as templates to grow 4H-phase twinned nanostructures of other noble metals.

  • Heterometallic nanomaterials in unusual crystal phases that are impossible to form in the bulk state can show interesting physical and chemical properties. Here, crystal-phase heterostructured 4H/fcc Au nanowires are used as seeds to epitaxially grow a variety of binary and ternary hybrid noble metal nanostructures on the phase boundary.

  • Phase transformations between different crystal structures in nanomaterials conventionally require extreme conditions, such as high pressure or high temperature. Here, the authors report the phase transformation of Au nanosheets by the exchange of surface ligands or coating of Ag at ambient conditions.

  • Noble metals typically crystallize with the face-centered cubic structure. Here, the authors report the synthesis of gold nanoribbons in the 4H hexagonal polytype, a previously unreported, metastable phase of gold, and use it to stabilize 4H hexagonal phases of silver, palladium and platinum.

  • The ‘wet’ chemical epitaxial growth of nanostructures on semiconducting surfaces is usually hindered by surface defects. Here, the authors show that large surface area single-layer molybdenum disulphide is an ideal substrate for epitaxial growth of a range of metallic nanoparticles.

  • Properties of nanomaterials respond to changes in the material’s phase, as well as changes in size, composition and morphology. This Review discusses the most recent developments in phase engineering of nanomaterials to afford conventional and unconventional crystal phases, amorphous phases and amorphous–crystalline heterophases.
