“…Compared with single-element metal materials, multi-element alloys have attracted attention in recent years because of their mechanical, physical, and chemical properties resulting from the entropy increase (19)(20)(21). The properties of alloy catalysts can be modified by additional elements, similar to how soluble metal complex catalysts can be modified by tuning ligands to modify active sites and their interaction with solvents (22)(23)(24).…”

Methane pyrolysis (MP) is a potential technology for CO 2 -free hydrogen production that generates only solid carbon by-products. However, developing a highly efficient catalyst for stable methane pyrolysis at a moderate temperature has been challenging. We present a new and highly efficient catalyst created by modifying a Ni-Bi liquid alloy with the addition of Mo to produce a ternary NiMo-Bi liquid alloy catalyst (LAC). This catalyst exhibited a considerably low activation energy of 81.2 kilojoules per mole, which enabled MP at temperatures between 450 and 800 Celsius and a hydrogen generation efficiency of 4.05 ml per gram of nickel per minute. At 800 Celsius, the catalyst exhibited 100% H 2 selectivity and 120 hours of stability.

“…The development of functional materials is an important key to solving various problems in human society. Functional materials have been created together with developments of well-established science such as organic chemistry [4][5][6], inorganic chemistry [7][8][9], polymer chemistry [10][11][12], supramolecular chemistry [13][14][15], coordination chemistry [16][17][18], other materials chemistry [19][20][21], and bio-related chemistry [22][23][24]. Accordingly, it has become clear that precise control of structures is necessary to improve functionality [25,26].…”

The development of nanotechnology has provided an opportunity to integrate a wide range of phenomena and disciplines from the atomic scale, the molecular scale, and the nanoscale into materials. Nanoarchitectonics as a post-nanotechnology concept is a methodology for developing functional material systems using units such as atoms, molecules, and nanomaterials. Especially, molecular nanoarchitectonics has been strongly promoted recently by incorporating nanotechnological methods into organic synthesis. Examples of research that have attracted attention include the direct observation of organic synthesis processes at the molecular level with high resolution, and the control of organic syntheses with probe microscope tips. These can also be considered as starting points for nanoarchitectonics. In this review, these examples of molecular nanoarchitectonics are introduced, and future prospects of nanoarchitectonics are discussed. The fusion of basic science and the application of practical functional materials will complete materials chemistry for everything.

“…18 This method has the potential to be an effective general method to synthesize smaller UMEA NPs. However, most MEA NPs synthesized by chemical reduction methods are composed of elements with high and similar redox potentials, such as platinum group metals (PGMs), 19,20 and UMEA NPs with more than 10 elements have not yet been reported. This is mainly because of the largely different redox potentials of multiple elements.…”

Multielement alloy nanoparticles have attracted much attention due to their attractive catalytic properties derived from the multiple interactions of adjacent multielement atoms. However, mixing multiple elements in ultrasmall nanoparticles from a wide range of elements on the periodic table is still challenging because the elements have different properties and miscibility. Herein, we developed a benchtop 4-way flow reactor for chemical synthesis of ultra-multielement alloy (UMEA) nanoparticles composed of d-block and p-block elements. BiCoCuFeGaInIrNiPdPtRhRuSbSnTi 15-element alloy nanoparticles composed of group IV to XV elements were synthesized by sequential injection of metal precursors using the reactor. This methodology realized the formation of UMEA nanoparticles at low temperature (66 °C), resulting in a 1.9 nm ultrasmall average particle size. The UMEA nanoparticles have high durability and activity for electrochemical alcohol oxidation reactions and high tolerance to CO poisoning. These results suggest that the multiple interactions of UMEA efficiently promote the multistep alcohol oxidation reaction.
