“…Decreasing particle size or preparing ultrathin structure is an effective method to maximize surface area and expose more active sites [80], beneficial for improving the catalytic activity [81,82]. Ultrafine monodisperse Ir NPs with narrow size distribution and high dispersion were successfully synthesized through a colloidal method [52].…”

Hydrogen, as a clean energy carrier, is of great potential to be an alternative fuel in the future. Proton exchange membrane (PEM) water electrolysis is hailed as the most desired technology for high purity hydrogen production and self-consistent with volatility of renewable energies, has ignited much attention in the past decades based on the high current density, greater energy efficiency, small mass-volume characteristic, easy handling and maintenance. To date, substantial efforts have been devoted to the development of advanced electrocatalysts to improve electrolytic efficiency and reduce the cost of PEM electrolyser. In this review, we firstly compare the alkaline water electrolysis (AWE), solid oxide electrolysis (SOE), and PEM water electrolysis and highlight the advantages of PEM water electrolysis. Furthermore, we summarize the recent progress in PEM water electrolysis including hydrogen evolution reaction (HER) and oxygen evolution reaction (OER) electrocatalysts in the acidic electrolyte. We also introduce other PEM cell components (including membrane electrode assembly, current collector, and bipolar plate). Finally, the current challenges and an outlook for the future development of PEM water electrolysis technology for application in future hydrogen production are provided.

“…Unsaturated coordination environments, unique electronic structures and quantum size effect bring SACs widespread application as well as distinguished catalytic performance beyond our expectation. [11] Benefited from these advantages, SACs have been extensively applied in electrocatalytic reactions, such as ORR, [16][17][18] OER, [19][20][21] and CO 2 RR. [22][23][24] Although SACs exhibit particular advantages, some intrinsic defects limit their further development: (1) when it comes to complex processes involving multiple reactive intermediates, all of them are adsorbed on the same active center.…”

Atomically dispersed metal catalysts have been widely used in electrocatalysis because of their outstanding catalytic activity and high atomic utilization efficiency. As an extension of single‐atom catalysts (SACs), dual‐atom catalysts (DACs) provide new insights for the development of atomic‐scale catalysts. Higher metal loading and more flexible active sites endow DACs with improved catalytic performance as well as optimized reaction mechanism model. In this review, DACs are firstly classified according to their configurations and metal sites. Subsequently, the synthetic strategies and characterization techniques of DACs are introduced. Furthermore, the applications of DACs are exemplified in various electrocatalytic reactions, including oxygen reduction reaction, oxygen evolution reaction and carbon dioxide reduction reaction. Finally, the prospects to be expected and challenges to be faced with are discussed.

“…While achieving their biological functions in multienzyme catalytic cascades [3][4][5], enzymes can, when compatible with chemocatalysts, possess high activity and enantioselectivity under certain conditions [6,7]. In comparison to the enzyme cascades, chemocatalysts with a range of new advantages may enrich the enzymes' repertoire, such as good stability, various substrate choices, and diverse reaction types [8]. However, the reaction conditions of biocatalysts are usually different from those of the chemocatalysts in that the two types of catalysts are frequently deactivated in the one-pot reaction process [6].…”

Chemo-Biocascade Reactions Enabled by Metal–Organic Framework Micro-Nanoreactor

The one-pot combination of biocatalytic and chemocatalytic reactions represents an economically and ecologically attractive concept in the emerging cascade processes for manufacturing. The mutual incompatibility of biocatalysis and chemocatalysis, however, usually causes the deactivation of catalysts, the mismatching of reaction dynamic, and further challenges their integration into concurrent chemo-biocascades. Herein, we have developed a convenient strategy to construct versatile functional metal–organic framework micro-nanoreactors (MOF–MNRs), which can realize not only the encapsulation and protection of biocatalysts but also the controllable transmission of substances and the mutual communication of the incompatible chemo-biosystems. Importantly, the MOFs serving as the shell of MNRs have the capability of enriching the chemocatalysts on the surface and improving the activity of the chemocatalysts to sufficiently match the optimum aqueous reaction system of biocatalysts, which greatly increase the efficiency in the combined concurrent chemo-biocatalysis. Such strategy of constructing MOF–MNRs provides a unique platform for connecting the “two worlds” of chemocatalysis and biocatalysis.
