“…Electrocatalytic water splitting is an economical and efficient method for hydrogen production 4 , 5 . The hydrogen evolution reaction (HER) as one of the half-reactions of water splitting is an important factor affecting hydrogen production technology, which requires the development of efficient HER catalysts with fast kinetics 6 – 9 . In this regard, the benchmark Pt catalyst is still considered to be the most efficient commercial electrocatalyst for HER.…”

Rational regulation of electrochemical reconfiguration and exploration of activity origin are important foundations for realizing the optimization of electrocatalyst activity, but rather challenging. Herein, we potentially develop a rapid complete reconfiguration strategy for the heterostructures of CoC2O4 coated by MXene nanosheets (CoC2O4@MXene) during the hydrogen evolution reaction (HER) process. The self-assembled CoC2O4@MXene nanotubular structure has high electronic accessibility and abundant electrolyte diffusion channels, which favor the rapid complete reconfiguration. Such rapid reconfiguration creates new actual catalytic active species of Co(OH)2 transformed from CoC2O4, which is coupled with MXene to facilitate charge transfer and decrease the free energy of the Volmer step toward fast HER kinetics. The reconfigured components require low overpotentials of 28 and 216 mV at 10 and 1000 mA cm−2 in alkaline conditions and decent activity and stability in natural seawater. This work gives new insights for understanding the actual active species formation during HER and opens up a new way toward high-performance electrocatalysts.

“…However, it usually needs a much larger voltage of 1.8-2.0 V in the practical electrolysis process, due to the overpotentials on both cathode and anode. Therefore, various kinds of electrocatalysts have been developed to reduce the overpotentials for both HER and OER [9][10][11].…”

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.

“…Hydrogen energy is an efficient and clean secondary energy, which plays an important role in achieving "carbon neutrality". With the expansion of hydrogen production scale and the reduction of cost, hydrogen energy is expected to become the main body of secondary energy together with electricity [1][2][3]. Hydrogen production, storage, transportation, and energy conversion are the four major technical links of hydrogen energy [4][5][6][7][8][9].…”

Porous membrane separation is a competitive hydrogen purification technology due to the advantages of environmental friendliness, energy-saving, simple operation, and low cost. Benefiting from the booming development of materials science and chemical science, great progress has been made in H 2 separation with porous membranes. This review focuses on the latest advances in the design and fabrication of H 2 separation inorganic microporous membranes, with emphasis on the synthetic strategies to achieve structural integrity, continuity and stability. This review starts with a brief introduction to the membrane separation mechanisms, followed by an elaboration on the synthetic challenges and corresponding solutions of various high-performance inorganic microporous membranes based on zeolites, silica, carbon, and metal-organic frameworks (MOFs). At last, by highlighting the prospects of ultrathin two-dimensional (2D) porous membranes, we wish to shed some light on the further development of new materials and membranes for highly efficient hydrogen separation.
