“…For this, considerable efforts have been devoted to exploring various methods to reduce Pt mass loading and exploit other Pt-free electrocatalysts [19][20][21][22][23][24][25][26][27]. Lim and co-workers [28] prepared a Pt@N-containing carbon core-shell catalyst on carbon nanofibers (Pt@CS/CNF), which exhibited excellent catalytic activity and durability. They found that the graphitic N and pyridinic N on the carbon shell could not only offer additional catalytic active sites for HER, but also impede the active Pt core from dissolution and agglomeration, improving the stability (Fig.…”

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.

“…For example, a Pt@C core-shell catalyst was developed, in which graphitic-and pyridine-N on the carbon shell together with Pt nanoparticles served as the active sites for HER. [167,168] Benefited from this specific structure, the carbon shell could not only effectively prevent the dissolution and agglomeration of Pt core, but also allow the facile transport of reactants, improving mechanical stability and minimizing the loss of catalytic activity. In addition, it was also found that the peeling-off issue would become more serious if the interaction between catalyst and support was weaker than the interfacial adhesion force between the catalyst and the bubble.…”

concentration has increased from ≈277 ppm in 1750, prior to Industrial Revolution, to ≈410 ppm in 2019 and the average annual growth of carbon emission in 2018 and 2019 is greater than its 10-year average. [1] Thus, it is urgent to search for renewable and zero-carbon energy sources as alternatives to replace fossil fuels. [2] Although solar, wind and tidal energy are abundant and sustainable, their intermittent and weather-dependent limitations require development and deployment of highly efficient energy conversion and storage systems at large scale to bridge the time gap between supply and demand. [3] An attractive solution is to convert the electrical energy derived from the aforementioned renewable energy sources into chemical energy in the form of hydrogen. [4,5] Pure or mixed hydrogen is playing important roles in transportation, industrial sectors, and chemical transformation processes. [6] However, at present, 95% of hydrogen is still produced by reforming of fossil fuels that emits significant amount of CO 2 and only 4% is through water electrolysis, mainly owing to the much higher production cost of the latter. [7] Therefore, crucial to enable this sustainable vision is to improve the efficiency and scalability of water electrolysis technology.
