TL;DR: In this article, the authors reviewed the research progress in the development of carbon-based electrocatalysts toward hydrogen evolution reaction (HER) in acid electrolytes throughout the past few years.

TL;DR: In this article, the authors reported the preparation of Ti 3 C 2 MXene and Ti 2 C MXene by etching Ti 3 AlC 2 with various fluoride salts in hydrochloric acid (HCl), including lithium fluoride (LiF), sodium fluoride (NaF), potassium fluoride (KF), and ammonium fluoride (NH 4 F).

TL;DR: Detailed electrochemical investigations andoretical calculations demonstrate that the nanosheet structure, N doping, and particular crystalline phase of Mo2C produce more exposed Mo active sites, including Mo atoms on the C plane and doped N atoms, which will facilitate the understanding and optimization of Mo-based electrocatalysts in the energy conversion field.

TL;DR: In this article, a single Au nanoparticle of 50-100 nm in diameter was encapsulated within a porous carbon shell embedded with Zn-Fe compounds, and the resulting Au@Zn−Fe-C hybrids exhibited apparent catalytic activity for ORR in 0.1 M KOH (with an onset potential of +0.08 V vs RHE and a stable current density of 10 mA cm−2 at only −0.5 M H2SO4).

TL;DR: In this article, a hierarchical porous carbon rods composed of cross-linked carbon networks (Mo 2 C/CLCN) was synthesized by using Cu-MoO 2 rods as Mo source and Cu template.
