Scheme 7 — 3D MXene-based catalyst for HER

(A) Schematic illustration of template-engaged ultrafast aerosol drying strategy for yielding multilevel hollow MXene tailored low-Pt catalyst with multifunctional catalytic interface and its benefit in promoting the HER under multi-pH conditions.

(B) SEM image and elemental mapping analysis of Pt@mh-3D MXene.

(C) TEM image of Pt@mh-3D MXene.

(D) HRTEM image of Pt nanocrystallites on mh-3D MXene.

(E) A comparison between 2.4% Pt@mh-3D MXene and reported noble metal catalysts in mass activity at η = 100 mV.

(F) Polarization curves of 2.4% Pt@mh-3D MXene and 20% Pt/C for 1st, 20th, and 50th sweeps in natural seawater.⁹⁵ Copyright 2020 WILEY-VCH Verlag GmbH & Co. KGaA, Weinheim.
