a Powder XRD patterns of the as-synthesized nanoparticles, stored at ambient environment for six months, and the prepared printable ink. The signals are assigned in accordance with the ref. 2 -theta positions of a single-phase BCC structure. a.u., arbitrary units. b High-resolution XPS spectra with peak fitting of Mo 3d, W 4f, and Nb 3d regions. c TEM image of the MoWNb nanostructures featuring an agglomerate with irregular shapes. Inset is the SAED of the nanostructures. d HAADF-STEM image of the MoWNb MEA nanostructures. The white lines indicate the lattice spacing of (110) and (200) planes. e Atomic-resolution HAADF-STEM image taken from the region marked by the box in (d). f Atomic-resolution HAADF-STEM image and the corresponding FFT pattern, revealing a solid solution feature with a BCC structure. g HADDF-STEM images and corresponding element mapping for the MoWNb MEAs, revealing a homogenous distribution of Mo, W, and Nb elements. h EDX pattern of the MoWNb MEAs. arb. units arbitrary units.
