FeV₃O₈/MoS₂ nanostructure heterojunctions as a highly effective electrocatalyst for hydrogen evolution

Abstract

Great efforts have been made to explore efficient, stable and resource-rich non-noble metal electrocatalysts instead of noble metal electrocatalysts for the hydrogen evolution reaction (HER).

Hierarchically Self-Supporting Phosphorus-Doped CoMoO4 Nanoflowers Arrays toward Efficient Hydrogen Evolution Reaction

“…Especially, transition-metal oxides (TMOs) display particularly high catalytic activity and remarkable ability to withstand alkaline conditions. 39 The bimetallic oxide catalysts can possibly change the electronic structures of these catalysts by modulating the compositions as well as the physical and chemical properties of the metals. 40 It is believed that bimetallic compounds provide rich active sites, captivating inert sites and simultaneously increasing conductivity.…”

“…However, improving the catalytic activity of these materials remains a significant challenge due to their poor electrical conductivity. , In recent years, numerous research studies have demonstrated the excellent electrocatalytic properties of transition-metal-based compounds. Especially, transition-metal oxides (TMOs) display particularly high catalytic activity and remarkable ability to withstand alkaline conditions . The bimetallic oxide catalysts can possibly change the electronic structures of these catalysts by modulating the compositions as well as the physical and chemical properties of the metals .…”

Self-Sacrificing Template of the POMs-Based Composite for the High-Performance Organic–Inorganic Hybrid Cathode of Lithium-Ion Batteries

“…The signal peaks of FeV 3 O 8 /RGO observed at 200–300 and 645 cm –1 were related to the nonequivalent and stretching vibrations of Fe–O. Signal peaks of 350–500 and 820 cm –1 were assigned to the stretching bands of V–O–V and V–O–e, respectively. , The Raman spectrum region at around 619 cm –1 was attributed to the xanthene ring puckering bonds, while the region from 1195 to 1644 cm –1 in the spectrum was assigned to C–C, C–H, and CC stretching of RB in RB/RGO and FeV 3 O 8 -RB/RGO. , TGA tests for FeV 3 O 8 /RGO and FeV 3 O 8 -RB/RGO were performed, as shown in Figure S6b. The weight loss values of about 5 and 7% at 270 and 395 °C in FeV 3 O 8 /RGO, respectively, were related to the absence of the crystal water and the carbonization of RGO.…”

Atomic order transition of TiNiPt nanoparticles supported on carbon nanotubes for the stable hydrogen evolution reaction

“…The hydrogen evolution reaction (HER) is a key reaction in energy conversion applications such as renewable energy and hydrogen fuel cells. [1][2][3][4][5] Pt is currently considered to be the best HER electrocatalyst, but its low abundance, high cost, low utilization rate, and limited stability limit its development. [6][7][8][9][10] Reducing the amount of Pt and improving the catalytic activity can be achieved by combining Pt with transition metals (such as Ni, 11 W, 12 Ti, 13 Mo, 14 Fe, 15 and Te 16 ).…”
