Controllable fabrication and structure evolution of hierarchical 1T-MoS2 nanospheres for efficient hydrogen evolution

Tuning the electronic communication of the Ru–O bond in ultrafine Ru nanoparticles to boost the alkaline electrocatalytic hydrogen production activity at large current density

“…5f). 43,44 It could be seen that the activity of the Ru–O/C-600 electrocatalyst remained stable for at least 50 h with almost no decay. On the other hand, after 2000 cycles of CV, the HER polarization curve only showed slight attenuation.…”

Tailoring the fusion effect of phase-engineered 1T/2H-MoS2 towards photocatalytic hydrogen evolution

“…In short, all the 1T/2H-MoS 2 photocatalysts in comparison to 2H-MoS 2 exhibit increased stability along with a significant boost in photocurrent production under visible light illumination. 43,46,47…”

“…The smaller arc diameter of 30-1T/2H-MoS 2 may be attributed to the presence of dense active sites over the edges and basal plane of the 1T phase, generating additional conductive channels and thereby causing facile charge transfer and less e − /h + pair recombination. 46…”

“…Comparing the Nyquist plots of all the photocatalysts, as shown in Fig.6, it is noticed that the semicircle decreases from 15-1T/2H-MoS 2 to 30-1T/2H-MoS 2 and then increases for 45-1T/2H-MoS 2 , indicating the variation of the 1T phase in the as-prepared photocatalysts. The smaller arc diameter of 30-1T/2H-MoS 2 may be attributed to the presence of dense active sites over the edges and basal plane of the 1T phase, generating additional conductive channels and thereby causing facile charge transfer and less e À /h + pair recombination 46.…”

Anchoring Sites Engineering in Single‐Atom Catalysts for Highly Efficient Electrochemical Energy Conversion Reactions

“…[3,4] For example, water splitting electrolyzers powered by electricity can split H 2 O molecules to generate clean and renewable hydrogen energy with the cathodic hydrogen evolution reaction (HER) and anodic oxygen evolution reaction (OER). [5][6][7][8][9][10][11] In the reverse reaction, fuel cells can transform chemical energy into electricity with the cathodic oxygen reduction reaction (ORR) and anodic hydrogen oxidation reaction. [12][13][14] Besides, CO 2 reduction reaction (CO 2 RR) and nitrogen reduction reaction (NRR) have become the emerging and hot research areas due to their encouraging application for electrochemical synthesis of vital chemical feed stocks such as ethylene and ammonia.…”
