Sulfur Vacancy-Engineered Co₃S₄/MoS₂-Interfaced Nanosheet Array for Enhanced Alkaline Overall Water Splitting

A Comprehensive Review on the Boosted Effects of Anion Vacancy in the Photocatalytic Solar Water Splitting: Focus on Sulfur Vacancy

“…The SVs generate defective energy levels to initiate the visible photon absorption and trap photogenerated electrons, facilitating the e/h isolation and hampering the recombination rate . Initio quantum dynamics calculations showed SVs influence nonradiative e/h recombination in MoS 2 , showing the importance of SV for metal dichalcogenides’ conductivity. , This confirms the great importance of designing and fabricating SVs metal sulfides to improve their hydrogen production features by the narrowed E g and prolonged carriers’ lifetime.…”

A review on defect modulated electrocatalysts for the oxygen evolution reaction

“…Up to now, NaBH 4 reducing treatment has been widely used to create defects in V O -Fe-Co 3 O 4 , V O -NiCo 2 O 4 , V O -Co 3 S 4 /CeO 2 , V O -NiFe LDH, V S -Co 3 S 4 /MoS 2 , and V S -Co 3 S 4 /rGO. 10,12,78–81…”

“…In recent years, strategies such as interface optimization, 10,11 heteroatom doping, 12,13 alloying, 14 and defect engineering 15–17 have been employed to enhance the OER performance of non-noble metal catalysts. These approaches aim to optimize the adsorption energies of intermediates and modify the surface atomic properties to boost activity and stability.…”

Simultaneously Improving Energy Storage and Oxygen Evolution Reaction by Causing Regional Defects in MOF-on-MOF Derived Hollow Se-Doped CoP-Fe2P Heterojunctions

“…Transition metal phosphides (TMPs), as n-type semiconductors, have attracted widespread interest in the fields of electrochemical energy storage and electrocatalysis, due to their metallic conductivity and high electrochemical activity compared to transition metal oxides and hydroxides. , Nevertheless, the limited number of active sites within TMPs leads to pure TMPs still failing to meet the ideal operational conditions. Thus, various strategies such as constructing heterostructures, , doping with foreign elements, − and creating vacancies − have been developed to enhance internal activity. In particular, doping with heteroatoms has been recognized as an effective approach to enhance electrochemical performance by modulating electronic structures, inducing lattice distortion, and improving electrochemical valence states .…”
