Synthesis of bimetallic sulfides using a crystalline polyoxometalate-based coordination polymer achieved efficient hydrogen evolution reaction

Recent research progress on polyoxometalate-based electrocatalysts in energy generation

“…Additionally, Che et al synthesized a new POM-based metal–organic compound [{Cu(bipy)} 6 (Mo VI 6 O 22 )](PMo V Mo VI 11 O 40 ) as a precursor, which subsequently formed in situ molybdenum sulfide directly coupled to CC within 24 h, resulting in the formation of the MoS 2 –Cu 2 S-CC-24 h electrode with highly dispersed nanosheets. 127 This electrocatalyst demonstrated an outstanding performance for HER in 1.0 M KOH, exhibiting a low overpotential of 159 mV and a smaller Tafel slope of 109 mV dec −1 . Furthermore, the multi-interface engineering strategy has recently attracted significant attention due to its ability to enhance the conductivity of electrocatalysts and the adsorption capacity of the electrochemical intermediates.…”
