Zr-MOF/NiS2 hybrids on nickel foam as advanced electrocatalysts for efficient hydrogen evolution

Covalent organic frameworks with interlayer fixed Pt atoms for efficient electrocatalytic hydrogen evolution

“…S16 and Table S4, ESI †). [7][8][9][10][11][12][13][14][15][52][53][54][55][56][57][58][59][60][61][62][63][64][65][66][67][68][69][70][71] The correspondingly calculated Tafel plots for the Pt@TTB-COF catalyst was 21.6 mV dec À1 , which was much lower than that of Pt@TTB-COP (39.0 mV dec À1 ) and Pt/C (23.9 mV dec À1 ), verifying the efficient kinetics of H 2 evolution for Pt@TTB-COF (Fig. 4c and d).…”

Zirconium-based metal–organic frameworks and their roles in electrocatalysis

“…In another recent study, Pan, Lu, Chen and coworkers also demonstrated the incorporation of nickel disulphide (NiS 2 ) into a Zr-MOF. 74 The thin film of UiO-66, a microporous Zr-MOF constructed from terephthalate linkers (see Fig. 1), was first grown on nickel foam (NF), and the high-temperature sulphurisation was performed to further generate the active electrocatalyst for the HER at the MOF/NF interface.…”

Biomimetic Fe7S8/Carbon electrocatalyst from [FeFe]‐Hydrogenase for improving pH‐Universal electrocatalytic hydrogen production

“…[5] However, due to its intrinsic scarcity in nature and high cost, the development of efficient earth-abundant metal-based catalysts is necessary for practical electrochemical water splitting. [6] Recently, transition metal-based oxide, [7,8] phosphide, [9,10] and sulfide [11][12][13] have been extensively studied for HER catalysts. Metal sulfide catalysts have garnered significant attention as they aim to mimic the active sites of hydrogenase enzymes.…”
