Relationship between hydrogen binding energy and activity for hydrogen evolution reaction by palladium supported on sulfur-doped ordered mesoporous carbon

Enhancing Hydrogen Evolution Reaction Activity of Palladium Catalyst by Immobilization on MXene Nanosheets

“…This result highlights the enhanced electrocatalytic performance of the anchored Pd nanoparticles on KMX (Figure b). Furthermore, the HER electrocatalytic performance of PdKMX surpassed that of a commercial 20 wt % Pd/C catalyst, Moreover, the observed HER performance of PdKMX was comparable or even superior to recently reported excellent data for Pd nanoparticle-based HER electrocatalysts (Table S7, Figure c). − This comparison highlights the significance of surface accessibility and stacking control in assembled MXene nanosheets for developing high-performance hybrid electrocatalysts. Additionally, the effect of Pd concentration on the electrocatalyst performance was examined by preparing PdKMX materials with different Pd contents.…”

Precise and scalable fabrication of metal pair-site catalysts enabled by intramolecular integrated donor atoms

“…As shown in Fig. S12,† NSC exhibits the C 1s peak of C–C (284.8 eV), C–O (286.8 eV), 39,40 O 1s peaks of C–OH (533.8 eV), O–COH (532.4 eV) and N–O–C (531.6 eV), 41 N 1s peaks of pyridinic N (398.3 eV) and graphitic N (401.2 eV), 42 as well as S 2p peaks of oxidized S (C–SO x , 168.4 eV), CS–C (165.2 eV) and C–S–C (163.8 eV), 43 demonstrating that the elements and their bonding modes in NSC are consistent with the elemental analysis and FTIR results. The NSC + MPc sample shows the characteristic peaks of C 1s (284.3 and 285.5 eV) and N 1s (399.4 eV) ascribed to the phthalocyanine structure while BM-(NSC + MPc) does not.…”

Doping strategy, properties and application of heteroatom-doped ordered mesoporous carbon

“…Furthermore, the particle size of P t in S-doped OMC was only 1 nm, which was 4 times lower than that in pure OMC. 99 …”
