Co1.4Ni0.6P cocatalysts modified metallic carbon black/g-C3N4 nanosheet Schottky heterojunctions for active and durable photocatalytic H2 production

2D mesoporous ultrathin Cd0.5Zn0.5S nanosheet: Fabrication mechanism and application potential for photocatalytic H2 evolution

“…As expected, the HER polarization curves of the two samples indicated that 7%-NiCo2S4/Cd0.5Zn0.5S had a higher cathodic current density and lower overpotential (Fig. 9(c)) [56,60,62]. By plotting the overpotential with respect to the logarithm of the current (log i), the kinetic parameters of the HER were obtained ( Fig.…”

Constructing low-cost Ni3C/twin-crystal Zn0.5Cd0.5S heterojunction/homojunction nanohybrids for efficient photocatalytic H2 evolution

“…All the electrochemical tests, including the photocurrent-time curves (I-t curves), electrochemical impedance spectroscopy (EIS), and electrocatalytic H2 evolution, were performed according to our previously reported methods [44,[47][48][49][50][51][52].…”

Ni-based photocatalytic H2-production cocatalysts2

“…Inspired by this work, the same group successively fabricated ternary Schottky-based heterojunctions (Fig. 31), including mesoporous g-C3N4/C nanotubes/NiS [224], g-C3N4/acetylene black (AB)/Ni(OH)2 [206], CdS nanosheets/metallic C black/NiS2 [11], and g-C3N4/C black/Co1.4Ni0.6P [317], for highly improved photocatalytic H2 evolution. Among these systems, the metallic C-based Schottky heterojunctions play crucial roles in improving the charge separation from the semiconductor to the Ni-based cocatalyst and subsequently enhancing the electrocatalytic H2-evolution activity and stability of Ni-based cocatalysts, thus resulting in fundamentally improved photocatalytic H2 generation.…”
