S-Scheme Heterojunction ZnCdS Nanoparticles on Layered Ni–Co Hydroxide for Photocatalytic Hydrogen Evolution

ACS Applied Nano Materials, Год журнала: 2024, Номер 7(6), С. 6056 - 6067

Опубликована: Март 1, 2024

Photocatalytic hydrogen evolution technology faces great challenges in designing efficient and stable catalysts that absorb visible light. In this study, a catalyst with S-scheme heterojunction built-in electric fields was successfully prepared by electrostatic self-assembly to load ZnCdS nanoparticles on layered Ni–Co. The ZnCdS/NiCo double hydroxide (NiCo-LDH) test demonstrates the effectively inhibit recombination of photogenerated electrons holes, lowering impedance increasing photocurrent. Additionally, more can take part reduction reaction, producing H2. It is worth noting ZnCdS/NiCo-LDH 1153 μmol 5 h, which 10 times ZnCdS. We analyze electron transport process, construction field, formation during situ X-ray photoelectron spectroscopy. This study provides new perspective for application LDH photocatalysis direction breakthrough photocatalytic research.

Preparation and Photocatalytic Hydrogen Evolution Performance Study of NENU‐5/CuBr/Graphdiyne Tandem S‐Scheme Heterojunction

Solar RRL, Год журнала: 2024, Номер 8(12)

Опубликована: Апрель 29, 2024

Graphdiyne (GDY) has been widely applied in the field of photocatalytic hydrogen production due to its unique chemical structure and excellent photoelectric performance. Herein, CuBr is used as a catalytic substrate prepare CuBr/GDY through cross‐coupling reaction, novel NENU‐5/CuBr/GDY tandem S‐scheme heterojunction photocatalyst constructed at low temperature. The exhibits significantly enhanced activity evolution, with evolution reaching 226.62 μmol 5 h, which 4.7 12.6 times greater than that pure GDY NENU‐5, respectively. Comprehensive evaluation electrochemical, photoluminescence, time‐resolved photoluminescence indicates composite catalyst attributed high photocurrent response electrical resistance, increases efficiency photogenerated charge separation. Additionally, density functional theory calculations ultraviolet photoelectron spectroscopy propose possibility constructing structure. In summary, this work provides valuable ideas into heterojunctions for production.
