研究目的
Investigating the photocatalytic H2 evolution activity of novel noble-metal-free Ni12P5/CdS composite under visible light irradiation.
研究成果
The Ni12P5/CdS composite exhibits excellent photocatalytic H2 evolution activity under visible light, attributed to the efficient separation of photocarriers via a direct Z-scheme mechanism. This study opens new avenues for using noble-metal-free Ni12P5 as a co-catalyst in CdS-based photocatalysts.
研究不足
The low content of Ni12P5 in the composite may limit the full potential of photocatalytic activity enhancement.
1：Experimental Design and Method Selection:
A hydrothermal method was used to synthesize Ni12P5/CdS composite.
2：Sample Selection and Data Sources:
CdS nanorods were prepared by a modified solvothermal method. Ni12P5/CdS was synthesized by dissolving Ni(NO3)2·6H2O in deionized water, then dispersing red P and CdS nanorods in the solution, and heating in a Teflon-lined stainless steel autoclave.
3：List of Experimental Equipment and Materials:
X-ray powder diffractometer (XRD, BRUKER D8 ADVANCE), X-ray photoelectron spectroscopy (XPS, Thermo ESCALAB 250), scanning electron microscopy (SEM, FEI Sirion 200), high-resolution transmission electron microscopy (HRTEM, JEOL-2011), UV–Vis diffuse reflectance spectrophotometer (DRS, TU-1901), and electrochemical system (CHI660E).
4：Experimental Procedures and Operational Workflow:
Photocatalytic property was measured on a photocatalytic equipment (CEL-SPH2N) with a 300 W Xe lamp and a 420 nm cut-off filter.
5：Data Analysis Methods:
The resulting H2 was analyzed by GC-7900 gas chromatograph.
