研究目的
To overcome the problem of the huge Zn loss during the nitridation process in the synthesis of ZnO-co-doped GaN, a promising catalyst for photocatalytic overall water splitting in the visible light range, by applying moisture-assisted nitridation of a co-precipitated GaZn precursor under milder conditions.
研究成果
The Zn loss due to volatilization during the nitridation process can be completely suppressed by using moisture-assisted nitridation of co-precipitated GaZn precursors. This method allows for the synthesis of GaN:ZnO particles with high Zn content and adjustable Ga:Zn ratios, though with increased defect density and structural disorder at higher Zn contents.
研究不足
The GaN:ZnO materials synthesized have a lower degree of crystallinity compared to those prepared by the classic high-temperature solid-state synthesis approach, potentially affecting their photocatalytic activity.
