摘要：

Based on the idea that a heterojunction can significantly promote photoelectrochemical (PEC) efficiency, BiVO<INF>4</INF>/PANI (polyaniline), as a Z-scheme heterojunction, was designed in this work. BiVO<INF>4</INF>/PANI achieved a desirable NH<INF>3</INF> yield rate (r<INF>NH<INF>3</INF></INF> = 0.93 mu g h-1 cm-2) and faradaic efficiency (FE = 26.43%). This study presents novel insight into PEC NRR research, and it could be extended to the modification of other catalysts for boosting PEC N<INF>2</INF> reduction reaction performance.
