Effects of solvent‐induced morphology evolution of Zn2GeO4 on photocatalytic activities of g‐C3N4/Zn2GeO4 composites

Abstract: Morphology modulation of photocatalyst has been demonstrated to be a crucial strategy for improving the catalytic performance in solar energy conversion system. Here we systematically investigated the influence of the solvent-dependent morphology evolution of Zn 2 GeO 4 phase on the photocatalytic efficiency of the as-prepared g-C 3 N 4 /Zn 2 GeO 4 composites. The morphologies of Zn 2 GeO 4 were rationally tuned from flower-like nanosheets to length-controllable nanorods, and microclusters assembled from micro… Show more

“…ZnO 是 Zn 最简单的 氧化物, 禁带宽度为 3.37 eV, 与 TiO 2 接近, 由于其来源 丰富、性质稳定, 在光催化和热化学分解 CO 2 领域中均 受到深入的研究 [23][24][25] . 而 Zn 2 GeO 4 是一种宽禁带半导体, 仅能响应深紫外光(<350 nm), 但由于其独特的 d 10 电子 构型以及良好的氧空位形成能力也受到了研究人员的 关注 [26][27][28] . 光热协同反应对催化材料的光响应以及氧空 位形成能力均有一定要求 [29] .…”

“…[17][18][19] However, the photocatalytic activity of g-C 3 N 4 was limited by the small specic surface area, high combination rate of photogenerated electron-hole pairs and low utilization efficiency of the visible light. 18,20,21 Consequently, some strategies such as element doping, 22,23 constructing heterojunction [24][25][26] and morphology control 27,28 have been adopted to enhance the photocatalytic performance of g-C 3 N 4 . Among them, increasing the specic surface area was regarded as the more simply and practical way to modify the g-C 3 N 4 .…”
